Ferrigno, J.G., J.L. Mullins, J. Stapleton, P.S. Chavez, Jr., M.G. Velasco, R.S. Williams, Jr., G.F. Delinski, Jr., and D. Lear. 1995. Image Data for: Satellite Image Map of Antarctica Using Advanced Very High Resolution Radiometer (AVHRR) Images. Flagstaff, Arizona, USA: United States Geological Survey (USGS). Available at http://terraweb.wr.usgs.gov/TRS/projects/Antarctica/AVHRR.html. Accessed on 09 May 2008. Background: The satellite images used in the mosaic were acquired by the Advanced Very High Resolution Radiometer (AVHRR) sensors on the National Oceanic and Atmospheric Administration (NOAA) satellites; the images used in the mosaic were collected during the period 1980 to 1994. Although the AVHRR scans a 2400 km-wide swath and can image nearly half of the continent of Antarctica on a single orbit, 63 sections of 38 scenes were needed to compile the nearly cloud-free digital mosaic. Band 1 of AVHRR covers the wavelengths of 580 to 680 nm. This mosaic is viewable here using a nominal contrast stretch.

Server 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 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.
