Data were acquired using the BAS PASIN depth sounding radar mounted in the BAS aerogeophysically equipped Twin Otter "Bravo Lima". Data are provided as XYZ ASCII line data. Data were collected as part of the UK Natural Environment Research Council AFI grant NE/G013071/1.

(2012). Radar data were collected using the PASIN radar echo sounding system (table 1 (Corr et al., 2007)). Data provided here includes picks of surface and ice sheet bed elevation. Note a single flight may contain data from two or more SEGY files, identified in the SEGYname channel. Surface elevation is derived from radar altimeter for ground clearance < 750 m, and the PASIN system for higher altitudes. Full channel name definition is given in the description below. Note the ice thickness over regions of thinner ice was independently picked a second time with different processing parameters. This additional ice thickness data is also available. In the database split by line the sections are defined as follows L= main survey grid lines, T=main survey grid lines, P=long transits, D=turns.
