Ice drilling allows scientists studying glaciers and ice sheets to gain access to what is beneath the ice, to take measurements along the interior of the ice, and to retrieve samples. Instruments can be placed in the drilled holes to record temperature, pressure, speed, direction of movement, and for other scientific research, such as neutrino ...
Agassiz's demonstration of the great difficulty of drilling deep holes in glacier ice discouraged other researchers from further efforts in this direction. [12] It was decades before further advances were made in the field, [12] but two patents, the first ice-drilling related ones to be issued, were registered in the United States in the late 19th century: in 1873, W.A. Clark received a patent ...
This is a list of ice cores drilled for scientific purposes. Note that many of these locations are on moving ice sheets, and the latitude and longitude given is as of the date of drilling.

Ice core sample taken from drill. An ice core is a core sample that is typically removed from an ice sheet or a high mountain glacier.Since the ice forms from the incremental buildup of annual layers of snow, lower layers are older than upper ones, and an ice core contains ice formed over a range of years.
The European Project for Ice Coring in Antarctica (EPICA) is a multinational European project for deep ice core drilling in Antarctica. Its main objective is to obtain full documentation of the climatic and atmospheric record archived in Antarctic ice by drilling and analyzing two ice cores and comparing these with their Greenland counterparts ...
Drilling was performed using a conventional core wireline system with a drill derrick, protected by a cover against the rough climate. Sea ice was 2 m (6.6 ft) thick with a water depth of 150–300 m (490–980 ft) below.
NEEM Camp was a small research facility on the northern Greenland Ice Sheet, used as a base for ice core drilling. It was located about 313 km east of the closest coast, Peabody Bay in northern Greenland, 275 km northwest of the historical ice sheet camp North Ice, and 484 km east-northeast of Siorapaluk, the closest settlement. There was one ...
Drilling began in 1999 and was completed at bedrock in 2003. [1] The cores are cylinders of ice 11 centimeters in diameter that were brought to the surface in 3.5-meter lengths. The NGRIP site was chosen to extract a long and undisturbed record stretching into the last glacial , and it succeeded.
