Is Vostok lake in steady state? [PDF]

, 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

Incorporation of particulates into accreted ice above subglacial Vostok lake, Antarctica [PDF]

, 2005
The nature of microscopic particulates in meteoric and accreted ice from the Vostok (Antarctica) ice core is assessed in conjunction with existing ice-core data to investigate the mechanism by which particulates are incorporated into refrozen lake water.

Assessment of thermobaric state and change of the mass balance in the subgkacial Lake Vostok after drilling-in

Лëд и снег, 2015
Estimation of temperature and pressure conditions in the subglacial reservoirs is one of the most important tasks of modern subglacial research, since it provides an adequate tool for predicting the process of their accessing.

Salinity impact on water flow and lake ice in Lake Vostok, Antarctica [PDF]

, 2003
Lake Vostok, isolated from direct exchange with the atmosphere for million years, provides a unique and so far inaccessible habitat. By using a numerical model, and recent lake geometry information, the lake circulation was investigated for different ...

Who discovered the Lake Vostok?

Лëд и снег, 2016
A history of the subglacial lake Vostok that had been revealed near this Soviet Antarctic Station is briefly described in the paper. Three participants of the Soviet Antarctic Expeditions played a significant part in the history of the Lake discovery ...

Melting of the glacier base during a small-volume subglacial rhyolite eruption: evidence from Blahnukur, Iceland. [PDF]

, 2002
Although observations of recent volcanic eruptions beneath Vatnajokull, Iceland have improved the understanding of ice deformation and meltwater drainage, little is known about the processes that occur at the glacier base.

Products of an effusive subglacial rhyolite eruption: Blahnukur, Torfajokull, Iceland. [PDF]

, 2001
. We present field observations from Blahnukur, a small volume (400 m thick. Lithofacies associations attest to complex patterns of volcano-ice interaction.

Short-term variability in Greenland Ice Sheet motion forced by time-varying meltwater inputs: implications for the relationship between subglacial drainage system behavior and ice velocity. [PDF]

, 2012
High resolution measurements of ice motion along a 120 km transect in a land-terminating section of the GrIS reveal short-term velocity variations (<1 day), which are forced by rapid variations in meltwater input to the subglacial drainage system from

Analysis of long-term dynamic changes of subglacial lakes in the Recovery Ice Stream, Antarctica [PDF]

The Cryosphere
The dynamic activity of subglacial lakes plays a crucial role in modulating glacial processes and the mass balance of the Antarctic ice sheet. The Recovery Ice Stream (RIS), projected to experience significant mass loss in East Antarctica during coming ...

Discovery of relict subglacial lakes and their geometry and mechanism of drainage

Nature Communications, 2016
Our understanding of subglacial lake drainage events is limited by a lack of direct observations. Here, the authors use ground penetrating radar to identify a relict subglacial lake and infer drainage mechanisms based on geomorphological features.
