Synopsis |
| PORTRAIT OF OUR PLANET | G97-042 | 12/2/97 | 00:00:00 | First continuous global look at Earth's biosphere taken by NASA's Sea-viewing Wide Field-of-view Sensor (SeaWiFS). Portrait allows scientists to monitor global plant life for the first time. SeaWiFS gives scientists a new tool to measure the effects of El Nino and global warming, and also do environmental monitoring, such as, tracking oil spills and cholera outbreaks. The global ocean color images from SeaWiFS will be used by researchers to study how human-induced and natural events affect the global biosphere.
The Sea-viewing Wide Field-of-view Sensor (SeaWiFS) was launched at noon PDT, Aug. 1, 1997 from Vandenberg Air Force Base, Calif. into a low-Earth orbit.

TAPE CONTENTS: |
| ITEM (1): COMPLETE GLOBAL BIOSPHERE :
|
| ITEM (2): OCEAN AREAS & VEGETATION - Ocean areas in the figure that have relatively high concentrations of chlorophyll-and, therefore, high numbers of microscopic green plants called phytoplankton are colored green, yellow and red. On land, areas with little or no vegetation are colored brown and heavily vegetated are dark green. [Image begins with ocean color, then adds the terrestrial vegetation , then zooms to North America.]
|
| ITEM (3): ANOTHER VIEW - Image of globe only with no zoom.
|
| ITEM (4): DETAILED VIEW - Beginning with ocean color then dissolving to show terrestrial biosphere, these images show: North America, Western Canada, Alaska, Europe, Australia, Japan, South America and Africa.
