Tropical Cyclone Percy (20P) east of Pago Pago, Pacific Ocean

Cyclone Percy continued its rampage across the South Pacific on March 1, 2005, after battering the Northern Cook Islands with its powerful 140-knot wind gusts. This Moderate Resolution Imaging Spectroradiometer ( MODIS ) image taken by NASAs Aqua satellite at 2:40 local time on February 28 (00:40 UTC on March 1), shows that the storm now has a clearly defined eye. When the image was taken, Percy had just passed over Pukapuku and Nassau, leaving both in shambles. According to news reports, no structures escaped damage on Nassau and just 10 buildings remain intact in Pukapuku. The storm had sustained winds of 213 kilometers per hour (132 mph) with gusts to 260 kph (160 mph), making it a Category 4 storm on the Saffir-Simpson scale. The storm is weakening as it moves south towards the southern Cook Islands and Rarotonga. Percy is the fourth cyclone to strike the Cook Islands in the past four weeks.

Malaspina Glacier, Alaska

This false-color image shows an area of 55 x 40 km over the southwest part of the Malaspina Glacier and Icy Bay in Alaska. The scene was acquired on June 8, 2001, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), flying aboard NASAs Terra satellite. The composite of infrared and visible bands results in the snow and ice appearing light blue. Dense vegatation is yellow-orange and green, and less vegetated, gravelly areas are orange. According to Dr. Dennis Trabant (US Geological Survey, Fairbanks), the Malaspina Glacier is thinning. Its terminal moraine protects it from contact with the open ocean; without the moraine, or if sea level rises sufficiently to reconnect the glacier with the ocean, the glacier would start calving and retreat significantly. ASTER data are being used to help monitor the size and movement of some 15,000 tidal and piedmont glaciers in Alaska. Evidence derived from ASTER and many other satellite and ground-based measurements suggests that only a few dozen Alaskan glaciers are advancing. The overwhelming majority of them are retreating.
