MEaSUREs Antarctic Boundaries for IPY 2007-2009 from Satellite Radar, Version 2
This data set, part of the NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) program, provides maps of Antarctic ice shelves, Antarctic basins, and the Antarctic coastline. The maps are assembled from 2008-2009 ice-front data from the Japan Aerospace Exploration Agency's (JAXA) ALOS PALSAR and European Space Agency's ENVISAT ASAR data, acquired during International Polar Years 2007-2009 (IPY); the InSAR-based grounding line data (MEaSUREs Antarctic Grounding Line from Differential Satellite Radar Interferometry), augmented with other grounding line sources; the Antarctic ice velocity map (MEaSUREs InSAR-Based Antarctica Ice Velocity Map); and the Bedmap-2 DEM.
See Antarctic Ice Sheet Velocity and Mapping Data for related data.
This is the most recent version of these data.
Major changes for Version 2 include:
- Added the basins IMBIE 2016 and refined
- Updated and expanded the attribute lists
Minor changes include:
- Changed grounding lines for Crosson/Dotson ice shelves based on Sentinel-1A
- Added 15 new small ice shelves
- Added missing ice rises on Larsen-C, Riiser-Larsen, Quar, Atka, Fimbul, Crosson, Borchgrevink, Beaudouin, and Pine Island ice shelves
- Fixed an issue with Wordie ice shelf boundaries (Cape Jeremy basin)
- Fixed an issue with Larsen A ice shelf, Drygalski glacier
- Fixed small gaps between polygons
- Updated names of the ice shelves (each polygon has a specific name)
- Removed grounded polygon from IceBoundaries (provided by GroundingLine_Antarctica shapefile)
