Summary

Abstract: This data set provides a 1 km resolution Digital Elevation Model (DEM) of Antarctica. The DEM combines measurements from the European Remote Sensing Satellite-1 (ERS-1) Satellite Radar Altimeter (SRA) and the Ice, Cloud, and land Elevation Satellite (ICESat) Geosciences Laser Altimeter System (GLAS). The ERS-1 data are from two long repeat cycles of 168 days initiated in March 1994, and the GLAS data are from 20 February 2003 through 21 March 2008. The data set is approximately 240 MB comprised of two gridded binary files and two Environment for Visualizing Images (ENVI) header files viewable using ENVI or other similar software packages. The data are available via FTP.

Quality Equipment modifications

Several modifications were made to the extrusion gravity corer during the sampling season. Before commencing the sampling, the corer was stripped down and cleaned as several components, including the spring and cocking device were corroding, and therefore not functioning efficiently. Seals were also replaced and lubricated. Some tools and spare parts should be ...
