Assessing the continuity of the blue ice climate record at Patriot Hills, Horseshoe Valley, West Antarctica [PDF]

open access: yes, 2016
We use high resolution Ground Penetrating Radar (GPR) to assess the continuity of the Blue Ice Area (BIA) horizontal climate record at Patriot Hills, Horseshoe Valley, West Antarctica.

Analytical solutions for the surface response to small amplitude perturbations in boundary data in the shallow-ice-stream approximation [PDF]

open access: yesThe Cryosphere, 2008
New analytical solutions describing the effects of small-amplitude perturbations in boundary data on flow in the shallow-ice-stream approximation are presented.

Tides and the flow of Rutford Ice Stream, West Antarctica [PDF]

open access: yes, 2007
[1] Surface speeds of Rutford Ice Stream, West Antarctica, are known to vary by around 10–20% (depending on location) with a fortnightly periodicity corresponding to a springneap tidal cycle. The reasons for these periodic variations in flow are unclear.

Estimation of ice fabric within Whillans Ice Stream using polarimetric phase-sensitive radar sounding

open access: yesAnnals of Glaciology, 2020
Here we use polarimetric measurements from an Autonomous phase-sensitive Radio-Echo Sounder (ApRES) to investigate ice fabric within Whillans Ice Stream, West Antarctica.

Ice stream behaviour and deglaciation of the Scandinavian Ice Sheet in the Kuittijärvi area, Russian Karelia [PDF]

open access: yesBulletin of the Geological Society of Finland, 2008
Glacial landforms of the Lake Kuittijärvi area, Russian Karelia, which covers an area of more than 7000 km2 , were studied in detail using aerial photography and satellite imagery methods and on-site field observations.

An ice-sheet scale comparison of eskers with modelled subglacial drainage routes [PDF]

open access: yes, 2015
Eskers record the signature of channelised meltwater drainage during deglaciation providing vital information on the nature and evolution of subglacial drainage.

Insights into ice stream dynamics through modelling their response to tidal forcing [PDF]

open access: yesThe Cryosphere, 2014
The tidal forcing of ice streams at their ocean boundary can serve as a natural experiment to gain an insight into their dynamics and constrain the basal sliding law.

TWT and ice thickness of the North East Greenland Ice Stream (tabular data)

open access: yes, 2023
Here, we present a record of more than 8000 km of radar survey lines of radio echo sounding data covering an area of 24 000 km2 centred on the drill site for the East Greenland Ice-core Project (EGRIP) in the central part of the North East Greenland Ice ...

A stratigraphic link across 1100 km of the Antarctic Ice Sheet between the Vostok ice-core site and Titan Dome (near South Pole) [PDF]

open access: yes, 2000
Isochronous internal ice-sheet layering, measured from airborne 60 MHz radar, was traced between Lake Vostok and the Titan Ice Dome (100 km from South Pole Station), Antarctica. Three layers were selected between Ridge B and Titan Dome, and between Ridge

Bedrock controls on subglacial landform distribution and geomorphological processes : evidence from the Late Devensian Irish Sea Ice Stream [PDF]

open access: yes, 2010
Ice streams play an important role as regulators of the behaviour of modern ice sheets, taking the form of corridors of fast flowing ice. Similar zones of fast moving ice have also been recognised draining the margins of the Late Devensian British and ...
