Summary
Abstract: Grounding Zone of the Amery Ice Shelf, East Antarctica defined by break of surface slope as determined through interpretation of MODIS images. It defines the landward edge of the grounding zone and therefore the maximum extent of the ice shelf.

The MODIS data from the 250 m Channel 2 were processed to a reflectance product and remapped to a Polar Stereographic Projection. The image contrast was ... View entire text

Quality The position of the grounding zone was determined by visual inspection and manual digitisation of features in MODIS images that are interpreted as being the break of surface slope. Quality is lower for the south-west sector where the interpretation is less certain. The locations will delineate the probable maximum extent of the Amery Ice Shelf. In any case the line is expected to define the landward edge of the grounding zone.
