Layer Abstract

Haran, T., J. Bohlander, T. Scambos, T. Painter, and M. Fahnestock compilers. 2005, updated 2006. MODIS mosaic of Antarctica (MOA) image map. Boulder, CO, USA: National Snow and Ice Data Center. Digital media. Available at http://nsidc.org/data/nsidc-0280.html. Background: The MODIS Mosaic of Antarctica (MOA) surface morphology image map is derived from composites of 260 MODIS (Moderate-resolution Imaging Spectroradiometer) orbit swaths acquired between 20 November 2003 and 29 February 2004. The MOA provides a cloud-free view of the ice sheet, ice shelves, and land surfaces. All land areas larger than a few hundred meters that are south of 60 deg S are included in the mosaic, as ell as persistent fast ice regions and some grounded icebergs present near the coast in the 2003-2004 austral summer. The MOA surface morphology image map is derived from digitally processed MODIS Band 1 data: this is viewable here at a grid scale of 125 m and using a very low contrast stretch with minimum and maximum surface brightness values of 9000 and 23000 respectively.

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.
