Images taken by NASA's Sea-viewing Wide Field-of-view Sensor
(SeaWiFS) satellite on October 15 and December 7 showing the West
African Cape Verde Islands' effect on wind fields.   The first
image shows the dust blowing from the Sahara Desert on the upper
right side moving west but getting trapped by the altitude of the
islands.  The volcanic islands are high enough to interrupt the
wind field as seen by the clear water just south of each of the
islands.  When wind blows past structures such as these, a vortex
is usually created in the wake of the water, as seen in the
rippled ocean currents.

ITEM 3a - HYDRA A: A CLUSTER OF GALAXIES------------------TRT  :15
          IN THE CONSTELLATION HYDRA

This image shows a radio (green and maroon) overlay of the Chandra
X-ray (pink, and blue) image of Hydra A.  Large magnetized bubbles
of radio-emitting high energy particles expanding from the center
of the cluster have pushed through the 40 million degree X-ray
emitting gas.  As the largest gravitationally bound objects in the
universe, galaxy clusters provide crucial clues for understanding
the origin and fate of the universe.  Hydra A is 840 million light
years from Earth.


ITEM 3b - X-RAY IMAGE OF HYDRA A GALAXY CLUSTER-----------TRT  :15

NASA's Chandra X-ray Observatory image of the Hydra A galaxy
cluster has revealed a possible solution to a Herculean puzzle
about the fate of the largest objects in the universe.  For years
astronomers have been searching unsuccessfully for large
quantities of matter they believed must be flowing into the
central regions of galaxy clusters.  The Chandra image of Hydra A
displays for the first time long snake-like strands of 35 million
degree gas extending away from the center of the cluster.  These
structures show that the inflow of cooling gas is deflected by
magnetic fields produced by explosions from a central black hole.
As the largest gravitationally bound objects in the universe,
galaxy clusters provide crucial clues for understanding the origin
and fate of the universe.

Synopsis:  The 1997-98 El Niño/La Niña had an unprecedented
roller-coaster effect on the oceanic food chain across a vast
swath of the Pacific, plunging chlorophyll levels to the lowest
ever recorded in December 1997 and spawning the largest bloom of
microscopic algae ever seen in the region the following summer.
According to new results published in the December 10 issue of the
journal Science, El Niño also dramatically reduced the amount of
carbon dioxide normally released into the atmosphere by the
equatorial Pacific Ocean.

ITEM 4a - AN IMMENSE PACIFIC BLOOM

This sequence illustrates the vast size and intensity of the
ocean's biological rebound from El Niño.  Satellite imagery from
NASA's Sea-viewing Wide-Field-of-view Sensor (SeaWiFS) instrument
showed nearly a complete lack of plankton along the equatorial
Pacific during El Niño.  The cool waters associated with La Niña
brought nutrients from the below the surface and enabled an
enormous plankton bloom (shown in green).


ITEM 4b - REBOUND FROM EL NIÑO

The SeaWiFS data revealed surprisingly low levels of plankton
coinciding with El Niño's strongest phase.  The cooler waters
associated with La Nina brought a huge plankton bloom along the
equator (shown in green).


ITEM 4c - EXPLOSION IN THE GALAPAGOS

SeaWiFS documented the rapid demise of El Niño in the waters
around the Galapagos Islands.   The images show an explosion in
plankton growth as the warm El Niño waters blamed for choking off
essential ocean nutrients are replaced by deep cold upwelled
waters.  The false color images, which document plankton
concentrations from May 9-24 1998, show that life in the region to
the west archipelago has returned in remarkable abundance.   High
concentrations are shown in red.  Areas occluded by clouds are
shown in white.


ITEM 4d - THE CARBON CONNECTION - PHYSICAL PROCESSES

By understanding the magnitude of the huge plankton bloom,
scientists were able to calculate how changes in biologic activity
caused massive changes in carbon dioxide.  Scientists determined
that El Niño cut the amount of carbon dioxide released into the
atmosphere by 700 million metric tons.  The deep ocean waters
normally release large amounts of carbon dioxide.  During El Niño,
the carbon dioxide-rich waters were held below the surface.


ITEM 4e - THE CARBON CONNECTION - BIOLOGICAL PROCESSES

Nutrients in the cooler waters associated with La Niña were
brought to the surface and helped fuel a huge plankton bloom.
This animation shows how the tiny plants can lock up carbon when
they die.


ITEM 4f - THE 1997-98 EL NIÑO

The 1997-98 El Niño was truly a global event.  The sequence shows
a superimposition of sea surface temperature anomalies on
anomalies of the sea surface elevation.  Warmer than normal
temperatures are shown in red and cooler than normal temperatures
are shown in blue.


ITEM 4g - 3-D EL NIÑO

The space-based perspective provided by satellite observations
trace the evolution of El Niño (shown in red) from its beginning
in early 1997 through its decline in early 1998.  The onset of La
Niña can be seen as the emergence cooler than normal temperatures
(shown in blue) along the equator.


ITEM 4h - PHYTOPLANKTON -- UP CLOSE AND PERSONAL

Images of phytoplankton and zooplankton.  Plankton are lowest
rungs in the oceanic food chain.


ITEM 4i - BUOY ARRAY

Scientists also used data from the National Oceanic and
Atmospheric Administration's Tropical Atmosphere Ocean array.


ITEM 4j - EYE IN THE SKY - SEAWIFS

NASA's Sea-viewing Wide Field-of-View Sensor (SeaWiFS) gave
researchers an unprecedented view into the extreme biological
effects of this El Niño/La Niña event.


ITEM 4k - HOW SEAWIFS "SEES" PLANKTON

The SeaWiFS instrument detects subtle differences in ocean color
and is used to determine the concentrations of chlorophyll found
in plankton.


ITEM 4l - SCIENTISTS B-ROLL

Scientists at NASA's Goddard Space Flight Center study El Niño and
La Niña.

ITEM 5a - EXAMINING ARCTIC OZONE--------------------------TRT 1:38

NASA scientists are joining researchers from Europe, Russia,
Canada and Japan to mount the largest field-measurement campaign
ever to assess ozone amounts and changes in the Arctic upper
atmosphere this winter.  This collaborative campaign will measure
ozone and other atmospheric gases using satellites, airplanes,
heavy-lift and small balloons, and ground-based instruments.  From
November 1999 through March 2000, researchers will examine the
processes that control ozone amounts during the Arctic winter at
mid to high latitudes.
