2002, Open-File Report 2002-391
Glacier Bay is a diverse fjord ecosystem with multiple tidewater glaciers and complex biological, geological, and oceanographic patterns that vary greatly along its length. The bay was completely glaciated prior to the 1700's, and subsequently experienced the fastest glacial retreat recorded in historical times. As a result, some of the...
A new method for GPS-based wind speed determinations during airborne volcanic plume measurements
Michael P. Doukas
2002, Open-File Report 2002-395
Begun nearly thirty years ago, the measurement of gases in volcanic plumes is today an accepted technique in volcano research.

H. A. Al-Rabai’ah, H. L. Koh, Donald L. DeAngelis, Hooi-Ling Lee
2002, Water Science and Technology (46) 71-78
Temperature variation is an important factor in Everglade wetlands ecology. A temperature fluctuation from 17°C to 32°C recorded in the Everglades may have significant impact on fish dynamics. The short life cycles of some of Everglade fishes has rendered this temperature variation to have even more impacts on the...
