Mass-conserving subglacial hydrology in the Parallel Ice Sheet Model version 0.6
Parallel Ice Sheet Model subglacial hydrology
2015/8/6
We describe and test a two-horizontal-dimension
subglacial hydrology model which combines till with a distributed system of water-filled, linked cavities which open
through sliding and close t...
Confirmed: 800 meters beneath Antarctic ice sheet, subglacial lake holds viable microbial ecosystems（图）
The microbial ecosystem ice sheet

B-roll from the WISSARD project is available by contacting Dena Headlee, dheadlee@nsf.gov / (703) 292-7739.
In a finding that has implications for life in other extreme environments, both on Earth an...
Reduced glacier sliding caused by persistent drainage from a subglacial lake
Reduced glacier sliding persistent drainage subglacial lake

We present velocity observations of a glacier outlet in Vatnajökull, Iceland, deduced from interferometric SAR (InSAR) data obtained during the ERS1/2 tandem mission in 1995–2000. More than a 50%...
Interaction between ice sheet dynamics and subglacial lake circulation:a coupled modelling approach
ice sheet dynamics subglacial lake circulation coupled modelling approach
2010/2/3
Subglacial lakes in Antarctica influence to a large extent the flow of the ice sheet. In this study we use an idealised lake geometry to study this impact. We employ a) an improved three-dimensional f...
Quasi-100 ky glacial-interglacial cycles triggered by subglacial burial carbon release
glacial-interglacial cycles subglacial carbon
2008/11/4
A mechanism is proposed in which climate, carbon cycle and icesheets interact with each other to produce a feedback that can lead to quasi-100 ky glacial-interglacial cycles. A central process is the ...
Combination of SAR remote sensing and GIS for monitoring subglacial volcanic activity–recent results from Vatnajökull ice cap (Iceland)
SAR remote sensing GIS subglacial volcanic activity recent results ice cap
2009/12/30
This paper presents latest results from the combined use of SAR (Synthetic Aperture Radar) remote sensing and GIS providing detailed insights into recent volcanic activity under Vatnajökull ice c...
Subglacially-formed debris-rich chemical deposits were found both on bedrock surface and in bedrock crevice on the edge of Qiangyong Glacier, one of the continental glaciers in Tibet. Grai...
Limnological conditions in Subglacial Lake Vostok, Antarctica
Subglacial Lake Vostok Antarctica

waters of the lake. Bacterial density is two- to sevenfold higher in accretion ice than the overlying glacial ice,
implying that Lake Vostok is a source of bacterial carbon beneath the ice sheet. Phy...
