Ice thickness and sea level change

Nasa Conferences and Workshops

ANTARCTIC SEA ICE THICKNESS FROM PASSIVE MICROWAVE RETRIEVALS OF SNOW DEPTH
TIME: Tues., Dec. 11, 5:40 p.m. EST (2:40 p.m. PST), MW 3006
SESSION: C23B-05
Antarctic sea ice thickness estimates from satellite altimeters are dependent on accurate estimates of snow depth. Satellite data provide a good indicator of snow depth over broad scales in most cases and for all areas except for the East Antarctic sector. NASA’s Thorsten Markus of Goddard Space Flight Center, Greenbelt, Md., will discuss how satellite snow depth can provide reasonable estimates of regionally-averaged ice thicknesses.

SATELLITE AND IN SITU OBSERVATIONS OF REGIONAL SEA LEVEL CHANGE: WHAT CAN THEY TELL US ABOUT FUTURE CHANGES?
TIME: Thurs., Dec. 13, 7 p.m. EST (4 p.m. PST), MW 3003
SESSION: G44A-01
Satellite altimetry has provided precise sea level measurements since the early 1990s. Melting of mountain glaciers and the polar ice sheets are expected to create distinct patterns of regional sea level change. While these have yet to be detected in satellite altimeter data, satellite gravity missions such as NASA's Gravity Recovery and Climate Experiment (GRACE) provide a means of monitoring ice melt contributions directly. With these and other tools we can begin to put together a framework for predicting what regional sea level change will look like in the future.
