UK Polar Data Centre, Natural Environment Research Council, UK Research & Innovation. https://doi.org/10.5285/3adb739a-9eda-434d-9883-03ab092cabae During the austral summer of 2004/05 a collaborative US/UK field campaign undertook a systematic geophysical survey of the entire Amundsen Sea embayment using comparable airborne survey systems mounted in Twin Otter aircraft. Here we present the portion of the survey covering the Pine Island Glacier basin led by British Antarctic Survey. Operating from a temporary field camp (PNE, S 77deg34' W 095deg56'); we collected ~35,000 km of airborne survey data. Our aircraft was equipped with dual-frequency carrier-phase GPS for navigation, radar altimeter for surface mapping, wing-tip magnetometers, gravity meter, and a new ice-sounding radar system (PASIN). We present here the bed elevation picks from airborne radar depth sounding collected using the BAS PASIN radar depth sounding system. Data are provided as XYZ ASCII line data.

(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.
