Influence of the Gulf Stream on the Barents Sea ice retreat and Eurasian coldness during early winter

Environmental Research Letters, 2014
Abnormal sea-ice retreat over the Barents Sea during early winter has been considered a leading driver of recent midlatitude severe winters over Eurasia. However, causal relationships between such retreat and the atmospheric circulation anomalies remains

Topographic and geologic controls on the Northeast Greenland Ice Stream

Annals of Glaciology
The Northeast Greenland Ice Stream (NEGIS) is an elongated feature extending ∼600 km into the interior of the Greenland Ice Sheet. Here, we investigate detailed subglacial topography along the length of the NEGIS to ascertain the characteristics of the ...

Ice-shelf Response to Ice-stream Discharge Fluctuations: I. Unconfined Ice Tongues

, 1988
Ice-stream discharge fluctuations constitute an independent means of forcing unsteady ice-shelf behavior, and their effect must be distinguished from those of oceanic and atmospheric climate to understand ice-shelf change.

Thermal Weakening, Convergent Flow, and Vertical Heat Transport in the Northeast Greenland Ice Stream Shear Margins

Geophysical Research Letters, 2019
Ice streams are bounded by abrupt transitions in speed called shear margins. Some shear margins are fixed by subglacial topography, but others are thought to be self‐organizing, evolving by thermal feedback to ice viscosity and basal drag which govern ...

Spatial topographic roughness of the bed topography of the Northeast Greenland Ice Stream, downstream of the EastGRIP ice core site

The Northeast Greenland Ice Stream (NEGIS) is an elongated feature extending ~600 km into the interior of the Greenland Ice Sheet. Here, we investigate detailed subglacial topography along the length of the NEGIS to ascertain the characteristics of the ...

Antarctic ice stream thickening under Pliocene warmth

Ice streams regulate most ice mass loss in Antarctica. Determining their response to Pliocene warmth could provide insights into their future behaviour, but is hindered by poor representation of subglacial topography in ice-sheet models.

ICE-SHELF RESPONSE TO ICE-STREAM DISCHARGE FLUCTUATIONS: 11. IDEAL RECTANGULAR ICE SHELF

, 2014
. Ice-shelf thickness and velocity anomalies resulting from ice-stream discharge fluctuations are calculated for an ideal ice shelf fed by a single ice stream and confined within a rectangular coastal geometry.
