Report of the Wintering Party of the 11th Japanese Antarctic Research Expedition in 1970-1971 (Reports of the Japanese Antarctic Research Expedition)

open access: yesAntarctic Record, 1972
1. The 11th Wintering party of the Japanese Antarctic Research Expedition (1969-1971) led by T. MATSUDA consisted of thirty members. The items of the research programmes were as follows : aurora, cosmic rays, geomagnetism, ionosphere, radio physics ...

Hydraulic and mechanical properties of glacial sediments beneath Unteraargletscher, Switzerland: implications for glacier basal motion [PDF]

open access: yes, 2001
The force on a ‘ploughmeter’ and subglacial water pressure have been measured in the same borehole at Unteraargletscher, Switzerland, in order to investigate ice–sediment coupling and the motion at the base of a soft-bedded glacier.

Melting and freezing under Antarctic ice shelves from a combination of ice-sheet modelling and observations

open access: yesJournal of Glaciology, 2017
Ice-shelf basal melting is the largest contributor to the negative mass balance of the Antarctic ice sheet. However, current implementations of ice/ocean interactions in ice-sheet models disagree with the distribution of sub-shelf melt and freezing rates

Change at 85 degrees south: Shackleton Glacier region proglacial lakes from 1960 to 2020

open access: yesAnnals of Glaciology, 2023
Over the last two decades, anomalous warming events have been observed in coastal Antarctic regions. While these events have been documented in the Ross Sea sector, the Antarctic interior is believed to have been buffered from warming.

Deep radiostratigraphy of the East Antarctic plateau: connecting the Dome C and Vostok ice core sites

open access: yesJournal of Glaciology, 2016
Several airborne radar-sounding surveys are used to trace internal reflections around the European Project for Ice Coring in Antarctica Dome C and Vostok ice core sites. Thirteen reflections, spanning the last two glacial cycles, are traced within 200 km

Pure rotational Raman spectroscopy applied to N2/O2 analysis of air bubbles in polar firn

open access: yesJournal of Glaciology, 2021
Earlier gas measurements of firn air (atmosphere in open pore channels) at polar sites have revealed the occurrence of gas fractionation phenomena during bubble close-off, in addition to well-known thermal and gravitational gas separation.

Is Vostok lake in steady state? [PDF]

open access: yes, 2004
Stable-isotope (D and 18O) data from the Vostok (East Antarctica) ice core are used to explore whether or not subglacial Vostok lake is in isotopic steady state. A simple box model shows that the lake is likely to be in steady state on time-scales of the

The control of an uncharted pinning point on the flow of an Antarctic ice shelf

open access: yesJournal of Glaciology, 2016
Antarctic ice shelves are buttressed by numerous pinning points attaching to the otherwise freely-floating ice from below. Some of these kilometric-scale grounded features are unresolved in Antarctic-wide datasets of ice thickness and bathymetry ...

Contributions to the Glaciology of the Antarctic [PDF]

open access: yesJournal of Glaciology, 1956
AbstractDuring a winter in Terre Adélie in 1951 (Antarctica) certain glaciological studies were made. These were strongly hampered by the extraordinary strength and persistence of the blizzards from the ice cap. Near the coast the wind dominates the distribution of snow completely. The firn limit on the open ice cap is at a height of 450 m. (1500 ft.).

'Calving laws', 'sliding laws' and the stability of tidewater glaciers [PDF]

open access: yes, 2007
A new calving criterion is introduced, which predicts calving where the depth of surface crevasses equals ice height above sea level. Crevasse depth is calculated from strain rates, and terminus position and calving rate are therefore functions of ice ...
