NASA Finds Possible Second Impact Crater Under Greenland Ice

A NASA glaciologist has discovered a possible second impact crater buried under more than a mile of ice in northwest Greenland. This follows the finding, announced in November 2018, of a 19-mile-wide crater beneath Hiawatha Glacier – the first meteorite impact crater ever discovered under Earth’s ice sheets.

Huge Cavity in Antarctic Glacier Signals Rapid Decay

A gigantic cavity — two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall — growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier. The findings highlight the need for detailed observations of Antarctic glaciers' undersides in calculating how fast global sea levels will rise in response to climate change.

OIB - DC-8 - AFRC 11/16/18 Science Report

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.
 

OIB - DC-8 - AFRC 11/15/18 Science Report

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.

International Team, NASA Make Unexpected Discovery Under Greenland Ice

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.

OIB - DC-8 - AFRC 11/12/18 Science Report

Mission: Hamilton Line - TAM Sector
Priority: Baseline
 

OIB - DC-8 - AFRC 11/11/18 Science Report

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

OIB - DC-8 - AFRC 11/10/18 Science Report

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.
