Focus Area: Polar Sea Ice and Sea Level Rise


Leads: Stephen Ackley and Dr. Hongjie Xie

 

Arctic and Antarctic Sea Ice

The polar pack ice regions are highly sensitive to winds, air temperature, ocean temperature, salinity, and ocean currents. Satellite remote sensing data is essential for detecting changes in sea ice concentration, extent of the ice edge, and ice thickness. While satellite remote sensing has played a crucial role in monitoring the vast and inhospitable polar regions, proper interpretation requires in-situ measurements to validate the satellite data.

Center students will be trained in using altimetry data (CryoSat-2 and ICESat-2) for studying sea ice thickness and examining sea ice volume in connection with current unprecedented changes in Arctic sea ice and potential changes in Antarctic sea ice.

Each year, one or two Center students will summer intern at the NASA Goddard Space Flight Center and/or NASA Jet Propulsion Laboratory.

Ice Sheets, Glaciers, and Sea Level

Recent analyses of data from multiple satellite missions indicate that glaciers in the Tibetan Plateau and elsewhere, and both the Greenland and Antarctic ice sheets, are losing mass and contributing to sea level rise. To develop more comprehensive and accurate models, satellite observations must be complemented and supplemented by detailed in-situ measurements.

Center students will be involved in research for performing measurements that will enable a comprehensive assessment of the shape and depth of glaciers. In addition to acquiring data, students will also be involved in research to process and analyze satellite data (CryoSat-2, ICESat-2, GRACE, GRACE-FO), and to assess glacier and ice sheet stability in various contexts such as a tropical glacier in Mexico, Tibetan glaciers, and the ice sheets of Greenland and Antarctica.

Each year, one or two Center students will summer intern at the NASA Goddard Space Flight Center and/or NASA Jet Propulsion Laboratory.
