OIB

Mission: Bellingshausen-Amundsen Divide IS-2
Priority: Medium

This new mission is designed to sample the area of the Bryan Coast and inland, include PIG drainage to the Amundsen Sea and Evans drainage to the Weddell, all along ICESat-2 ground tracks. It also overflies two ice cores sites known as Bryan and Ferrigno.

Mission: Thwaites 2002
Priority: Baseline

This mission is an amalgamation of previous OIB Thwaites flights, and is primarily intended to retain the portions of those flights which in turn repeated the 2002 NASA/Chilean lines. This mission yields a very long dh/dt time history of measurements along these lines.

Mission: Long Line East IS-2
Priority: High

An international team of researchers, including a NASA glaciologist, has discovered a large meteorite impact crater hiding beneath more than a half-mile of ice in northwest Greenland. The crater — the first of any size found under the Greenland ice sheet — is one of the 25 largest impact craters on Earth, measuring roughly 1,000 feet deep and more than 19 miles in diameter, an area slightly larger than that inside Washington’s Capital Beltway.

Mission: Hamilton Line - TAM Sector
Priority: Baseline

Mission: Thwaites-Getz 3 Beam IS-2
Priority: Medium

Mission: Foundation Lakes IS-2
Priority: Low
This flight is a dh/dt repeat of the identical 15 October 2012 flight. It occupies straightened approximations of the Foundation and Support Force ice streams, and crosses several subglacial lakes in their upper portions. Many of the original lines were redesigned for 2018 along ICESat-2 ground tracks. For these tracks, we specifically target the strong beam of the center beam pair.

Mission: Support Force / Upper Blackwall IS-2
Priority: Low

This new flight is designed to survey the channel of Support Force and upper Blackwall Glacier, mostly along ICESat-2 ground tracks. For these tracks, we specifically target the strong beam of each beam pair. The cross-flow lines also address gaps in Bedmap-2 coverage.
