C
A
River
water
in
this
in
this
situation
is
highly
temporal
through
the
season,
as
well,
so
with
all
around
in
the
wet
season.
The
fresh
water
blasts
through
the
system-
and
you
have
this
big
plume
of
fresh
water
going
in
and
the
Bay
of
Bengal,
then
slowly
as
those
rivers
dry
up
of
their
snow
melt,
water
up
at
lima
layers
that
sea
water
starts
coming
back
up
the
stream
and
back
into
our
soil
environment.
So
we
have
temporal
effect
of
salinity.
A
D
A
Of
the
debate,
so
what
is
the
problem?
Well,
besides
the
fact
we
have
a
massive
population
that
need
to
improve
their
livelihoods
and
improve
their
food
security.
We've
got
the
temporal
salinity,
which
really
inhibits
our
capacity
to
interpret
cropping
trials.
Now
our
job
in
this
project
is
to
is
to
try
and
get
or
increase
the
agricultural
production
by
growing
shorter
season
varieties
having
early
so
excelling.
E
B
A
A
A
F
A
F
A
So
this
game
is
the
idea
that
we
probably
should
be
trying
to
use
them
in
this
environment,
so
we
went
off
and
bought
that
the
other
instrument
that
was
on
that
first
whoops
this.
This
instrument
here
is
a
Julie
m1
SH,
it's
very
similar
to
an
am
38,
except
that
it
has
four
coil
separations,
giving
us
full
effective
depths
of
inquiry
within
the
root
zone.
The
top
meter
and
half.
A
A
As
cassava
Rama
in
the
in
the
in
West
Bengal,
the
points
here
are
points
taken
on
individual
trial.
Plots
like
you
saw
in
that
previous
slide.
I
can't
remember
what
what
the
crop
was
in
this
instance,
but
these
are
the
raw
values
from
each
of
our
coil
separations.
It's
fairly
dead
here.
In
the
point
three
meter:
coil
separation
he's
starting
to
build
a
point.
Five
point.
A
This
is
one
point,
six
meters
of
depth
this
out
feature
here
with
we've
got
a
bit
of
a
high
conductor
at
the
end
there
and
there's
actually
a
road
that
goes
through
there,
which
is
essentially
a
fund,
a
lot
of
blood,
because
this
country's
all
always
on
the
water.
All
the
roads
are
up
two
minutes
off
quite
a
land
surface,
to
account
for
that.
So
essentially,
there's
a
big
dam
bank.
C
A
H
A
E
A
At
a
tenth
of
a
second,
so
it
averages
that
are
over
five
seconds
and
saves
the
output.
In
this
scenario,
this
is
one
second
dollar,
and
this
is
when
the
instrument
carried
along
on
the
go.
This
one
has
been
built
GPS
as
well,
and
that's
that's
all
standing
with
the
data,
so
this
walking
survey
was
conducted.
You
can
see
where
we
walked
for
this
one,
and
actually
that
slide.
I
showed
you
before
that
red
loop
is,
is
actually
part
of
that
of
that
largest
survey
area.
A
You
can
see,
there's
a
gap
in
the
data
there
and
that
comes
through
in
each
it's
just
creepy
across
that
gap,
but
the
reason
there's
a
gap.
There
is
because
it's
a
farm,
storage
jams
and
you
can
see
on
the
western
side
of
there's
a
bit
of
a
plume
coming
up
on
the
western
side
of
that
dam,
which
I
think
relates
to
water
leaking
out
of
that
or
the
overflow
path
of
that
bandwidth.
It
fills
off
down.
A
B
A
A
A
And
even
conductivity
space
throughout
that
crop
trial,
so
we
just
rent
the
conductances
and
braking.
We
think
we've
got
I'm.
The
d-10
sample
hulls
were
breaking
into
ten
that
even
come
back.
Tivity
lands
pick
those
points
and
then
yard
sample
those
points
for
one
of
the
coil
separations.
That's
how
we
sample
and
then
we
take
those
back
to
the
lab
and
do
one
the
five
and
soar
moisture
measurements
EC
measurements
that
meet
that
is,
but
I've
had
trouble,
trying
to
match
the
laboratory
data
to
the
actual
conductance
and
it
to
the
inferred
data
as
well.
A
A
The
top
call
separation-
that's
possibly
because
this
orb
was
being
extracted
by
the
plants,
it's
pretty
dry
and
pretty
dead
up
there
and
we're
not
getting
much
response,
which
is
probably
okay.
It's
probably
real,
but
I.
Think
I
probably
need
to
go
back
and
have
a
look
at
some
of
the
first
principles
that
we
looked
at
yesterday
and
look
at
some
of
the
things
like
skin
effect.
That
type
of
thing
I
think
the
whole
the
whole
predict
needs
a
bit
of
an
overhaul
in
survey.
D
A
A
This
is
the
R
squared
of
the
this
is
mesh
data
versus
modern
data
and
what
these
values
here
that
come
off
the
one,
the
one
fit
all
come
from
the
one
quarter
and
I'm
concerned
that
I
mean
to
a
pup,
the
the
conductance
in
that
coil
to
to
bring
that
line
up
there.
But
I
need
to
talk
to
the
company
about
that.
H
A
C
A
A
A
C
C
B
A
D
A
A
I,
don't
we
do
you
this,
that
the
it
works
on
the
theory
that
at
low
induction
numbers,
70%
of
the
conductance,
is
for
those
effective
deaths
about
upset
with
that
geometry?
That's
that's
the
theory.
Now,
if
you
go
and
there's
thresholds
in
them
in
the
manual
that
so
if
you
have
conductances
that
exceed
I,
don't
know
250
of
India's
the
lowest
on
one
of
the
core
separations.
If
you
exceed
250
you
better
off
converting
the
in
fades
back
to
use
that
value
want
to
exceed
because
you're
above
low
inductance.
H
A
H
I
That's
good.
The
other
thing
you'd
mentioned
that
all
we
need
to
look
at
things
like
skin
depth.
This,
that's
probably
not
given
them.
You
know
spent
little
conductance
values
here.
It's
probably
not
not
a
big
issue.
If
you
look
at
these
there's
a
typical
curve
that
can
pose
with
these
horizontal
systems,
so
that
the
response
is
like
a
characteristic
curve.
J
I
I
So
these
are
things
that
attempt
kind
of
then
help.
You
understand
like
how
I
how
I'm
going
from
the
type
curve
of
that
instrument
now
two
successive
greater
depths
of
penetration
and
then
the
fundamental
assumption
for
using
the
quadrature
ona
is
just
that.
The
skin
depth
that
you've
got
has
to
be
much
greater
than
here.
Separation
in
the
coils
right.
I
I
A
A
F
This
is
a
case
study.
I
was
working
on
a
few
months
ago,
Karen
barrini
within
the
button
fault
zone
in
competative,
so
this
area's
about
ten
kilometers
north
of
the
MacArthur
River
line,
and
so
what
we
had
over
this
area
is
we
had.
The
project
were
working
on.
We've
got
some
500
meter
space,
ground,
grotty
data
acquired
over
this
area,
and
we
had
some
B
temp
data
that
was
collected,
I,
think
in
2009,
which
some
of
my
colleagues
at
SAR
have
regretted.
So
we've
basically
taken
the
interpretation
from
the
grubby
dot.
F
I
did
some
property
modeling
and
compared
that
to
the
interpretation
of
the
nearly
30
M
data,
and
so
first
thing
that
I
did
here
was
basically
look
at
the
gravity
of
the
AEM
and
they're
ready
metrics
to
produce
a
solid
geological
map
of
the
area.
So
it's
not
very
deep,
there's
a
tiny
bit
of
cover,
so
we
had
some
our
craft
does
a
bit
of
existing
mapping
that
mths
did
so
I've,
basically
interpreted
the
gravity
and
AM
data
to
come
up
with
with
this
map
and
also
interpret
all
of
the
faults
that
climate.
F
F
So
let
me
see
that
in
in
my
gravity,
data
there
are
radiometric,
say,
m
and
all
the
even
at
a
large
scale
and
Magnotta
so
going
into
this
project.
We
had.
We
were
given
a
pre-need
implicit
model
that
was
built
a
few
years
ago,
based
on
some
structural
structural
data
and
some
drill,
hole,
constraints
and
I've,
taken
that
pattern
used
to
junior
constraint,
gravity
model
and
it
basically
all
I
did
here-
was
take
the
existing
model
and
find
out
where
the
problems
were
so
bring
it
down
into
this
straight
about
the
glaze
that
we
have.
F
We've
got
quite
crude
control
on
the
densities.
There's
a
lot
of
rough
repeat
measurements
throughout
the
whole
statements
of
them
complicate
it.
So
we
had
a
lot
of
control
of
that.
I've
done
is
taken
this
model
populated
it
with
AC
measurements.
He
printed
it
and
what
we
say
in
this
room
to
you
lay
out
where
we
getting
all
these
density.
You
normally
stand
up.
I
was
telling
me
that
there
was
a
structural
problem
with
that
part
of
the
model.
F
So,
look
at
that
so
I
looked
at
where
we're
getting
these
density
anomalies
within
the
model
and
compared
it
with
the
geological
map.
What
they're
saying
is
it
sort
of
confined
within
this
area
whence
of
the
evening
felt
and
bound
by
this
fault
that
we're
picking
up
in
the
PM
data
and
so
I
came
up
with
a
few
possible
interpretations
were
eating.
This
cutscene
normally
could
be
that
we're
getting
sediments
employed
by
any
probe.
F
F
F
This
is
just
a
couple
of
sections
that
that
we
had
so
we
have
a
drill
hole
through
this
readers
here
and
the
binding
Creek
Formation
is,
we
know
it's
the
white
conductive
and
the
marker
from
the
drill
hole
actually
intersects,
this
conductor
yeah.
So
we
know
here
controlling
that.
We
know
that's
funny.
Creek
Formation.
The
problem
is,
as
we
come
along
this
section,
then
we,
the
a.m.
data
splits
into
these
two
conductors-
and
we
don't
know
here
if
it's
a
deeper
one
or
if
it's
the
shallow
on.
F
If
this
is
another
formation
coming
in
or
if
we've
got
a
got
a
for,
this
could
be
a
sub
basin
along
here.
So
this
is
a
problem
we're
having.
Hopefully
in
the
next
few
months,
we'll
get
there'll
be
some
bit
of
drilling
out
there,
we'll
have
a
few
more
constraints,
and
then
we
can
come
back
and
update
this
model.
F
But
what
we
do
is
we
basically
came
up
with
three
different
two
interpretations
of
this
or
from
the
deep
and
chilling
conductor
and
once
I
compare
that
to
everything
big
density
anomaly.
So
this
is
just
a
section
through
that
what
we've
got
orders
are
award
dollars
day,
where
we
getting
this
busy,
you
normally
comparing
that
to
the
interpretation
of
the
deeper
cello
conductor,
so
this
is
just
showing
the
depth
to
the
top
of
the
conductive
anomaly
there.
So
this
is
another
day.
This
is
our
preferred
model,
because
a
big
conductor
is
actually
getting
quite
close.
F
We've
got
an
investigation.
We
don't
have
a
lot
of
confidence
in
that
interpretation,
but
we're
seeing
this
increase
in
depth
to
the
top
of
the
Bonnie
Creek
Formation.
Here
it
correlates
well
with
the
into
the
anomaly
that
we're
seeing
in
the
gravity
inversions.
So
we've
got
these
two
new
surfaces
that
we
then
put
into
a
new
3d
model.
Then
we
inverted
that
against
the
gravity
are
we
getting?
Actually
both
models
produce
a
much
better
fit
to
the
gravity.
F
Data
again
both
could
be
plausible,
but
this
is
our
preferred
model
and
it
also
fits
better
with
the
geological
data
we
had.
So
what
we
thought
this
could
be
is
is
a
sub
basin
adjacent
to
the
in
defaults
or
transnational
surface,
and
that's
what
we're
seeing
elsewhere
along
the
EMU
fault
as
well,
so
we
came
up
with
the
geological
model
model,
so
you've
got
these
transitional
sub
basins
again.
This
is
a
another
one
of
these
sub
basins
that
you're
seeing
further
to
the
south
in
the
battle
zone.
F
F
H

E
Hello,
everybody,
my
name
is
Julian
a
PCP
student
and
my
research
progress
is
three-dimensional
time
to
mend
our
ponk
electromagnetic
modeling
and
immigration,
so
it
is,
sounds
much
more
theoretical,
so
maybe
a
little
boring
but
I
will
go
faster
and
today
I'm
very
happy
having
this
chance
to
share
some
of
my
research
work
with
of
you.
So
maybe,
if
possible,
you
can't
give
me
some
suggestion
for
my
study.
Research
work.
E
E
As
we
all
know,
no
matter
for
the
Cemil
semi
airborne,
so
we
are
a
burn
service,
they
hope
produce
large
amounts
of
data.
So
in
the
Cask
of
authority
calculation,
the
time
and
memory
cost
are
almost
impractical.
So
conventional
imaging
and
one
thing
you
version-
are
the
best
choice.
But
in
recent
years
many
acceleration
techniques
have
been
proposed.
I
think
there
are
two
main
methods:
the
first
one
is
the
director.
E
The
director
use
the
young
calculation
presented
by
Professor
that
and
another
one
is
the
moving
footprint
proposed
by
Professor
Leif
Cox,
so
to
further
speed
up
to
further
speed
up
my
3d
calculation
I
adopt
our
field
separation
method.
Here,
I
use
a
half
space
while
they
are
the
earth
in
time,
domain
response,
I,
draw
primary
field
and
the
target,
or
normally
target
response
at
the
secretary
field.
E
E
You
know
much
smaller
area,
it
means
that
lie
stories
last
time
cost
and
the
second
one
is
I.
Don't
need
to
consider
a
singularity
problems
out
of
fast.
The
field
has
to
change
around
the
transmitters,
because
I
calculate
the
primary
field,
aware
semi
and
analytical
solution,
and
the
third
one
is.
The
primary
field
can
be
study.
Memory
for
reviews,
except
this
mattered-
I
also
adopt
the
local
mice
to
further
decrease
the
grit
number.
E
Here
the
total
field
method
means
I
directly
calculate
the
response
without
any
fuel
separation
and
the
transmitting
current
is
the
right
play
put
in
the
transmitter
loop
and
do
the
calculation.
So
I
can
compare
the
speed
this.
We
can
see
the
sphere
separation
method
is
much
faster
than
the
total
field
method
and
total
time
is
about
75%
replies.
It
means
if
this
measure
cost
one
hour.
Maybe
the
field
separation
method
just
needs
15
minutes
I
also
do
the.
E
I
E
And
so
that
this
is
the
step
transmitting
reform,
so
I
our
calculate
the
half
sign
transmitting
your
phone,
and
this
is
the
response
we
can
see.
Unconcerned
all
there
is
send
change.
What
the
interesting
is.
The
same,
change
in
place
is
responding
to
the
edge
of
this
target.
It's
200
meters
is
200
meters,
but
the
off
time
signal
is
much
smoother,
so
maybe
I
should
do
some
more
research
work
on
time.
E
H
G
Thank
you
today,
I'll
be
talked
about
it's
nice
different
Obachan
about
a
geomagnetic.
You
have
dependence
in
Australia,
so
all
my
talking
is
has
been
published
in
space
weather
in
December
2016.
If
we're
not
clear,
you
can
have
a
read
my
paper,
so
you
know
in
Australia
we
have
a
fully
connected
for
the
kinetic
electrical
grade
in
that
in
eastern
and
the
western
coast.
Also
we
have
our
significant
popular
networker
show
on
those
left.
So
it's
important
to
understand
that
geomagnetic
induced
occurrence,
because
I
think
consequence
of
our
power
problem
could
be
a
significant.
G
So
it's
all!
Well,
you
know
that
your
memory,
GRC
study,
will
be
using
divided
into
two
step,
is
rgvideos
women
and
and
unionist
episode
today.
I
will
just
talk
about
that
geophysical
data,
so
the
data
we
are
using
a
probe
is
caught
Austria.
Where
are
the
opportunities
stations?
That's
the
basic
size
about
the
275
kilometer,
so
us
I've,
broader
skills,
really
electrical
conductivity
model
was
derived
from
this
data
set.
The
data
was
collected
in
early
1990,
so
here
are
highlights
a
few
conductivity
map
at
a
different
than
the
absolute,
the
first,
the
first
one.
B
F
G
G
G
Okay,
this
model
is
called
ocean
and
accounting
air
model.
This
border
accounts
for
the
conductivity
contrast.
It
is
between
the
land
and
the
ocean,
and
no
reference
and
in
the
conductivity
are
normally
on
the
land,
so
we
can
see
in
the
center
Australia
here.
These
are
pretty
much
like
on
a
simple
model
shown
in
the
previous
slides,
other
or
Edessa
enhancements
in
the
fields
here
and
also
distortion
in
the
direction
of
a
caloric
effector
somewhere.
A
G
G
Okay,
this
is
a
slice.
Okay,
now
we
are
using
the
model.
We
have
tried,
derived
and
induced
electrical
currents.
First
of
all
we
are
doing.
Is
we
have
imagined
that
whether
the
Magna
theater
and
the
electrical
fields
in
the
central
thin
to
Australia
in
Allison-
and
it
is
pretty
magnetic
observatory-
and
we
calculated
that
response
the
tensor,
which
is
like
an
imperial
tensor,
then
we
recalculate
from
the
impeding
tensor
and
the
magnetic
field
will
do
calculated
times
use
of
electrical
fields.
G
You
can
see
these
are
different
between
the
estimated
with
our
measure,
the
certainly
they
are
very
good
because
we
are
coming
to
calculate
F
from
the
net.
Okay.
Now
we
are
using.
That
cannot
even
model
to
calculate
the
variance
one
strength
you
as
you're,
showing
the
thought
points
are
on
the
right
panel
and
because
the
conductivity
model
was
they
have
a
do.
Not
a
very
good
resolution
ever
see
redemption,
so
we
have
our
so
limited.
G
The
band
weighs
only
two
here
as
and,
as
you
say,
we
are
predicting
ready
and
Masuda
black,
as
are
some
difference,
especially
during
the
rapid
amenity
variation,
largely
difference.
This
is
because
the
response
who
finally
shut
off
with
a
leg
off
of
the
shoddy
elevator
in
there
okay-
so
this
is
probably
your
city-
means
a
vegan
so
now
every
so.
This
will
be
even
to
show
them
have
a
proposed
and
in
progress
and
completa
Austin
program
stations
are
we
Wednesday
those
Austin?
D
That's
what
we're
getting
started
from
Malkovich
anyway,
like
a
standard
and
yeah,
the
FGA
group.
It's
a
group
of
companies.
Three
companies
love
you
I.
Suppose
the
main
companies
actually
physics
Australia.
We
specialize
in
mineral
exploration,
helped
develop
another
one
sort
of
technologies,
always
velvety
the
same
technology.
For
example.
We.
A
D
B
D
Is
kept,
the
OD,
which
again
is
services,
come
and
get
some
a
partnership
with
big
buildings
and
pretty
water
geophysics.
So
we
specialize
in
unexploded
bomb
detection
or
they're
building
specialized
equipment
to
living
that
this
is
just
an
overview
of
the
Gabi
idea
of
suppose,
because
it
sort
of
shows
some
of
the
developments
have
happened
along
the
way
I've
got
involved
in
Mike's,
but
upon
detection
work
back
in
the
early
80s,
showing
wage.
D
This
gap,
EOD,
we
only
formed,
must
have
been
about
2013
I
think
we
do
D
from
a
little
bit
bitten
by
the
financial
crisis
back
in
the
only
mm,
but
but
anyway,
we've
since
zippy
formed
a
PID
we've
been
doing
the
OD
work.
You
can
explosive
ordnance
detection
work
number
of
projects,
we've
done
there,
desiccant
done
with
ultra
mag.
So
this
is
one
of
our
very
high
sampling,
mag
mag
systems,
quite
sensitive
racism,
papermania
dominance,
we've
been
working
the
pros
for
30
years
now.
D
Just
another
example
of
using
the
Marietta
Moga
former
Army
Depot's
in
Australia,
so
a
lot
of
fun,
former
military
sites
in
Australia
contaminated
with
bombs,
for
example.
So
it's
real
issue
to
actually
clean
those
up.
We've
been
using
magnetometers.
Historically,
we
didn't
have
access
to
put
en
transmitters
and
receivers
back
in
the
early
days.
E
D
And
a
CT
I
think
they
said.
I
won't
spend
too
much
time
on
this,
but
I
can
lose.
It
just
make
vague
responses
that
we're
seeing
from
one
protection
work.
You
can
see
that
they've
quite
clean
one
of
the
real
issues
with
using.
As
for
us,
our
courses
where
you've
got
a
letter,
a
textiles
tools
which
you
have
very
many
sometimes
quite
hard
to
actually
distinguish
individual.
You
look
so
calm
for
nominees,
so
you're,
obviously
very
high
resolution
surveys.
D
We've
got
sensors,
which
might
be
of
the
order
of
35
centimeters
apart
we're
taking
samples,
typically
reviews
for
the
five
centimeters
or
less
online,
and
so
very
high
resolution,
more
mag
surveys.
Typically,
you
know
this
is
actually
up
in
in
Queensland
the
Sunshine
Coast.
A
lot
of
the
Sunshine
Coast
was
uses
practice
bombing
brokers
from
chips
out
in
the
ocean,
which
at
least
you
can
pull
out
on
the
floor.
D
More
mag
surveys,
so
in
2013
we
started
14.
Rather
we
started
building
the
ultra
tempest
system,
so
this
is
instead
of
using
magnetometers.
Now
we
started
to
use
e/m
system,
so
we've
built
our
own
three
component
cubes.
So
these
cubes
here
are
actual
quarters,
they're
three
component
coils
and
we
use
those
with
them
in
an
array.
A
D
One
of
the
first
implementations,
I'll
disposals,
with
a
probably
look
like
that:
2014
I'm,
just
an
example
of
some
three-component
out
of
there,
my
short
component
that
is
sort
of
sustained
presentation,
so
I'm
living
with
another,
later
version
of
it.
So
it's
a
total
raid,
our
property
total
right
now,
we've
rebuilt
instrumentation
receiver
systems,
they're
sitting
on
the
factories
that
the
vehicle
here,
but
it's
not
too
dissimilar
to
what
what
Dave
does
register
different
scale,
because
totoro
system
with
the
conceited
would
have
been
a
tree
component.
Cubes
on
on
that.
D
Another
view
of
the
same
thing:
you're
suppose:
we've
done
one
of
the
largest
cubic,
so
VM
surveys
bleeding
town.
So
this
is
supposed
to
be
extending
down
air
base
for
bringing
in
the
new
jet
fighters,
but
yes,
I
very
contaminated,
and
all
these
are
items
of
Buick
so
and
platter,
and
everything
Steve
himself
is
those
specialists
and
discrimination.
He
actually
worked
with
these
Facebook
with
you
didn't,
go
I,
think
and
work
very
much
on
discrimination
ordinance
from
so.
D
Our
reason
for
that
is
to
get
very
high
quality
three
component
in
data
to
be
able
to
determine
what
scrap
what
tension
will
really
a
Buick.
So
so
it
makes
a
huge
difference
to
the
digging
costs
would
even
process
if
they
can
actually
reduce
the
amount
of
digging
of
a
discriminating
between
what's
real
giving.
So
that's
not.
D
D
This
is,
this
is
actually
using
the
operating
system
for
the
detection
of
case
I've
heard
that
terminology
before
G
T
stands
for
engaging
tools.
So
this
is
a
real
real
problem
in
some
of
the
mines
where
the
large
excavators,
large
Ripper
teeth
might
be,
might
fall
off
a
machine
if
you
like,
I
can
get
lost
in
the
stockpiles
and
the
big
issue
with
that
is.
D
If
they
go
through
the
crusher,
they
eventually
cause
a
lot
of
damage
to
the
crusher,
but,
secondly,
cause
significant
downtime,
so
you
might
have
a
week
of
a
crusher,
not
working
which
could
cost
cost
of
millions
of
dollars
into
these
mines
once
they're
in
full
production.
So
so,
basically,
this
is
an
amazing,
so
they
really
because
it's
actually
finding
items
of
get
steal
items
in
the
magnetite
software
so
but
actually
work
extremely
well.
D
D
There
are
just
more
examples
of
things
that
were
found
in
the
stockpiles:
we've
had
a
system
working
in
the
Ho
Chi
Minh
Trail,
basically
for
a
few
years
now.
This
is
for
the
galaxy
line
that's
upon,
but
we've
actually
released
systems
to
them.
So
they've
added
now
delivered
two
or
three
years
of
human.
The
crystal
at
the
time.
It's
been
working
very
successful.
You
know,
prior
to
going
over
there,
everything
was
just
done
with
analog
system,
so
there
was
no
record
of
what
was
found.
D
F
D
D
So
that's
actually
working
in
quite
well,
so
unless
at
the
moment
be
using
one
of
our
high
current
transmitters
geo
pack,
a
two
pack
actually
builds
the
transmitters
for
these
phones
as
well.
So
we
have
a
very
small
transmitter
which
I
can
show
you
photographed
more
later,
which
can
rights
up
to
about
200
amps,
relatively
small
bloop,
so
we
use
them
for
a
living.
Would
he
answer
those,
for
example,
as
well?
That's
what
they
originally
designed
for.
D
D
Smaller
examples,
alright
become
plastic
out
systems
doing
down
whole
again
in
Germany
as
well,
so
we've
been
working
with
a
company
they're
called
Heinrich,
hoodies
and
they're
responsible
for
actually
finding
in
our
large
bombs,
whichever
left
those
from
the
Second
World
War,
which
is
still
within
villages
for
example.
So
it's
what
can't
be
doing
spare
waste
between
ours.
You
know
in
places
like
that.
D
They're
just
another
example
of
them
to
digging
one
up:
it's
amazing
the
inversions
ago,
as
our
table
down
some
of
these,
these
sorts
of
items
this
particular
case
they
actually
model
it
as
being
two
items
similar
in
size,
I
think
to
the
mark,
84
that
it
actually
broken
in
half.
They
were
actually
actually
open
to
detect
the
two
parts
to
the
to
the
bottom.
D
D
Their
caustic
later
actually
yeah
I'm
talking
about
that.
It's
not
in
the
troubles
as
well,
so
we
just
done
some
more
work
terribly
in
Tehran,
as
well
with
the
optimum
system,
and
just
just
the
other
thing
to
mention
is
that
over
the
last
twelve
months,
I
suppose
we've
deployed
under
a
marine
system
a
marine
suffocating
system
which
has
been
operating
in
Portsmouth
Harbor.
So
it's
actually
a
number
of
different
transmitter
loops
several
loops,
which
are
firing
independently,
they're
all
array
of
the
three
components
of
those
sorry
coils
and
sensors
on
them.
D
F
D
So
this
is
I'm
gonna
put
a
little
bit
about
Sam
at
the
moment.
Don't
talk
about
a
heli
same
survey
before,
and
blog
talk
a
little
bit
about
the
reasons
for
developing
that
technique.
Chris
actually
talked
about
Sam
and
its
application
for
very
high
resolution,
shallow
earth
measurement,
and
in
fact
it
was
he
written
reason
and
I
develop
standards.
It
was
actually
the
subject
to
my
PhD
work
that
nineties,
but
well
going
back
to
even
before
that.
D
I
did
my
master's
degree
on
IP
back
in
the
early
eighties,
and
one
thing
I
was
looking
at
with
IP
was
just
how,
under
sampled,
the
electrical
fields
were
with
with
these
fairly
sparse
arrays,
if
you
like,
prior
to
that
I've
been
working
with
our
resolution,
link,
magnetics
and
I
put
two
and
two
together
and
thought.
Well,
if
I
can
actually
use
something
like
a
magnetometer
to
mention
electrical
responses
as
well
and
still
and
get
the
spatial
definition
with
electrical
fields,
a
big
achievement
would
be
quite
a
valuable
technique.
D
Hence
the
concept
Sam
was
born,
but
so
what
I
want
to
talk
about
here
is
not
just
not
the
high
resolution.
Applications
or
Sam,
but
in
fact,
that
application
for
deep
penetration
survey
says
well
or
which
dog
motion
so
basically
tend
to
think
that
the
mineral
exploration
we've
sort
of
bleed
a
bit
beyond
low
hanging
fruit.
We
found
the
easy
stuff.
You
know
the
memorization,
which
is
basically
what
is
it
find
near
surface
has
probably
already
been
found
I'm.
D
Suppose
I
hope
I'll
make
there
is
you
know
normally
many
covers
you've
got
pretty
tight
budgets
these
days,
so
you
really
want
to
get
the
maximum
figure.
Expiration
I
talked
about
viable
expiration
depths
here,
I
think
in
terms
of
viable
expiration
that
so
I'm
thinking
about
what
actually
my
normal,
you
know.
Typically,
the
top
climate
I
suppose
is
what
you'd
call
multiple
they've
been
finding
a
new
all
body
that
that
a
depth
below
that
chances
are
it's
going
to
require
too
much
cost
to
actually
get
down
at
the
mana.
The
engineer
expensive.
D
So
are
we
not
really
all
that
them
that
useful
and
really,
if
there
is
more
positive,
that
kind
of
depth
they're?
Not
not,
so
you
so
much
use
them?
It's
either
going
to
be
duped,
they've
gotta,
be
large.
The
shallow
expiration
and
I
got
call
zero
to
300
meters
and
they
kind
of
benefit
more
from
high
spatial
resolution.
That's
where
things
like
their
standard,
saying
a
resolution.
D
Conductivity
map
comes
in
and
and
other
techniques,
of
course,
the
deep
expiration
between
three
three
hundred
meters,
and
if
there
are
some
meters,
let's
say
you
get
most
basic
guidance
from
from
circuit
expression
for
geology.
You
get
further
away
from
the
surface.
You
know
basic
that
lots
of
paranormal
tips
so,
and
the
other
thing
I'll
point
out
is
that
the
deeper
the
old
body
you
can
mediate
responses,
the
longer
the
wavelength
so.
D
D
D
So,
if
you're
doing
deep
deep
penetration,
we
need
to
have
larger
scale
surveys.
We
need
to
have
greater
sensitivity,
because
the
signals
are
so
much
weak.
Now
you
need
to
have
a
lot
more
transmitter
power
between
the
many
years.
Of
course,
we
also
need
because
of
the
scale
of
the
surveys
being
so
much
larger,
but
they
have
much
more
efficient
acquisition,
otherwise
just
becomes
cost
prohibitive.
D
D
We
talked
about
Sam
a
little
bit
before
big.
Using
a
transmitter
can
be
either
a
dipole,
as
you
saw
with
Chris's
presentation,
we
can
actually
use
a
fixed
loop,
which
is
filled
with
bugs
presentation.
What
we
do
is
actually
we're
kind
of
using
the
Earth's
magnetic
field.
If
you
like,
it's
a
carrier
signal
and
we're
using
a
total
field,
Meghnath
on
mother
to
actually
acquire
data
about
the
Earth's
total
magnetic
field,
but
they
do
as
many
big
fields
got
a
modulation
sitting
on
top
of
them
to
do
the
transmitted
signal
response
of
the
earth.
D
So
what
we
do
is
basically
acquire
all
of
that
data
and
then
we
digitally
separated.
We
filter
it
off
separate
the
high
frequencies
from
the
Earth's
magnetic
field,
variations
due
to
convection
sort
of
processing
on
the
on
the
square
waves
to
get
through
eeehm
responses.
There
are
a
number
of
parameters
that
we
can
extract
from.
We
can
magnetics
applause
who's,
your
favorite
field
center,
we're
getting
further
field
magnetic
moving
the
electric
conductivity
of
its
entire
server
am
or
VoIP
as
well
types
of
survey
configurations
we
have.
D
This
is
kind
of
key
to
whites
and
words.
There
are
a
number
of
different
a.m.
stages
that
people
use
typically
for
doing
the
M
surveys,
coils,
pretty
common
flux,
gates,
we'll
talk
about
as
well
squid
through
an
excellent
sense
or
the
very
very
expansion
of
us
about
the
diversity
to
use
and,
of
course,
the
use
easier.
Vapor
is
the
one
that
we
use.
They
have
different
performance
characteristics
depending
upon
you
know.
D
The
frequencies
that
you're
looking
at
calls
are
better
at
at
higher
frequencies,
is
in
vapor
and
and
squid
from
a
better,
very
low
frequencies
at
Wrigley
Field
sensors.
So
if,
in
terms
of
deciding
what
senses
you're
using
for
a
particular
survey
need
to
sort
of
know
what
kind
of
conductances
font
constants
you're
looking
for,
but
high,
conductance
or
wattage,
which
is
what
I'm
talking
about
that,
they
will
then
maybe
be
field
centers,
as
opposed
to
be
defeatist
because
of
the
various
bouquets.
D
The
difference
between
one
of
those
senses
of
caesium
vapor
is
that
the
coil,
the
flux
coating,
has
quitted
all
vector
sensors
to
measure
the
changes
in
the
magnetic
field.
In
that
specific
direction,
specific
vector
the
difference
with
the
caesium
vapor
is
that
it
measures
variations
in
the
direction
of
the
Earth's
magnetic
field.
So
it's
a
total
field
sensor
from
a
application
point
of
view.
The
real
difference
there
is
that
there's
no
orientation
11
wide.
D
So
if
you're,
using
a
coil
or
a
flux,
gate
or
a
squid,
you've
got
a
level
that
you've
got
to
orient
it
and
you've
got
to
make
it
very
stable,
we'll
be
taking
a
measurement.
It's
not
the
case
for
the
cesium,
a
percentage,
because
it's
a
scalar
sensor
is
not
correctional
independent.
So
it
means
that
we
can
acquire
data.
What
we
continuously
moving
without
any
rotational
noise
through
the
movement
of
natural
sensor
itself,.
D
Sorry,
like
that,
all
that
stuff,
just
a
picture
of
the
mag
itself,
it's
a
it
actually
is
pretty
ugly
bits
very
high
precision
instrument
which
can
call
the
measuring
there's
magnetic
field.
That
rates
are
up
to
nearly
10
kilohertz.
So
for
a
total
field,
magnetometer
it
it's
a
very,
very
fast
and
quite
sophisticated
system.
D
D
A
UAV
system,
as
you
can
see
in
that
photo
there,
it
works
fine,
mr.
having
logistical
issues
for
that
with
navigation
software,
mainly
and
see
if
he
thinks
this
law
depakote
becomes
commercialized
if
we're
doing
extremely
sensitive
measurements,
for
a
big
search,
normally
we'll
use
Samson
mode,
which
is
the
stationary
measurements
or
acronyms.
D
So
in
this
particular
case
we
might
be
using
transmit
frequency.
You
195
verbs
would
be
typical,
big
five
meter,
sorry,
five
minute
readings
and
surveys
happening
with
the
moment
photographs.
There
was
a
Samson
system
working
in
Atacama,
Desert,
with
in
Finland
I
mean,
could
work
around
the
world
with
them.
D
The
other
thing
I
just
wanted
to
point
out
here
is
that
you
know
data
quality
depends
upon
a
number
of
factors
talking
about
cultural
nose
and
throat,
noise
and
operator
skill.
If
you've
got
an
active
source
like
you,
do
for
a
name
survey
or
not
needs
to
obey,
it's
not
just
the
sensitivity
of
receiver
that
matters.
It's
actually
that
the
strength
of
the
signal,
you're
transmitting
as
well.
So
one
thing
that
we
have
put
a
lot
of
effort
into
over
the
last
decade.
D
If
you
like
this,
building
very
iPad
power,
transmitters
with
big
penetration
or
power
quality
surveillance,
my
point
here
is
that
if
a
transmitter
system
isn't
powerful
enough
to
induce
the
response
from
the
contactor,
it
doesn't
matter
how
sensitive
your
receiver
is.
You
look
at
a
steer,
so
it
really
is
a
combination
of
transmitter
and
receiver
which
make
these
surveys
possible
and
the
effect
is
a
company
that
we
used
to
build
our
transmitters.
So
you
see
we
have
a
range
of
different
options
that
we
build.
There's
no
one
transmitted
at
several
applications.
D
D
Very
resistive
galvanic
dipoles,
you
own
high-voltage,
if
you,
if
your
Monday
yen,
you
look
like
current,
it's
very
difficult
to
build
all
these
things
into
one
transmitter.
If
you're
working
in
inaccessible
areas,
you
want
portability,
so
you
know,
depending
on
where
you're
working
you
need
be,
but
quite
different
requirements.
So
we've
got
a
range
of
transmitters
to
actually
soo-jung
continents
that
we
do.
This
is
the
latest
of
our
high-power
transmitters
called
the
hptx
ad,
and
if
any
of
you
familiar
with
doing
am
10
years
ago,
you
know
typically,
the
maximum
power
you
might.
E
D
Amps,
but
you
might
put
in
two
so
this
transmitter
is
capable
of
up
to
360
amps.
Typically,
if
we're
doing
down
whole
deep-penetration
town
I'll
surveys,
for
example,
we
might
be
operating
in
150
to
200
amp
range.
So
the
signal
with
those
ratios
that
we're
achieving
with
these
systems
are
kind
of
unprecedented.
You
know
if
it
really
has
revolutionized
the
quality
of
surveys.
We've
seen
in
the
industry.
D
If
you're
doing,
if
you
want
high
resolution,
sorry
high
voltage
survey
as
we
do
have
a
mobile
transmitter,
it's
a
portable
system
designed
to
be
slowly
to
places
it
neatly
before
access.
We've
learned
that
our
voltages
to
2500
points
there.
You
know
practical
constraints
and
safety
constraints
into
what
you
actually
use
interference,
but
also
something
we're
very
aware
of
is
limitations
might
be
from
a
safety
perspective.
D
Our
own
learning
lee
began
transmitters.
You
know
very
designed
to
be
portable
because
they're
moving
all
the
time.
So
in
this
case
we've
got
well
very
high,
currently
capable
up
to
200
amps,
but
there
you
can
see
they
can
fit
on
the
back
of
a
little
atv.
We
give
you
these
quite
easy
to
move
around.
Really.
D
We
talked
about
him
in
my
service
before.
If
talking
about
deep
penetration,
am
we
talked
about
the
theory
behind
I
just
wanted
to
show
you
a
little
bit
about
in
a
comparison
able
versus
branding
ham
surveys,
everyone.
D
A
great
tool
amazing
tool,
and
it
gives
us
the
ability
to
do
rapid,
thereby
coverage
over
large
areas
that
rather,
would
be
cheap
to
actually
deploy
for
the
area.
That's
covered
so
great
tool,
but
you
can't
always
be
limited
in
terms
of
the
depth
of
penetration
with
an
everyone's
system.
We've
get
after
this
original
for
that,
firstly,
typically
have
you've,
got
fairly
high,
transmit
frequencies,
I'm
talking
about
bonded,
much
arm
and
frequency
Lane,
so
typically
you've
got
rating
it.
Twenty
five
or
thirty
Hertz
so
you'd
occasion,
a
little
bit
to
roughly
ten
milliseconds
or
thereabouts.
D
D
Ground
level
VM
is
great.
We
have
much
lower
transmit
frequencies
to
get
better
depth
of
penetration.
The
ability
to
have
one
gas
station
occupation
on
so
better
quality
data,
because
we
can
stack
longer
and
you
could
hire
paint
me
to
power
than
possible
with
an
airborne
system,
because
we
can
have
the
ability
to
have
a
much
larger
generator
and
a
much
larger
loop
and
you
can
actually
deployed
from
the
helicopter,
but
there's
the
drawbacks.
D
Stationary
readings
are
needed,
so
it's
slow
and
it's
expensive
and,
of
course,
you
notice.
A
budget
constraints
always
always
Center
dictate
what
Ward
line
spacing
and
and
station
intervals.
So
what
I
commonly
sees
that
he
and
profiles
are
pretty
generally
understandable.
Typically,
four
hundred
me
to
talk
line
spacing
from
over
200
meters
at
least
we
might
so
again.
E
D
D
Doug
talked
a
fair
bit
about
that,
and
just
a
comparison
of
different
transmitted
configurations.
We've
talked
about
helicopter
ball
systems
typically
did
not
have
a
loop
of
20
to
35
meters
in
diameter.
Like
this
cod
kappa
v
tube
systems,
moving
loops
at
ground
level
might
be
usually
200.
Meters
by
200
meters
are
quite
common.
For
our
surveys.
Fixed
loops
can
be
much
larger.
They
can
be
on
the
bottom
or
even
wall.
D
If
you're
dealing
with
airborne
systems
in
current
state
generating
might
be
hundreds
of
ants,
you
know,
but
they're
actually
for
cutting
small
loop
ground
surveys.
Typically
with
up
has
always
been
sort
of
ten
to
forty
years
would
be
quite
common,
but
the
power
of
the
transmitter
system
is
called
the
dipole
moment
and
it's
the
dipole
moment,
which
really
gives
us
the
ability
to
get
depth
penetration.
D
Just
as
a
comparison,
I
know,
Doug
talked
about
from
skycam
system,
but
it
cool
your
figures,
modeling
from
two
thousand
and
six
or
seven
or
something
and
the
moments
they
were,
who
the
coating
of
the
order
of
about
point
two
million,
the
largest
SkyTeam
system
than
I,
was
scenes
but
I.
The
five
one
two
system
has
got
at
the
moment
of
about
3/4
of
a
meter
square,
the
highest
powered
one.
D
That
I'm
aware
of
it's
been
a
moment
about
two
million,
so
remember
that
no
home,
no
Minnesota,
so
it's
a
function
of
the
loop
size
as
well
as
the
current,
a
number
of
terms,
so
just
a
quick
comparison
of
dipole
moments
and
magnetic
flux
from
an
airborne
system
versus
ground
system
just
to
just
just
for
comparison,
not
just
put
a
model
the
plane
to
you.
Just
250
meter
supply
300
meter
plate,
it's
at
a
depth
of
500
meters,
just
a
little
bit
of
a
dip
right
at
30
degrees.
D
So
it's
got
a
plan
view
on
the
left-hand
side
and
they
and
the
view
from
the
south-
and
this
particular
case,
if
you
put
the
highest
paradigm
helicopter-borne
system
like
a
helicam
system
over
the
top
of
there
as
I.
So
it's
been
a
moment
of
two
million
and
the
helicopter
limb
is
actually
an
elevation
of
around
about
440
meters.
Then
the
flux
which
don't
was
talking
about
beginning
through
that
particular
played
at
that
depth
is
about
145,000
river.
D
So
if
you
compare
that
to
a
ground
system,
a
living
loop,
the
M
system
on
the
ground
with
exactly
the
same
moment,
two
million-
and
you
can
achieve
that
without
with
a
200
min
loop,
whether
it's
on
a
230,
for
example,
two
tones-
you
might
get
50
M
terrible
if
you
like
you
and
the
flux
goes
up
to
about
a
hundred
and
sixty
eight
thousand
and
the
reason
with
outages
that
the
loops
there
on
the
ground
there's
nothing
new
here.
So
this
is
just
purely
comparing
your
place.
D
You
go
to
a
larger
loop,
so
we've
got
a
400
meter
loop
now
with
exactly
the
same
transmitter,
the
limited
payoff.
So
current
goes
down
so
be
25,
amps
and
set
at
50,
but
the
loop
size
is
twice
in
both
directions.
Four
times
here,
yeah,
so
the
mic
moment
file,
not
the
full
million
the
fluxes
now
278,000.
D
So
the
flux
has
gone
up
a
fair
bit
with
exactly
the
same
transmitter,
same
power
and
the
transmitter,
but
with
the
larger
group,
so
the
penetration
is
very
dependent
upon
the
loop
style
is
obviously
not
going
to
have
a
400
middle
loop
under
helicopter.
You
know
that's
one
of
the
real
fact:
it
was
an
airborne
unit
system.
If
we
go
to
a.
B
D
Now
even
further
with
900
meter
loop
with
a
with
a
conventional
transmitter,
you
can
generate
a
moment
of
a
million
that's
with
a
conventional
transmitted
with
with
40
amps,
a
high-powered
transmitter
and
probably
four
times
at
so.
The
flux
has
now
gone
up
to
before,
leaving
obviously
the
larger
the
loop
them
all
power.
You've
got
the
greater
your
dipole,
no
more
change
eventually
got
of
I'm
getting
a
response
and
using
responsible
conductor
there
and
this
finally
I
figured
sleepy
em
system,
a
thousand
five
thousand
meters
with
a
conventional
plant.
D
D
G
D
I've
done
nothing
to
go
to
too
much
more
detail
here,
I
suppose,
because
I've
already
shown
you
the
lower
example,
but
we
have
a
couple
of
case
studies,
moments
from
the
forest
own
test
range
and
Western
Australia,
where
we
actually
compare
Sam
in
a
moving
acquisition.
Only
acquisition
notes
non-stop,
recording
over
and
a
couple
of
known
conductors,
we've
compared
that
with
stationary
greetings
with
Sampson.
D
D
Seen
with
everyone
he
emits
detectable
level
and
I
are
for
is
not
undetectable
if
they
have
only
images
closer
to
400
meters,
350
400
meters
down,
but
it's
actually
much
bigger
that
done.
We
put
a
cup
of
loops
around
each
one
of
these
l1.
The
is
around
IR
to
this
more
on
l2
is
really
our
fault
and
we
surveyed
it
with
Sam
in
both
banana
acquisition
mode
in
absentia
and
stationing
moment
for
different
frequencies.
D
This
is
Sampson
mode
and
I
just
point
out
that
what
we're
using
now
to
be
kick
seventies
on
to
my
climate,
Luke
150
amps,
showing
a
lot
of
power,
but
the
noise
level,
as
you
can
see,
they
were
open
to
achieve
by
the
ground
server
like
that
of
the
order
of
point
zero.
Zero.
Five
big
offensive
play
what
incredibly
small
always.
D
This
is
actually
the
profiles
a
koala,
dynamically
boosts
and
as
it's
without
even
stopping
to
take
a
measurement.
So
look
just
a
run
forward
a
little
bit.
This
is
a
response
from
Samsung
which
at
twenty
five
is.
This
is
a
response
from
Sam.
We
could
cover
a
lot
more
ground
because
not
stopping
to
take
the
measurement.
So
it's
very,
very
quick.
D
D
Twenty
five
problems
of
surveilling
in
one
day
and
said:
I
am
mode,
but
you
know
obviously
nothing
to
miss
that
that
response
all
other
and
that's
that's
from
a
conductor
which
is
400
litres
down,
so
comparison
cost
wise
or
the
forces
is
quite
significant
as
well
a
couple
of
days
of
surveying
compared
to
stationary
measurements.
Typically
something
like
that.
But
anyway,.
B
D
It
starts
very
deep
9600
liters,
Anabella
Andromeda,
so
very
big
balloon
Nonnie
the
survey
in
two
hours
to
do
that
on
their
crown
level
in
a
place
like
Canada.
First
of
all,
that
have
to
do
it
in
winter
when
everything
is
frozen,
because
under
Lake
I
think
they
had
to
clear
all
the
lines
to
actually
get
their
instruments
in
there
to
actually
do
the
acquisition
in
the
first
place.
D
Thing
about
this,
and
it
comes
back
to
what
also
Doug
was
talking
about-
is
that
we
didn't
have
one
of
our
high
power
transmitters.
Did
we
just
feel
so
hopeful
romantics
transmitter?
So
the
loop
was
about
1.7,
the
1.7
k's,
that
only
I
want
to
get
about
20
years
interval.
For
this
response
we
generated
from
only
20
amps
using
conventional,
a
little
dimensional
loop,
but
again
the
loops
always
meant
that
we've
got
a
moment
of
fifty
seven
million
compared
to
an
airport
system.
So
this.
D
As
we
pointed
out
the
other
day,
just
actually
apparel
on
its
runs
adjacent
to
the
loop,
so
that
the
power
one
was
reserved
basically
circuit
set
up
with
the
steel,
poles
and
lighting
circuits
and
things
in
it,
but
so
acted
like
a
really
nice
conductor
and
every
time,
obviously,
as
you
step
through
time,
the
the
response
from
the
power
line
dissipates
and
the
response
from
lane
law
shows
up
and
again,
this
is
similar
than
our
first
as
opposed
to
25.
So
we've
got
much
longer
decay
times
compared
to
conventional
net1
iam
system
as
well.

So,
whatever
like
to
show
now,
it's
open
source
resources
that
we
have
I'll,
show
you
how
to
use
them
and
also
where
you
can
jump
in
get
in
call
if
you're
interested
in
contributing
content
or
to
code
or
using
code,
there's
room
for
all
of
those
things
so
start
from
chief
saikhan
instead
so
introduce
this
briefly.
Yesterday
came
back
through
en
it's
the
main
resource
using
who's
been
textbook
for.
J
F
K
E
K
K
K
K
Got
the
blueprint
on
we've
got
an
inversion
from
do
a
one,
D
staff
conversion,
and
we
also
have
fun
morality
or
what
the
inversion
of
both
the
Skycam
and
the
result
guidance.
You
can
see
the
frequency
versus
time
too
many
versions,
hello,
setup,
works
and
senpai.
All
of
that,
and
so
those
are
three
downloaded
music.
You
like.
K
Another
thing
to
head
up
here:
is
it's
not
actually
just
specific
to
electromagnetics.
We've
got
other
methods
in
here
as
well,
I
mean
the
goal.
Is
this
Tim
pay?
It
becomes
a
place
where
seemingly
aiming
for
any
type
of
geophysical
data,
we've
got
potential
field
about
gravity
and
magnetics
t-series
acidity.
There's
some
IP
in
there
we've
got
frequency
domain
and
high
demand
as
I've
mentioned,
and
that.
K
K
K
J
K
Addicted
to
you
have
accepted
me,
and
just
we
looked
through
the
PM
apps
yesterday,
the
student
ones
worried
about
the
slide
bar
setup.
Obviously,
if
you
just
go
ahead
and
you're,
probably
super
pink
overdriving
came
from
a
beauty,
but
the
other
set
of
notebooks
that
we
have
actually
exposed
all
the
code,
and
so
that's
what
I'd
like
to
go
into
today
and
so
really.
What
we're
trying
to
accomplish
here
is
yeah
to
give.
K
K
K
Access
publication
that
the
SVG
does
and
it's
organized
by
Matt
Hall,
and
so
it's
you've
got
short
articles
and
then
it's
also
a
set
of
two
pair
notebooks.
They
go
along
with
it,
and
so
the
goal
is
to
be
able
to
actually
get
up
and
rush
with
whatever
tutorial
contents.
What
do
you
have
there
and
so
that
this
is
three
buds?
A
suite
of
notebooks
here,
so
there's
five
five
of
these
notebooks,
so
I'm
just
going
to
quickly
go
through
the
first
one.
K
J
B
B
K
K
K
K
J
K
F
K
K
A
batch,
then
we
have
all
of
the
finite
volume
operators
say
you
can
actually
insert
too
much
and
then
have
all
the
tools
use,
those
just
some
handy
utilities
and
then
install
very
plugins.
So
the
piece
of
solvers
is
if
some
good
ones
do
Python
and
then
they
also
help
just
interface.
It's
not
there's
a
parity
so
and
then
I
mapped
all
interested
plug
so
bring
all
those
in
here
I'm
just
going
to
flow
through
this
pretty.
But
maybe
we
won't
go
through
in
detail.
What's.
K
K
All
those
details
are
here
so
I
will
go
through
a
detail
is
that
you
know
3:00
3:15
on
computers
a
bit
much
so
once
we
actually
have
the
the
system
we
set
up
a
mesh
make
sure
it
goes
far
enough,
so
that
we
accept
Ascari
or
skin
depth,
and
also
that
we
have
fine
enough
cells
that
were
really
capturing
those
high
frequencies
and
then
from
there.
What
we
do
is
go
ahead
and
once
we
bought
the
mesh,
we
can
set
up
our
system.
So
here
you
see
that
we've
got
you
know
a
brad.
K
K
J
K
H
I
K
K
K
K
K
I
wish
I'll,
give
you
this
and
that
based
on
your
productivity
today,
to
give
it
so
when
you
want
to
determine
how
far
or
sorry
how
small
your
small
and
that
fits,
what
you
want
to
look
at
this,
basically,
how
quickly
for
the
few
exchanging
in
my
most
conductivity
men.
So
in
that
case,
you
need
to
consider
your
most
cannot
give
union
and
the
highest
frequency,
and
so
here
when
we
do
that,
we
look
at
our
base.
This
is
one
conductivity
and
our
highest
frequency,
and
we
see
that
our
minimums
can.
K
Therefore,
this
five
years
and
our
maximum
see
there.
It
is
what
what
six
times
in
the
pot
so
when
we
then
want
to
actually
go
ahead
and
design
a
match
that
we
can
use
for
simulating
on
this.
We
want
to
make
sure
that
our
smallest
cell
sizes,
so
that's
gonna,
you
can
hear
for
shorthand-
is
CX
in
cell
size.
K
Is
we've
got
a
few
cells
that
go
across
that
minimum
skin
s,
so
in
this
case,
I
want
to
make
sure
we've
got
more,
and
then
we
want
to
make
sure
that
we've
got
our
region
of
interest
sufficiently
match.
So
if
we
want
to
look
down
to
five
kilometers,
let's
just
have
uniform
mesh
under
there
and
then
we'll
expand
it
off.
So
we
can
open
it
on
up
and
see
okay,
so
our
smallest
cell
size,
125
meters.
K
So
what
we'll
do
is
actually
use
those
parameters
to
go
ahead
and
then
set
up
the
mesh
that
does
go
far
enough
and
satisfy
those
assumptions.
So
that's
what
we
can
hear
this.
We
just
have
a
little
script
there,
a
little
while
loop.
That
basically
says
if
I
have
any,
probably
far
enough
on
another
project
zone,
and
so
we
and
then
stop
once
you've
hit
that
threshold
37
Tuesday
tips.
So.
K
So
then,
from
there
now
that
we
have
all
them
extra
parameters
set
for
actually
going
to
create
a
mesh
object,
and
so
this
guy
here
we've
got
our
number
of
cells
in
the
core
region.
We
know
what
our
cell
spacing
should
be.
So
this
is
just
that
padding
region,
and
this
is
the
core
region,
and
then
we
can
go
ahead
and
construct
a
tensor
lunch
I'm.
So
in
this
case,
I'll
show
you
the
women.
Are
this
being
an
object?
K
K
K
K
K
K
So
we
just
go
up
and
block
the
mesh,
we'll
have
a
look
at
it
and
so
there's
sort
of
two
things
to
consider
where
we
can
place
things
on
this
actually
hug
notes
when
we
have
cell
centers.
So
that's
what
we're
highlighting
here
and
because
it's
just
one
of
the
mesh,
it's
just
a
line
all
right.
So
now
that
we
have
our
mesh,
we
can
go
ahead
and
put
our
model
on
device
and
so
we're
going
to
find
a
conductivity
value
at
every
cell
center.
J
K
So
here
to
make
things
a
little
more
interesting,
we'll
add
a
target,
so
you've
got
a
target.
Let's
go
reduces
to
a
few
1000
years.
We're
gonna!
Stick
it
a
depth
of
2
kilometers,
make
it
a
longer
time
so
then,
to
go
ahead
and
actually
set
up
our
conductivity
model.
We
started
their
hospitality
with
the
same
number
of
cells
right.
We
need
to
come
in
to
evaluate
every
single
cell,
how
we
find
out
where
our
lair
is
so.
This
is
just
saying:
I've
got
all
centers.
K
Make
sure
that
we're
looking
above
my
that's
like
being
that
dr.
Chynn,
there's
gonna,
grab
us
into
scenes
and
then
stick
the
target.
Car
is
gonna,
be
there
and
then
to
make
sure
that
what
we've
done
actually
make
sense
if
you
just
want
to
have
to
look
at
it.
So
we've
got
our
background
here.
We've
got
our
layer
that
starts
at
2
kilometers
depth.
It
goes
for
a
water
and
we're
back
to
a
smooth,
okay.
K
K
K
Okay-
and
so
in
this
case,
what
we've
done,
we
put
the
numeric,
which
is
the
one
that
is
so
many
using
a
finite
difference
approach
with
the
analytic.
You
can
see
we're
doing
a
pretty
good
job
and
one
of
the
things
that
you
might
want
to
look
at
at
this
point
in
this.
So
we've
got
confidence
now
that
our
code
is
doing
what
it
should
be
doing,
we're
going
to
match
mentally
and
independently
Telep
solution,
but
now
we
can
actually
go
ahead
and
ask
something
slip.
What
happens
is
we've
cleared
our
mesh
parameters?
K
K
J
J
B
J
K
K
K
K
If
you
have
a
look
at
the
results
data,
you
see
that
these
are
pretty
similar
and
although
we
can
definitely
tell
them,
there
is
a
conductive
layer
right.
We
do
see
that
showing
up
but
spread
between
these
three
small
you'd
be
hard-pressed
to
be
able
to
tell
the
difference
between
any
of
these
and
really
show
that
this
is
actually.
This
is
deep
in
right
and
if
you
have
to
go
up
to
feel,
we
of
course
know
that
you
always
have
sources
in
place,
so
you
can
add
a
little
bit
of
noise.
F
K
K
K
H
I
K
J
K
K
K
Gonna
bring
in
and
actually
implement
in
America,
and
so
this
is
the
way
that
we
have
broken
down
for
examination
of
sanik
inverse
problems
in
same
thing,
and
each
of
these
boxes
is
its
own
object
and
select.
But
I've
showed
you
before
it's
a
module
and
then
you
can
fold
it
up
and
custom
methods
in
properties,
and
this
is
the
same
across
all
the
Geo
methods
that
we've
implemented
instant
payment.
So
we
talked
about.
K
When
you
set
up
a
forward
simulation,
we
break
it
into
two
parts.
So
the
survey
contains
all
of
the
parameters
about
how
you
are
excited
in
the
system
and
how
you
are
measuring
data.
It's
all
your
geometries
there
and
then
what
fields
you're
listening
to
the
problem
is
actually
the
statement
of
physics.
So
what
are
we
gonna
solve?
Is
it
frequency
domain?
Is
it
time
domain
or
is
excited,
so
we
then
need
to
pair
the
thickness.
K
Play
with
the
approach,
so
we
combine
those
things
in
the
statement
of
an
inverse
problem,
which
is
an
optimization.
What
a
minimize
our
objective
function
subject
to
attend
shoes
we
plug
in
an
optimization
routines
appropriate
for
that
and
then,
if
you
go
ahead
and
solve
the
inversion,
that's
the
very
high
level
over
here
and
we'll
walk
through
that
in
this.
Don't
work
here
all
right!
So
look
at
our
packages
all
set
up
again
so.
K
F
C
K
F
B
K
Okay,
so
we
bringing
all
of
our
packages
and
now
we're
going
to
go
ahead
and
set
up
a
model.
So
here
we're
going
to
use
a
5/8
column
and
all
I've
done
is
defined.
Where
are
the
tops
of
each
of
the
layers
and
what
are
their
existed
so
in
a
lot
of
ways,
cos
mimics
a
bit
of
a
typical
structure
for
what
you
think
of
a
geothermal
system.
So.
K
A
resistor
overburden,
then
we've
got
a
conductive
and
perhaps
a
more
resistant
port
and
there's
some
connected
units
Beneatha
and
then
here
we're
defining
them.
The
same
frequency
range
is
what
we
used
in
the
last
example
I
in
this
case
we're
going
to
set
up
our
receivers
and
our
receivers,
our
impedance
measurements.
So.
K
And
so
this
is
that
survey
that
I
mentioned
before
same
as
the
last
notebook,
where
we're
gonna
set
up
a
mesh
that
is
appropriate
for
the
problem,
so
in
this
case
this
set
match
method.
This
is
something
that
we
wrote
three
empty
problems
that
just
that's
an
appropriate
match
based
on
heuristics,
we
developed
last
notebook
stocks
for
estimating,
and
then
we
can
go
ahead
and
look
at
it
and
make
sure
that
is
actually
a
reasonable
fashion.
What
we're
after.
K
Here
we're
setting
up
the
problem,
so
we
have
our
one
EMT
column.
It
takes
a
match
and
that's
because
the
problem
needs
to
know
how
to
actually
solve
the
physics
right
and
because
the
match
has
all
those
operators
and
you
set
that
up
with
coal.
We
then
actually
have
a
physics
engine,
there's
a
lot
of
details
on
what
we've
called
Mack
Danny's
name.
So
hey
radio
seemed
a
fairly
simple
one
here,
and
what
these
are
is
often
you
don't
actually
want
to
invert
for
the
physical
property,
the
true
physical
property,
we're.
K
K
Conductivity
varies:
we
do
have
a
logarithmic
scale
for
it.
So
that's
the
space
in
which
we
want
to
search
for
a
model.
If
you
were
to
go
to
3d
here
in
one
piece
community
in
the
air,
for
example,
you
might
want
to
consider
having
an
active
cell
map
so
there's
a
whole
bunch
of
examples
and
documentation
on
how
you
can
use
these
in
the.
K
K
B
K
F
K
E
K
K
Basically
the
inversion
set
up
in
a
little
function,
so
you
can
go
ahead
and
provided
recall
that
serving
here
we
can
provide
our
starting
off
our
reference
model.
Then
there's
a
couple
regularization
parameters
that
need
to
be
considered.
So
we've
got
what
we're
calling
alpha
s
and
alpha
said
so
our
smallness
week
and
our
smoothness
weight,
and
so
what
these
are
is
in
the
regularization
we're
considering
a
classic
team,
op
style
regularization,
so
they're
gonna
be
spread
under
with
what
a
smallness
versus
a
smoothness
term
of
a
buddy.
H
K
H
B
K
K
K
K
Other
things
that
we
have
in
here
you
can
play
with
is
what
are
we
want
to
use
for
a
starting
beta
and
then,
if
we
want
to
actually
sort
of
cool
beta
during
the
immersion,
so
start
with
a
high
weight
on
our
regularization
and
say:
let's
try
and
get
something.
That's
very
good.
A
smooth,
very
well
behaved
and
slowly
progressed
to
you
something
that's
fitting
our
deal.
K
K
K
K
K
K
B
J
B
E
B
C
K
K
K
K
K
What
she
said
there
is
when
we
increase
the
data,
what
we're
doing
any
more
emphasis
on
finding
fire
and
we're
caring
less
about
money,
and
so,
in
that
case,
what
you
use.
We
decrease
then
find
the
inversion
we'll
do
a
good
job,
fitting
buying
and
not
so
much
on
money,
whereas
if
we
decrease
back
together.
K
K
K
K
B
K
The
the
model
or
working
the
determine,
if
it's
possibly
one
an
example
where
we're
overfitting,
so
we
really
do
see
that
there's
a
lot
of
artificial
structure
coming
in
it's
dangerous
to
see
that
you
know
we
found
another
later
that
came
in
here
and
then
the
under
fit
example.
We
showed
you
know
there
are
five
layers,
but
we
can
get
more
out
of
the
inversion
still
on
five
stage.
K
Okay,
so
now
I'm
coming
back
to
one
of
the
original
questions
about
the
regularization
practice.
So
here
what
we're
going
to
do
is
run
around
the
movement
version
or
our
own
smaller
version.
So
in
one
case,
we're
going
to
have
this
moving
rootedness
methyl
larger
office.
So
we're
really
turning
down
the
volume
on
that
smallness
term.
We're
saying
give
us
and
then
we
do
the
reverse,
the
other
one
and
so
which
models
got
more
structure.
K

K
K

This
small
model,
because
we
really
asked
it
to
try
and
fit
the
reference
model
I-
was
telling
you
it's
gonna,
try
it's
best
to
to
put
tell
you
say,
and
it's
been
trying
to
sort
minimize
how
many
other
values
are
away
from
right,
and
so,
in
this
case,
it's
much
easier
to
introduce
more
structure,
I'm,
seeing
most
of
the
values
right
around
our
reference
model,
and
so
we
do
go
ahead
and
introduce
this
extra.
It's
quite
be
structure
because
we
have
not
asked
for
this
long.
K
K
I
I
H
K
K
No
I
mean
a
reference
model
is
a
is
a
good
way
to
introduce
them
a
priori
information.
If
you
do
know
that
those
layers
are
there,
you're,
not
necessarily
harming
yourself,
okay,
but
it's
important
to
remember
you,
don't
necessarily
want
to
sacrifice
things
like
smoothness
and
try
and
put
all
of
your
weight
onto
a
record.
I
I
Seeing
here
you're
likely
not
seeing
that
deep
and
then
you
might
be
suspicious
because
you
put
a
high
weight
on
trying
to
make
things
as
close
as
possible
to
a
100
over
2.01
series
premiere
that
okay,
maybe
maybe
I,
don't
really
have
the
right
to
background
model
and
maybe
that's
what's
causing
those
it's
like.
So
at
that
point
you
might
say:
well,
let's
demon
forget
about
having
a
smallness
term
month.
Maybe
this
could
be
run
without
a
small
concern
and
then
you
just
basically
looking
for
something
smooth
and
then
you
get
this.
I
And
Ron's
comment,
I
think
is
a
hundred
percent
right,
which
is
generally
what
what
we
do
is
just
kind
of
run.
This
aim
through
you're,
probably
overfitting,
is
we've
got
lots
of
structure,
but
you
cannot
rely
on
over
an
hour
or
any
algorithms
tell
you
which
one
to
choose.
Ultimately,
this
has
to
be
a
decision
that's
made
by
you
on
the
basis
of
whatever
information
you
thought.
So
you
look
at
something.
I
H
I
H
B
I
Know
those
might
start
to
be
pretty
subjective
decisions,
but,
as
men
see
said
here,
you
definitely
know
like
okay,
I'm
I'm
getting
much
more
reduced
misfit.
And
then,
if
you
look
for
your
I
guess
we
don't
have
them
long,
objective
Valley.
But
if
you
look
at
your
get
your
model
norm
down
here,
it
would
still
be
not
increasing
very
much,
but
then
you
know
as
you're
turning
the
corner.
I
Well,
sir,
your
your
mom
starts
to
increase
a
lot
as
you're
as
you
go
down
here,
so
you
don't
really
have
very
much
incremental
change
in
the
misfit,
so
here
you're
here
you're
getting
the
big
bang
for
your
buck.
His
far
as
not
very
much
change
in
your
overall
structure
compared
to
a
big
decrease
in
your
misfit,
whereas
here
you're
just
putting
in
much
more
structure
you're,
not
really!

And
so
with
with
cific,
these
are
one
people
versions
that
were
playing
around
with.
If
you
actually
want
to
go
in
to
set
up
things
that
are
larger
scale
treatment,
there
is
a
sheet
to
do
that.
It's
still
sort
of
acting
more
research
level
like
bringing
a
new
vertical
urges
we're
not
there
yet,
but
certainly
open
to
contributions,
and
if
there
are
people
who
are
interested
in
making
that
happen,
please
do
get
attached.
There's.

I

The
most
important
thing
for
the
point
of
view
of
getting
out
something,
that's
useless
where
you
put
in
your
eight
priority
information.
So
your
verify
our
information
may
not
very
much,
but
maybe
it's
tax
base,
but
maybe
it's
more
stuff
like
that.
So
all
of
that
work
that
goes
into
building
up
the
reference
models
and
stuff
and
and
what
you
think
you
know,
and
how
do
you
want
to
tailor
the
regularization
function
that
should
all
be
done?
I
But
after
beginning,
when
you're
really
thinking
about
what
you're
trying
you
know
and
then
what
do
I
have
constraints
while
I've
got
you
know
block
this
right.
Oh
I've
got
some
data,
that's
a
few
visible
data,
so
you
can
actually
think
about
the
most
important
part
of
this
inference,
problem
being
driven
by
they
once
you're
performing
this
regularization
functions.
So
it's
really
important
to
know
and
then
of
course,
then
you
want
to
bring
in
two
days.
You
want
to
make
sure
you
don't
don't
underestimate
the
power.
Yes.
K
I
Things
do
and
that's
problem
by
problem
dependent,
usually
kind
of
thinking
of
Florida
percentages.
The
first
guess
through,
but
those
are
the
two
things
are
the
two
things
that
really
determine
the
quality.
Also,
what
is
my
definition
or
my
misfit
and
the
numbers
that
are
going
in
what's
my
definition,
my
regularization
functional
and
letter,
the
numbers
that
are
going
to
require
a
lot
of
time
to
get
that
right.
