NSIDC has released the following data sets for access through the AGDC Antarctic Cryosphere Access Portal (A-CAP).
- Luyendyk, B. and Wilson, D. 2003. Surface Elevation and Ice Thickness, Western Marie Byrd Land, Antarctica Boulder, CO: National Snow and Ice Data Center. Digital media. (NSIDC-0119). Available maps include elevation and ice thickness. (Figure 1)
- Young, D. A., S. D. Kempf, D. D. Blankenship, J. W. Holt, and D. L. Morse (in press), New airborne laser altimetry over the Thwaites Glacier Catchment, West Antarctica, Geochemistry, Geophysics, Geosystems, doi:10.1029/2007GC001935. (NSIDC-0334). The data set provides elevation data for the Thwaites Glacier Catchment in Western Antarctica. (Figure 2)
- Also, additional cores have been added to the Antarctic ice core overlay. Available ice core locations include Byrd, Dome B, Dome Fuji, EPICA, Komsomolskaya, Siple Dome, Taylor Dome, Vostok, and WAIS divide.To access this overlay, click to expand the overlays menu, select Antarctic ice cores, and click update to display ice core locations. To access information about an ice core, select query from the click-on-map menu (left side of screen), and click on an ice core location on the map. (Figure 3)
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. For more information on how to access data using A-CAP, see the A-CAP User Manual.
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.
