Ice Velocities of the Larsen B Ice Shelf and Vega Island

The above overview map is a subscene from the USGS 1 km AVHRR mosaic (Ferrigno et al., 1996).

Data Acquisition Method

All data were obtained by means of static differential GPS measurements. In each area the positions were corrected differentially to previously established reference points in Devil's Bay, Vega Island. Stake positions are referred to the top of each stake and care has been taken to correct for tilting, if any. Furthermore, in all cases the GPS measurements were pre-planned in order to ensure good satellite constellation distribution during the survey.
