The ACFEL ice auger showing an ice core pushed up into the core remover barrel. [1]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.
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 ...
The Cold Regions Research and Engineering Laboratory (CRREL) is a United States Army Corps of Engineers, Engineer Research and Development Center research facility headquartered in Hanover, New Hampshire, that provides scientific and engineering support to the U.S. government and its military with a core emphasis on cold environments.
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 ...
What is probably the world's oldest ice, dating back 1.2m years ago, has been dug out from deep within Antarctica. Working at temperatures of -35C, a team of scientists extracted a 2.8km-long ...
A pressure ridge, when consisting of ice in an oceanic or coastal environment, is a linear pile-up of sea ice fragments formed in pack ice by accumulation in the convergence between floes. Such a pressure ridge develops in an ice cover as a result of a stress regime established within the plane of the ice.
Sea ice was 2 m (6.6 ft) thick with a water depth of 150–300 m (490–980 ft) below. Four overlapping drill cores at three sites reflect in excellent quality the geological history and glaciation of the Antarctic during the last 34 million years.
