340 years of atmospheric circulation characteristics reconstructed from an eastern Antarctic Peninsula ice core [PDF]

, 2006
Copyright @ 2006 American Geophysical Union (AGU)Precipitation delivery mechanisms for Dolleman Island (DI), located off the east coast of the Antarctic Peninsula, are investigated using reanalysis and back trajectory data. The Southern Annular Mode (SAM)

Temperature dependence of grain size in Tibetan ice core [PDF]

The Cryosphere
Grain size in ice cores can not only reflect the glacial strain processes but also be linked to climate change. However, the variation of grain size along ice cores in mountain glaciers remains largely unexplored.

The EPICA deep ice cores: first results and perspectives [PDF]

, 2004
Two deep ice cores are being drilled in Antarctica in the frame of the European Project for Ice Coring in Antarctica (EPICA). The Dome C ice core will provide more information about mechanisms of global climatic changes over several climatic cycles.

Twin Ice Cores from Greenland Reveal History of Climate Change, More [PDF]

, 1996
Two projects conducted from 1989 to 1993 collected parallel ice cores—just 30 km apart— from the central part of the Greenland ice sheet. Each core is more than 3 km deep and extends back 110,000 years.

Stratigraphy of sea-ice cores collected in the Eurasian basin during CAATEX 2019 cruise

, 2023
The physical properties of sea ice, including salinity, sea ice temperature, and sea ice texture as well as isotopic composition (oxygen and hydrogen) were analyzed from samples collected on the CAATEX 2019 expedition to the central Arctic Ocean (between

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 ...

Late glacial climate history from ice cores [PDF]

, 1984
Ice cores contain information on climatic variations and their causes. Recent results obtained on the new deep ice core drilled in 1981 at Dye 3, South Greenland, in the frame of the US-Danish-Swiss Greenland Ice Sheet Program, are: - Comparison of

Snow-ice contribution to the structure of sea ice in the Amundsen Sea, Antarctica

Annals of Glaciology, 2020
The widespread occurrence of snow-ice formation on the pack ice plays a critical role in the mass balance of Antarctic sea ice. The stable isotope composition, ice texture and salinity of eight ice cores, obtained from the Amundsen Sea during the Oden ...

Ices in Starless and Starforming Cores [PDF]

Proceedings of the International Astronomical Union, 2011
AbstractIcy grain mantles are commonly observed through infrared spectroscopy toward dense clouds, cloud cores, protostellar envelopes and protoplanetary disks. Up to 80% of the available oxygen, carbon and nitrogen are found in such ices; the most common ice constituents – H2O, CO2 and CO – are second in abundance only to H2 in many star forming ...

Long-term record of H2O2 in polar ice cores [PDF]

, 1986
At Dye 3 and Camp Century, Greenland, and at Byrd Station, West-Antarctica, ice cores were drilled to bedrock. They offer an archive of solid precipitation over the last 50.000 to 100,OOO years.
