NASA Earthdata CMR2025 · collection

This data set contains gravity measurements, including acceleration data in three orthogonal directions, from the Sander Geophysics AIRGrav airborne gravity system. Gravity data include latitude and Eotvos-corrected values, as well as free air correction at various along-flight-line time filtering scales. The data were collected as part of Operation IceBridge funded campaigns.

This dataset provides level 1B gravity data products from airborne gravity surveys for the NASA Oceans Melting Greenland (OMG) mission.

NASA Earthdata CMR2020 · collection

This award, provided by the Office of Polar Programs under the Life in Extreme Environments (LExEn) Program, supports a geophysical study of Lake Vostok, a large lake beneath the East Antarctic Ice Sheet. Subglacial ecosystems, in particular subglacial lake ecosystems are extreme oligotrophic environments. These environments, and the ecosystems which may exist within them, should provide key insig

This data set contains Greenland and Antarctica gravity measurements taken from the Sander Geophysics AIRGrav airborne gravity system.

NASA Earthdata CMR2014 · collection

This data set contains bathymetry of Arctic fjords and Antarctic ice shelves based on measurements from IceBridge Sander AIRGrav L1B Geolocated Free Air Gravity Anomalies (IGGRV1B) and IceBridge LDEO Gravimeter Suite L1B Geolocated Free Air Gravity Anomalies (IGLGS1B). The data were collected as part of Operation IceBridge funded aircraft survey campaigns.
