Summary: | These aerogeophysical data were collected as part of the ICECAP (International Collaborative Exploration of the Cryosphere through Airborne Profiling) collaboration in 2015/16 (ICP7) and 2016/17 (ICP8). These data were in part funded by the US National Science Foundation (grant PLR-1543452 to UTIG), Antarctic Gateway, ACE-CRC the G. Unger Vetlesen Foundation, and supported by the Australian Antarctic Division through project AAS-4346. This data collection represents geolocated, time registered geophysical observations (L2 data). These data are derived from L0 and L1B data published as separate datasets. The data format are space delimited ASCII files, following the formats used for UTIG/AAD/NASA's predecessor ICECAP/OIB project at NASA's NSIDC DAAC. Fields are described in the # delimited detailed header for each granule. MAGNETICS Magnetics provides constraints on the depth to crystalline rock, and hence indicates the density of bathymetry EMGEO2 geolocated magnetic anomaly profiles, 10 Hz ASCII GRAVITY Gravity data is used to infer bathymetry, by looking at the density contrast between water and bathymetry EGCMG2 geolocated free air gravity disturbance profiles; 10 Hz ASCII ALTIMETRY Repeat track laser altimetry provides a history of thinning of outlet glaciers ELUTP2 geolocated ice surface elevation profiles; 3.5 Hz ASCII RADAR Ice penetrating radar provides the geometry of the ice shelves and outlet glaciers, and provides constraints on properties at the base of the ice (e.g. subglacial waters, sub ice shelf melting) ER2HI2 geolocated ice thickness, bed and surface elevation and echo amplitude, and surface range; 4 Hz ASCII; incoherent, unmigrated processing (pik1). |
