Operation IceBridge makes airborne altimetry, radar, and other geophysical measurements to monitor and characterize the cryosphere. IceBridge data will improve knowledge of the contribution of the major Arctic and Antarctic ice sheets and sea ice to sea-level rise. Major goals include: (1) Make airborne altimetry measurements of ice sheets and sea ice to extend and improve the observations begun by the Ice, Cloud, and land Elevation Satellite (ICESat); (2) Link measurements made by historical airborne laser altimeters, ICESat, ICESat-2 and CryoSat-2, to allow accurate comparison and production of a long-term ice-altimetry record; (3) Monitor key, rapidly changing areas of Arctic and Antarctic ice to maintain a long-term observation record; and (4) Provide data to improve understanding of ice dynamics and better constrain predictive models of sea-level rise and sea-ice cover conditions.
Field Season Overview:
Up to 45 team members will deploy to McMurdo Station in the austral summer season. They will conduct aerial surveys using their own P-3 NASA aircraft, equipped with several geophysical instuments, including laser altimeters, radar systems, digital cameras, a gravimeter, a magnetometer, and several GPS units. IceBridge will operate from the Sea Ice runway and is planning to fly every day, weather permitting. The general flight length is between 8-10 hours.
