Program element A.49 supports participation in the IceBridge Science Team (IST) during the third and final phase of IceBridge data collection during Fiscal Year (FY) 2017—2019 to provide advice to the IceBridge project office on flight planning. For this final phase of IceBridge, the mission focuses on ensuring that its observations are set to build a bridge of altimetry measurements from the ICESat to ICESat-2 satellites to develop a multidecadal time series.
The specific measurement and science goals for IceBridge are summarized as follows:
- Make airborne altimetry measurements over the ice sheets and sea ice to extend the record of observations begun by ICESat.
- Link the measurements made by ICESat and ICESat-2, and where possible CryoSat-2 (http://www.esa.int/Our_Activities/Observing_the_Earth/The_Living_Planet_Programme/Earth_Explorers/CryoSat-2), to allow accurate comparison and production of a long-term, ice altimetry record.
- Use airborne altimetry to monitor key, rapidly changing areas of ice in the Arctic and Antarctic to maintain a long term observation record, improve understanding of glacial dynamics, and improve predictive models of sea level rise and sea ice cover.
- In conjunction with altimetry measurements, collect other remotely sensed data to improve predictive models of sea level rise and changes in sea ice cover, especially the following:
- Snow thickness, especially over Arctic sea ice;
- Ice thickness and structure;
- Bed topography underlying land-based ice;
- Bathymetry beneath floating ice shelves;
- Snow accumulation and firn structure; and
- Other geophysical constraints that will improve estimates of the geothermal and oceanic heat flux.
Notices of Intent are requested by August 1, 2016, and proposals are due by September 19, 2016.
