Session 4. Ice sheets and ice shelves – mass balance
Chairs: Mal McMillan, Aleah Sommers
- Long-term altimeter records, with uncertainties, are important for constraining model projections of future sea level rise.
- Multiple missions/ multiple sensors help constrain ice sheet mass balance, due to both surface processes and ice dynamics.
- CryoSat-2 and ICESat-2 observations are complementary, useful for filling in gaps and validation.
- Applications on ice-sheet-wide scale (Antarctica and Greenland) and long-term scale, also for smaller regions and specific events (e.g. dynamic collapse of ice shelf in East Antarctica)
- Regional assessments are important for understanding differences between different geodetic techniques.
- For robust observation and continued monitoring to understand overall mass balance of ice sheets and relevant processes, essential to maintain a continuous long-term record of measurements with high spatial and temporal resolution
