The
Antarctic
ice
sheet
changes
in
size
over
the
course
of
a
year.
When
it
is
summer
in
the
southern
hemisphere,
the
ice
sheet
decreases
in
size.
As
the
ice
sheet
melts,
it
releases
fresh
water
into
the
ocean.
In
the
southern
winter
(our
summer),
the
ice
refreezes,
drawing
fresh
water
out
of
the
surrounding
ocean,
leaving
the
salt
behind.
These
seasonal
changes
in
the
ice
sheet
are
examined
in
this

In
this
exercise,
students
observe
simulations
of
melting
sea
ice
and
a
melting
continental
ice
sheet
in
order
to
investigate
the
relationship
between
the
melting
of
the
ice
and
the
water
level
in
the
tank.
The
water
tanks
simulate
the
world
oceans.
In
the
first
example,
the
ice
is
floating
in
water.
This
would
be
an
example
of
icebergs
or
Arctic
ice
floating
on
the
ocean.
In
the
second

This
interactive
resource
portrays
what
might
happen
to
world
coastlines
if
entire
sections
of
the
Antarctic
Ice
Sheet
were
to
melt.
Viewers
can
see
how
much
land
area
might
be
flooded
by
a
relatively
modest
17-foot
rise
in
sea
level
(represented
by
the
collapse
of
the
Western
Antarctic
Ice
Sheet),
or
a
more
severe
170-foot
rise,
represented
by
the
collapse
of
the
Eastern
Antarctic
Ice
Sheet.

In this lesson, learners use WebImage, a Web-based customized version of ImageJ, to investigate changes in snow cover and sea ice in the Northern Hemisphere over a period of 24 years. The images are obtained from satellite measurements of visible and microwave radiation. The lesson follows from Snow and Ice: A Hemispherical View.

This
guide

provides
information
on
how
to
use
data
from

cores
in
the
classroom.
The
data

of
atmospheric
gas
percentages,
such
as
CO2,
in
fossil
air
bubbles
trapped
in
ice
cores
taken
at
the
Vostok
research
station
near
the
center
of
the
Antarctic
ice
sheet.
The
data
provides
an

In this lesson, learners compare snow and ice cover in the Northern Hemisphere over a period of two years. The images are obtained from measurements of visible and microwave radiation taken by satellites and sent back to Earth and are analyzed with a customized version of ImageJ running as an applet within a browser.

In
this
chapter,
using
My
World
GIS,
users
explore
data
that
characterize
the
dynamic
Greenland
Ice
Sheet.
By
examining
photographs,
map
views,
and
tabular
data,
users
gain
an
understanding
of
how
and
why
scientists
are
monitoring
the
ice
sheet
and
what
they
are
finding.
Users
explore
map
layers
that
represent
ice
sheet
thickness,
weather
station
locations,
and
annual

extents
of
the
