Rock debris in an Antarctic ice shelf
We have discovered a band of stones and coarse sand in the Ronne Ice Shelf, Antarctica, some 60m above the ice shelf’s base, 40km from its seaward edge and 420km […]

Late Holocene ice-flow reconfiguration in the Weddell sector of West Antarctica
Read more of: Late Holocene ice-flow reconfiguration in the Weddell sector of West AntarcticaHere we report Late Holocene ice sheet and grounding-line changes to the Weddell Sea sector of West Antarctica. Internal radio-echo layering within the Bungenstock Ice Rise, which comprises very slow-flowing […]

Future hot water drilling on Rutford Ice Stream 2004/05
Read more of: Future hot water drilling on Rutford Ice Stream 2004/05Ice streams are major drainage routes, through which much of the ice in Antarctica flows from the continent. They flow at speeds of up to two orders of magnitude greater […]

Fortnightly variations in the flow velocity of Rutford Ice Stream, West Antarctica
Read more of: Fortnightly variations in the flow velocity of Rutford Ice Stream, West AntarcticaMost of the ice lost from the Antarctic ice sheet passes through a few fast-flowing and highly dynamic ice streams(1). Quantifying temporal variations in flow in these ice streams, and […]

Antarctic palaeo-ice streams
Read more of: Antarctic palaeo-ice streamsWe review the geomorphological, sedimentological and chronological evidence for palaeo-icestreams on the continental shelf of Antarctica and use this information to investigate basal conditions and processes, and to identify factors […]

Ice stream or not? Radio-echo sounding of Carlson Inlet, West Antarctica
Read more of: Ice stream or not? Radio-echo sounding of Carlson Inlet, West AntarcticaThe Antarctic Ice Sheet loses mass to the surrounding ocean mainly by drainage through a network of ice streams: fast-flowing glaciers bounded on either side by ice flowing one or […]

Acoustic impedance and basal shear stress beneath four Antarctic ice streams
Read more of: Acoustic impedance and basal shear stress beneath four Antarctic ice streamsThe acoustic impedance of the subglacial material beneath 7.2 km profiles on four ice streams in Antarctica has been measured using a seismic technique. The ice streams span a wide […]

Provenance changes between recent and glacial-time sediments in the Amundsen Sea embayment, West Antarctica: clay mineral assemblage evidence
Read more of: Provenance changes between recent and glacial-time sediments in the Amundsen Sea embayment, West Antarctica: clay mineral assemblage evidenceThe Amundsen Sea embayment is a probable site for the initiation of a future collapse of the West Antarctic Ice Sheet. This paper contributes to a better understanding of the […]

Differences in ice retreat across Pine Island Bay, West Antarctica, since the Last Glacial Maximum: indications from multichannel seismic reflection data. (Short Research Paper 084)
Read more of: Differences in ice retreat across Pine Island Bay, West Antarctica, since the Last Glacial Maximum: indications from multichannel seismic reflection data. (Short Research Paper 084)An understanding of the glacial history of Pine Island Bay (PIB) is essential for refining models of the future stability of the West Antarctic Ice Sheet (WAIS). New multichannel seismic […]

Bayesian estimation of basal conditions on Rutford Ice Stream, West Antarctica, from surface data
Read more of: Bayesian estimation of basal conditions on Rutford Ice Stream, West Antarctica, from surface dataThe determination of basal properties on ice streams from surface data is formulated as a Bayesian statistical inference problem. The theory is applied to a flowline on Rutford Ice Stream, […]

An improved bathymetry compilation for the Bellingshausen Sea, Antarctica, to inform ice-sheet and ocean models
Read more of: An improved bathymetry compilation for the Bellingshausen Sea, Antarctica, to inform ice-sheet and ocean modelsThe southern Bellingshausen Sea (SBS) is a rapidly-changing part of West Antarctica, where oceanic and atmospheric warming has led to the recent basal melting and break-up of the Wilkins ice […]
