The Greenland Ice Core Project ... Jouzel, J. (2008). High-Resolution Greenland Ice Core Data Show Abrupt Climate Change Happens in Few Years. Science (American ...
The drilling site of the North Greenland Ice Core Project (NGRIP or NorthGRIP) is near the center of Greenland (75.1 N, 42.32 W, 2917 m, ice thickness 3085). Drilling began in 1999 and was completed at bedrock in 2003. [ 1 ]
The ice cores provide a proxy archive of temperature and atmospheric constituents that help to understand past climate variations. The preliminary GISP field work started in 1971 at Dye 3 ( 65°N 43°W / 65°N 43°W / 65; -43 ( Dye 3 ) ), where a 372 meter deep, 10.2 cm diameter core was recovered
New research suggests the Greenland ice sheet is on track to cross a critical threshold that could cause runaway melting, but that it’s also possible the threshold will be crossed temporarily, ...
The Greenland Ice Sheet lost 5,091 sq km (1930 sq miles) of area between 1985 and 2022, according to a study in the journal Nature published on Wednesday, the first full ice-sheet wide estimate of ...
Retrieve ice cores that reach back over 1.2 million years, in order to obtain multiple iterations of ice core record for the 40,000-year long climate cycles known to have operated at that time. Current cores reach back over 800,000 years, and show 100,000-year cycles. Improve ice core chronologies, including connecting chronologies of multiple ...
The Greenland and Antarctic ice sheets are now losing more than three times as much ice a year as they were 30 years ago, according to a new comprehensive international study. Using 50 different ...
The Dye 3 cores were part of the GISP and, at 2037 meters, the final Dye 3 1979 core was the deepest of the 20 ice cores recovered from the Greenland ice sheet. [5] The surface ice velocity is 12.5 ma −1, 61.2° true. [11] At 500 m above bedrock, the ice velocity is ~10 ma −1, 61.2° true. [11]
