Where to find 1.5 million yr old ice for the IPICS "Oldest-Ice" ice core [PDF]

Climate of the Past, 2013
The recovery of a 1.5 million yr long ice core from Antarctica represents a keystone of our understanding of Quaternary climate, the progression of glaciation over this time period and the role of greenhouse gas cycles in this progression. Here we tackle

New synthetic fiber armored cable for freezing-in thermal ice probes

Annals of Glaciology, 2021
A series of new synthetic armored cables were developed and tested to ensure that they were suitable for use with the RECoverable Autonomous Sonde (RECAS), which is a newly designed freezing-in thermal ice probe.

Where is the 1-million-year-old ice at Dome A? [PDF]

The Cryosphere, 2018
Ice fabric influences the rheology of ice, and hence the age–depth profile at ice core drilling sites. To investigate the age–depth profile to be expected of the ongoing deep ice coring at Kunlun station, Dome A, we use the depth-varying anisotropic ...

Antarctic subglacial drilling rig: Part IV. Electrical and electronic control system

Annals of Glaciology, 2021
In many cases, the efficiency and safety of a drilling project depend on the reliability of the electrical and electronic control system, as the process progresses without visual access of the operator.

Second-year sea-ice salinity, temperature, density, oxygen and hydrogen isotope composition from the main coring site (MCS-SYI) during MOSAiC legs 1 to 4 in 2019/2020

, 2023
Second-year sea-ice thickness, draft, salinity, temperature, and density were measured during near-weekly surveys at the main second-year ice coring site (MCS-SYI) during the MOSAiC expedition (legs 1 to 3) and new second-year ice coring site leg 4 ...

Experimental results on improved JARE deep ice core drill-Experiments in Rikubetsu, Hokkaido in 2002 -

Antarctic Record, 2002
Deep ice coring to bedrock (3028m in depth) at Dome Fuji Station is planned during three successive summer seasons starting from 2003/2004. An improved JARE deep ice core drill (12.2m in length and 3.8m in maximum core length) was developed in December ...

Synchronizing ice cores from the Renland and Agassiz ice caps to the Greenland Ice Core Chronology [PDF]

Journal of Geophysical Research: Atmospheres, 2008
Four ice cores from the Agassiz ice cap in the Canadian high arctic and one ice core from the Renland ice cap in eastern Greenland have been synchronized to the Greenland Ice Core Chronology 2005 (GICC05) which is based on annual layer counts in the DYE‐3, GRIP and NGRIP ice cores.
