Proposal Due Dates delayed for ROSES-12 Appendix A.49 Studies with ICESat and CryoSat-2

NASA solicits investigations to derive geophysical information from NASA's Ice, Cloud, and land Elevation Satellite (ICESat) and the European Space Agency's CryoSat-2. These altimetry missions were optimized to characterize changes in the continental ice sheets of Antarctica and Greenland and the sea ice of the Arctic and Southern Oceans. The missions' primary goals are to understand the contributions of polar ice to current and future sea level rise and the coupling of changes in polar sea ice cover to the Earth system. Investigations are encouraged that:

* create long term, integrated records of change in the polar ice sheets;

* characterize processes of change in polar ice, especially couplings to climate forcings and insight into physical processes that improves predictive models; and

* any other innovative investigations using ICESat and CryoSat-2 observations for Earth science research.

Proposals for Appendix A.49 Studies with ICESat and CryoSat-2 are now due February 22, 2013. Table 2 and 3 of the Summary of Solicitation for this NRA will be updated to reflect these changes.

On or about February 13, 2012, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2012" (NNH12ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on the RSS feed at:

Questions concerning Appendix A.49 Studies with ICESat and CryoSat-2 may be addressed to Thomas Wagner, Earth Science Division, Science Mission Directorate, NASA Headquarters, Washington, DC 20546-0001. Email:; Telephone: 202-358-4682.
