Radarsat Maps Slow Motion White Water Rivers

Synopsis:  Recent observations by a NASA-launched Canadian
spacecraft called Radarsat are giving scientists a remarkable view
of two fascinating features of Antarctica1s landscape.  Over a 24-
day period, the satellite captured new images of the frozen
continent, providing dramatic new data sets for researchers to
consider.  NASA's study of Antarctica is part of the Agency's
Earth Science Enterprise, a dedicated effort to better understand
how natural and human-induced changes affect our Earth's
environmental system.


ITEM 2a - LOCATING STREAMS ON THE ANTARCTIC CONTINENT-----TRT  :28

Over a 24-day span, scientists used two images over identical
regions of Antarctica in a technique called interferometry.  Their
comparative analysis of the images helped develop the following
ice stream animations on the west side of the continent, showing
flow rate and direction to an extent never before possible.


ITEM 2b - VECTOR ANALYSIS OF FLOW-------------------------TRT 1:15

In this visualization, longer black lines indicate a faster rate
of flow than shorter lines.  The fastest ice streams can move 400
to 500 meters a year, a blazing speed compared to tributary speeds
of little more than 10 meters a year.  Experts say the new
information can help describe large scale changes to the Antarctic
environment, as well as historical models about geological change.


ITEM 2c - FALSE COLOR ILLUSTRATION OF FLOW----------------TRT  :49

False color data derived from the Radarsat interferometry helps
illustrate the areas of the streams moving at different rates.
Reds indicate areas of greatest speed, while greens and blues are
slower.


ITEM 2d - SNOWDUNES--------------------------------------TRT   :23

Radarsat also enabled researchers to gain a better understanding
about a surface feature found only at the bottom of the world.
These snow dunes are believed to be highly stable waves of graded
ice grains, nearly impossible to see without the aid of satellite
remote sensing systems, and larger than the state of California.
Stretching for hundreds of kilometers, these dunes rise only 2 to
3 meters but may have a periodicity of more than 2 kilometers.


ITEM 2e - HOW THEY WORK: A VIRTUAL MODEL OF ICE STREAMS---TRT  :25
          (ANIMATION)

Experts still aren't positive how ice streams actually work.  The
current theory says that tributaries of slower ice come together
to create larger streams, often at points where elevation and
terrain act as a slight funnel.  The convergence then literally
slides on a lubricated bed of oceanic muck covered by a millimeter
thin layer of water, gaining strength as it drives toward the
ocean.

Center, Greenbelt, MD


ITEM 2g - INTERVIEW EXCERPTS------------------------------TRT 1:38

Park, MD


ITEM 2h - CONTINENTAL TOUR--------------------------------TRT 4:03

Antarctica is the coldest, windiest, driest, and on average
highest continent on Earth.  It1s huge, too-Ðthe size of the
United States and Mexico combined.  While over 97 percent of the
continent is ice covered, its surface is remarkably diverse.
Glaciers plow through 15,000 ft. mountain ranges, rising above the
land like citadel spires.  Fields of crazed ice stretch out as far
as the eye can see.  Icebergs the size of New England States calve
from walls of floating ice that are themselves as big as Texas.
By stitching together the RADARSAT data, scientists at Ohio State
University1s Byrd Polar Research Center and animators at NASA1s
Goddard Space Flight Center, Greenbelt, MD, have designed a
virtual tour of the southernmost continent.  It begins and ends at
McMurdo Station; in between are thousands of miles of mystery and
beauty.

ITEM 2i - FIMBUL ICE SHELF--------------------------------TRT 1:07

Icebergs form when hunks of ice break away from glaciers pushing
into the ocean.  Ice shelves are the edges of those glaciers,
extending out into the ocean faster than icebergs can break off
from the edge.  The Fimbul Ice Shelf has remained relatively
consistent in its appearance for the last 30 years, but
researchers are paying close attention to changes.  Ice shelves
are considered to be particularly sensitive to climatic changes
and scientists have detected a marked retreat of several along the
Antarctic Peninsula.  Note the fascinating formations along the
Fimbul, believed to be the product of glacial ice flowing over
rocky outcroppings and islands.


ITEM 2j - LATE VOSTOK-------------------------------------TRT  :30

More than two miles beneath the icy cloak shielding Antarctica
from the sky hides a massive fresh water lake.  Seen from
RADARSAT, the lake appears as a flat plain surrounded by the
sandpaper of craggy ice.  As the topographical ice sheet flows
over the subglacial lake, surface features smooth out.
Researchers are considering a drilling mission to the lake for
exploration of this remote environment.  It remains in liquid
state partially due to geothermal heating and partially because of
the insulating properties of such a thick ice blanket above.  The
drilling project faces certain technological challenges.  Lake
Vostok is also a human foothold on the continent.  It was at
Vostok Station, located at the southern end of the lake, that
Russian scientists recorded the coldest temperatures on Earth.


ITEM 2k - LARSEN ICE SHELF--------------------------------TRT  :30

In 1978, scientists predicted that global warming would lead to a
disintegration of Antarctic Peninsula ice shelves.  Spaceborne
data indicate that this prediction may be coming true.  In these
before-and-after images, note the dramatic change in the apparent
shoreline.  Scientists captured the first image in using the ERS-1
satellite in 1992.  As seen in the second image, collected by
RADARSAT in 1997, huge changes have come to the coastline.  In
1995, a 2000 sq. kilometer section of the ice shelf collapsed into
thousands of fragments that eventually drifted out to sea.
Researchers are still debating why the ice shelf broke up so
dramatically, and what significance the break-up has for
interpreting local versus global changes to the environment.
Theories include a series of warmer than usual summers which may
have caused high levels of surface melting, or an overall climate
warming trend.


ITEM 2l - LAMBERT GLACIER---------------------------------TRT 1:09

Covering more than a million square kilometers, Lambert Glacier is
one of the world1s longest and largest.  It is more than 400
kilometers long, emptying a significant portion of East Antarctica
into the Amery Ice Shelf.  Much like a major river system, Lambert
Glacier is fed by a complex series of tributaries.


ITEM 2m - EAST ANTARCTIC ICE STREAMS----------------------TRT  :42

Prior to the RADARSAT mission, scientists knew little about the
East Antarctic Ice Streams draining into the Filchner Ice Shelf.
Now for the first time they have been mapped in their entirety.
The streams are actually enormous glaciers, stretching like
conveyors of cracked ice and snow across vast stretches of the
continent.  The Recovery Glacier, one of the principal channels
comprising the East Antarctic Ice Streams, reaches over 800
kilometers into the continent1s interior.  Several of the
tributary glaciers feeding into Recovery and the large Slessor
Glacier extend for more than 250 kilometers.


ITEM 2n - THE RADARSAT SATELLITE--------------------------TRT  :16

NASA launched the Radarsat satellite for the Canadian Space Agency
in exchange for certain operational executions.  Unlike mapping
satellites that rely on reflected sunlight or infrared readings,
Radarsat1s Synthetic Aperture Radar (SAR) is able to penetrate
cloud cover or work in the dark of night.

From May 10-12, 1999, the solar wind that blows constantly from
the Sun virtually disappeared--the most drastic and longest-
lasting decrease ever observed.  Dropping to a fraction of its
normal density and to half its normal speed, the solar wind died
down enough to allow physicists to observe particles flowing
directly from the Sun's corona to Earth.  This severe change in
the solar wind also changed the shape of Earth's magnetic field
and produced an unusual auroral display at the North Pole.

http://www-spof.gsfc.nasa.gov/istp/news/9912


ITEM 3a - THE DAY THE SOLAR WIND DISAPPEARED--------------TRT  :45

As the solar wind dissipates on May 11, 1999, the magnetosphere
and bow shock around Earth expand to five times their normal size.
The aurora, which usually forms ovals around Earth's poles, fills
in over the northern polar cap.
