Abstract:
The National Snow and Ice Data Center (NSIDC) Antarctic Cryosphere Access Portal (A-CAP) is a map server that provides data and information pertinent to the frozen regions of the Antarctic ice sheet and the Southern Ocean, including monthly climatologies of sea ice extent and concentration, ice sheet elevation and accumulation, satellite imagery, and more. In addition to providing map images and source data through Open Geospatial Consortium, Inc. (OGC) protocols--Web Map Service (WMS), Web F...

The National Snow and Ice Data Center (NSIDC) Antarctic Cryosphere Access Portal (A-CAP) is a map server that provides data and information pertinent to the frozen regions of the Antarctic ice sheet and the Southern Ocean, including monthly climatologies of sea ice extent and concentration, ice sheet elevation and accumulation, satellite imagery, and more. In addition to providing map images and source data through Open Geospatial Consortium, Inc. (OGC) protocols--Web Map Service (WMS), Web Feature Service (WFS), and Web Coverage Service (WCS)--a dynamic Web interface for exploring these data is also available at http://nsidc.org/agdc/acap/. If you have questions, comments or suggestions, please contact NSIDC User Services at +1.303.492.6199 or nsidc@nsidc.org.

Stockli, R, Vermote, E., Saleous, N., Simmon R., and D. Herring. 2005. The Blue Marble Next Generation - A true color earth dataset including seasonal dynamics from MODIS. Greenbelt, Maryland USA: NASA Earth Observatory. Digital media. Available at ftp://sidads.colorado.edu/pub/DATASETS/BM/ and http://visibleearth.nasa.gov/view_set.php?categoryID=2355. Accessed 12 September 2007. Background: Cloud-free satellite image mosaic at 500-meter resolution compiled from NASA's Moderate-Resolution Imaging Spectroradiometer (MODIS) spaceborne remote sensing instrument for the month of January in 2004. Included in this data set is topographic and bathymetric relief shading from the Shuttle Radar Topography Mission (SRTM), GTOPO30, Radarsat Antarctic Mapping Project (RAMP) Digital Elevation Model (DEM) Version 2, and the General Bathymetric Chart of the Oceans (GEBCO).

Available at http://nsidc.org/data/smmr_ssmi_ancillary/monthly_means.html. Accessed 27 June 2008. Compiled from: Cavalieri, D., C. Parkinson, P. Gloersen, and H. J. Zwally. 1996. Sea ice concentrations from Nimbus-7 SMMR and DMSP SSM/I passive microwave data. Boulder, Colorado USA: National Snow and Ice Data Center. Digital media. Available at http://nsidc.org/data/nsidc-0051.html. Background: Sea ice extent includes all areas where sea ice concentration is greater than or equal to 15%. Monthly climatologies of sea ice concentration represent mean ice concentration percentages for each month over the entire time period 1979-2007, which is generated from passive microwave brightness temperature data derived from Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) and Defense Meteorological Satellite Program (DMSP) -F8, -F11 and -F13 Special Sensor Microwave/Imager (SSM/I) radiances at a grid cell size of 25 x 25 km using the NASA Team algorithm developed by the Oceans and Ice Branch, Laboratory for Hydrospheric Processes at NASA Goddard Space Flight Center (GSFC).
