Experimental Study on the Insulation Layer Thickness of a Novel Ice Coring Device in Loose Sandstone-Type Uranium Deposits

Energies, 2021
The target strata of sandstone-type uranium deposits are usually located in the fragile and loose strata, which makes it difficult to obtain core samples; consequently, a novel ice coring device for loose sandstone-type uranium deposits is proposed to ...

Deep ice coring at Dome Fuji Station, Antarctica

Antarctic Record, 1999
Deep ice coring was carried out at Dome Fuji Station, Antarctica in 1995 and 1996 following a pilot borehole drilled and cased with FRP pipes in 1993,and reached 2503.52m in December 1996.

An affordable and miniature ice coring drill for rapid acquisition of small iceberg samples [PDF]

HardwareX, 2020
Icebergs account for approximately half of the freshwater flux from the Greenland Ice Sheet and they can impact marine ecosystems by releasing nutrients and sediments into the ocean as they drift and melt.

Coring of Antarctic Subglacial Sediments

Journal of Marine Science and Engineering, 2019
Coring sediments in subglacial aquatic environments offers unique opportunities for research on paleo-environments and paleo-climates because it can provide data from periods even earlier than ice cores, as well as the overlying ice histories ...

Theoretical and numerical simulation research about annular nozzle parameters influence on heat transfer in hot-water ice-coring drilling

Case Studies in Thermal Engineering, 2023
Ice cores from polar zones could determine ice dating and biodiversity. Ice cores retrieved in hot-water ice-coring drilling partly melted owing to moderate drilling speed of annular drill head with many nozzles, which was largely depended on the heat ...

Shallow ice coring and borehole casing at Dome Fuji Station, East Antarctica

Antarctic Record, 1995
A Deep Ice Coring Project at Dome Fuji, East Antarctica has been conducted by the Japanese Antarctic Research Expedition (JARE) since 1992. Shallow ice coring of 112m in depth and casing of its borehole at Dome Fuji Station were carried out in December ...

The future of ice coring: International Partnerships in Ice Core Sciences (IPICS) [PDF]

PAGES news, 2006
Ice cores provide information about past climate and environmental conditions on timescales from decades to hundreds of millennia, and direct records of the composition of the atmosphere. As such, they are cornerstones of global change research. For example, ice cores play a central role in showing how closely climate and greenhouse gas concentrations ...
