Ice surface, ice base and lake bed elevation data from seismic data acquired over Subglacial Lake Ellsworth 2007-08
Point data measurements of ice surface, ice base and lake bed elevation are given from Subglacial Lake Ellsworth (SLE), West Antarctica. The data were acquired during the austral summer of 2007-2008. Five seismic reflection lines were acquired over SLE, with surface elevation determined by dual frequency GPS.
Funding was provided by NERC AFI, award numbers NE/D009200/1, NE/D008638/1 and NE/D008751/1. Logistics support: British Antarctic Survey. Equipment support: NERC Geophysical Equipment Facility (loan numbers 838 and 870).

- Statement
- Data quality are good; the ice-water interface can be clearly picked on virtually all traces, the water-bed interface can be picked in most places, except close to the lake shoreline and at a few other locations on each line. Only the results from traces where both reflections can be picked are provided. Nominal point spacing is 5 m, with occasional gaps at the locations where both reflections could not be picked. Absolute errors in ice- and water-column thickness are 10 m and 1.5 m respectively, although relative thicknesses changes (trace-to-trace) are more precise. See publications for full details.
