2001 November. Birth of a Large Iceberg in Pine Island Bay, Antarctica [223kb
PDF NASA Lithograph] This lithograph shows the break-off of a large
tabular iceberg from the Pine Island Glacier in West Antarctica. This
event occurred between November 4th and 12th, 2001, and provides
powerful evidence of rapid changes underway in this area of Antarctica.
The three images were acquired by the vertical-viewing (nadir) camera of
the Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard
NASA's Terra spacecraft. The dimensions of the iceberg are approximately
42 kilometers by 17 kilometers (26 miles by 11 miles).

May 2000. Low
Water in Lake Mead [328KB PDF NASA Lithograph] About
96% of the water in Lake Mead is from melted
snow that falls in Colorado, Utah, New Mexico,
and Wyoming. The past two years have brought
severe drought to the western states, and Colorado
River runoff has been far below normal during
this period. The effect is a drop in lake levels
that is visible from NASA satellites. One of
NASA's Earth Science Enterprise research focus
areas is the global water and energy cycle governing
the precipitation, evaporation, storage and
runoff of water. The Earth Science Enterprise
Applications Program facilitates the practical
use of this knowledge by national and regional
decision makers for better management of fresh
water resources.
