Deep ice coring at Dome Fuji Station, Antarctica [PDF]

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.

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 ...

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 ...

Design and analysis of deepwater tension sensors for ice drill application

Annals of Glaciology, 2021
Monitoring the tension in cables is significant in some ice drill and deepwater applications. Take our RECoverable Autonomous Sonde (RECAS) for example. It is able to melt a hole to the bottom of ice sheet and is able to move upwards.

Drilling the new 5G-5 branch hole at Vostok Station for collecting a replicate core of old meteoric ice

Annals of Glaciology, 2021
Recent studies have shown that stratigraphically disturbed meteoric ice bedded at Vostok Station between 3318 and 3539 m dates back to 1.2 Ma BP and possibly beyond.

Deep ice core drilling to a depth of 3035.22 m at Dome Fuji, Antarctica in 2001–07

Annals of Glaciology, 2021
The Japanese second deep ice coring project was carried out at Dome Fuji, Antarctica. Following the drilling of the pilot hole in 2001, deep ice core drilling led by the Japanese Antarctic Research Expedition (JARE) was conducted over four austral summer

Warm ocean is eroding West Antarctic Ice Sheet [PDF]

, 2004
Satellite radar measurements show that ice shelves in Pine Island Bay have thinned by up to 5.5 m yr^{-1} over the past decade. The pattern of shelf thinning mirrors that of their grounded tributaries-the Pine Island, Thwaites and Smith glaciers- and ...

Coring disturbances in IODP piston cores with implications for offshore record of volcanic events and the Missoula megafloods [PDF]

, 2014
Piston cores collected from IODP drilling platforms (and its predecessors) provide the best long-term geological and climatic record of marine sediments worldwide. Coring disturbances affecting the original sediment texture have been recognized since the

New modeling of the Vostok ice flow line and implication for the glaciological chronology of the Vostok ice core [PDF]

, 2004
We have used new spaceborne (elevation) and airborne (ice thickness) data to constrain a 2D1/2 model of snow accumulation and ice flow along the Ridge B-Vostok station ice flow line (East Antarctica).

Towards ice core sampling by subsea robotic vehicles [PDF]

Geoscientific Instrumentation, Methods and Data Systems
Ice coring has developed into one of the most frequently used sampling methods across cryospheric sciences. Sea ice, firn and glacial ice are sampled using a range of different coring systems.
