This dataset consists of airborne geophysical data collected between 1994 and 2000 by the National Science Foundation's Support Office for Aerogeophysical Research (SOAR) at the University of Texas Institute for Geophysics. Meaurements were made using a laser altimeter, a radar echo sounder, a gravimeter, and a magnetometer. Positioning was accomplished with kinematic, differential carrier-phase GPS. Multiple areas within Antarctica were covered, including both grid and line surveys. Some areas have reduced data products (i.e., surface and bed elevations, ice thickness, gravity and magnetic field anomalies).
