This dataset provides a map of the Antarctic grounding zone. The map is assembled using CryoSat-2 satellite radar altimetry data spanning between 2010-2017. This dataset provides both the limit of tidal flexure (point F) and hydrostatic equilibrium (point H) of the grounding zone. Funding was provided by the NERC grant NE/N011511/1. : See referenced publication for details. : Instrumentation: Data was collected using the CryoSat-2 spaceborne interferometric radar altimeter. See referenced publication for further details. : The data were derived at a 1 km posting. Lines are discontinuous and overall approximately 41% of the grounding zone of the larger floating ice shelves and outlet glaciers in Antarctica have been mapped.
