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 ...
In February 2012, Russian ice-core drilling at Lake Vostok accessed the subglacial lake for the first time. [32] Lake water flooded the borehole and froze during the winter season, and the sample of re-frozen lake water (accretion ice) was recovered in the following summer season of 2013.
Lake Vostok (Russian: озеро Восток, romanized: ozero Vostok) is the largest of Antarctica's 675 known [3] subglacial lakes.Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level.
The ice above Lake Vostok, the largest antarctic lake, is approximately 2 miles (3.2 kilometers) thick. Scientists studying the lakes, by careful drilling and water sampling, suggest conditions there may resemble the oceans believed to exist on planet Jupiter 's moon Europa .
An illustration of ice core drilling above subglacial Lake Vostok. These drilling efforts collected re-frozen lake water that has been analyzed to understand the lake's chemistry. Image credit: Nicolle Rager-Fuller / US National Science Foundation (from Subglacial lake)
Thermal drill used to bore into the Greenland ice sheet at Camp Century. During its first quarter century, CRREL researchers and staff were active in the Arctic, Antarctica, Alaska and the Great Lakes, providing climatic history data, addressing resource extraction issues and extending winter navigation.
Ice-seekers have also hiked the 6-plus miles to Williwaw Lakes, including Laura Kottlowski, a Colorado-based skater who traveled to Anchorage to experience the unique conditions and film content ...
Scientific drilling on the continents includes drilling down into solid ground as well as drilling from small boats on lakes. Sampling thick glaciers and ice sheets to obtain ice cores is related but will not be described further here.
