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.

Antarctic subglacial drilling rig: Part III. Drilling auxiliaries and environmental measures

Annals of Glaciology, 2021
The Antarctic subglacial drilling rig (ASDR) is designed to recover 105 mm-diameter ice cores up to 1400 m depth and 41.5 mm-diameter bedrock cores up to 2 m in length. In order to ensure safe and convenient drilling, drilling auxiliaries are designed to

Rapid Access Ice Drill: a new tool for exploration of the deep Antarctic ice sheets and subglacial geology

Journal of Glaciology, 2016
A new Rapid Access Ice Drill (RAID) will penetrate the Antarctic ice sheets in order to create borehole observatories and take cores in deep ice, the glacial bed and bedrock below.

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.

An early Little Ice Age brackish water invasion along the south coast of the Caspian Sea (sediment of Langarud wetland) and its wider impacts on environment and people [PDF]

, 2015
Caspian Sea level has undergone significant changes through time with major impacts not only on the surrounding coasts, but also offshore. This study reports a brackish water invasion on the southern coast of the Caspian Sea constructed from a multi ...

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.
