EAGLE/ICECAP II GEOPHYSICAL OBSERVATIONS (SURFACE AND BED ELEVATION, ICE THICKNESS, GRAVITY DISTURBANCE AND MAGNETIC ANOMALIES)

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).
