The data set, Subglacial topography: airborne geophysical survey of the Amundsen Sea Embayment, Antarctica (NSIDC-0292), is now available through the Antarctic Cryosphere Access Portal (A-CAP). The data set provides maps of bedrock elevation and ice thickness for the Amundsen Sea Embayment. The maps are composed of closely spaced (5 km) point measurements. Users can zoom in to view individual points, and click on a point to obtain the data value and geographic location of that point.
For documentation and source data, click on the information icon () next to the data set, or choose query from the map menu and click on a point on the map. To view legend information, click view map legend in the map information menu, located on the bottom left corner of the screen. The legend appears as a pop-up window.
A-CAP is a geo-visualization and data download tool developed at the National Snow and Ice Data Center (NSIDC) Antarctic Glaciological Data Center (AGDC). A-CAP provides AGDC data and other Antarctic-wide parameters, including glaciology, ice core data, snow accumulation, satellite imagery, Digital Elevation Models (DEM's), sea ice concentration, and many other cryosphere-related scientific measurements.
We welcome your feedback on this project, which is currently in active development. If you have questions, comments or suggestions, please contact the A-CAP Team. A-CAP is developed using MapServer, an open source development environment for building spatially-enabled Internet applications.
