Statement

Methodology:

Radar data and details of survey location and design are presented in Vaughan et al. (2006). 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.

Surface elevation is derived from radar altimeter for ground clearance < 750 m, and the PASIN system for higher altitudes.

Note 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.
