Simulating the temperature and precipitation signal in an Alpine ice core [PDF]

Climate of the Past, 2013
Accumulation and δ18O data from Alpine ice cores provide information on past temperature and precipitation. However, their correlation with seasonal or annual mean temperature and precipitation at nearby sites is often low.

Novel approach to estimate the water isotope diffusion length in deep ice cores with an application to Marine Isotope Stage 19 in the Dome C ice core [PDF]

The Cryosphere
Accurate estimates of water isotope diffusion lengths are crucial when reconstructing and interpreting water isotope records from ice cores. This is especially true in the deepest, oldest sections of deep ice cores, where thermally enhanced diffusive ...

Thermal Sidewall Ice Corer (TSIC) to recover samples from boreholes drilled in glaciers and ice sheets

Journal of Glaciology
The proposed Thermal Sidewall Ice Corer (TSIC) is designed to accurately sample horizontal ice layers of scientific interest, such as tephra layers, basal ice and shear zones, and retrieve ice cores back to the surface. The system features a bending core

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 ...

Culturable bacteria isolated from seven high-altitude ice cores on the Tibetan Plateau

Journal of Glaciology, 2019
Microorganisms are the most abundant organisms on Earth, and microbial abundance records preserved in ice cores have been connected to records of environmental change.

Consistency of the orbital chronologies derived for Vostok and EPICA DC ice cores based on the dependence of ice air content on local insolation

Лëд и снег
Total air content (TAC) is a multi­proxy property of polar ice, which is thought to contain evidence of past changes in local insolation, summer temperature, meteorological conditions, and the elevation of glaciersat the site of ice formation.

Brief communication: The Danish replicate drilling system – results from the first field test [PDF]

The Cryosphere
We report on the successful test of a new replicate drilling system for ice cores. The test was done in drill fluid, at 140 m depth in the East Greenland Ice Core Project (EastGRIP) borehole in central Greenland.
