Subglacial Lake Ellsworth: a candidate for in situ exploration in West Antarctica [PDF]

, 2004
Radio-echo sounding reveals a 10 km-long lake beneath similar to3.4 km of ice near the Ellsworth Mountains in West Antarctica, 20 km from the ice divide. Subglacial Lake Ellsworth is located within a distinct topographic hollow, which is similar to1.5 km

Switch-off of a major enhanced ice flow unit in East Antarctica [PDF]

, 2006
The East Antarctic Ice Sheet (EAIS) is the largest reservoir of ice on the planet by an order of magnitude. Compared with the West Antarctic Ice Sheet (WAIS), it is traditionally considered to be relatively stable, with only minor adjustments to its ...

Seismicity and neotectonics of West Antarctica [PDF]

Geophysical Research Letters, 2003
Newly discovered earthquakes in West Antarctica provide the first documentation of seismicity in the region. The data presented here indicate that the ice sheet does not suppress seismicity as has been previously proposed. However, the observed earthquake pattern suggests the West Antarctic rift system is no longer actively extending.

The "tipping" temperature within Subglacial Lake Ellsworth, West Antarctica and its implications for lake access. [PDF]

, 2011
We present results from new geophysical data allowing modelling of the water flow within Subglacial Lake Ellsworth (SLE), West Antarctica. Our simulations indicate that this lake has a novel temperature distribution due to significantly thinner ice than ...

The tipping points and early warning indicators for Pine Island Glacier, West Antarctica

The Cryosphere, 2020
. Mass loss from the Antarctic Ice Sheet is the main source of uncertainty in projections of future sea-level rise, with important implications for coastal regions worldwide. Central to ongoing and future changes is the marine ice sheet instability: once

The Ross Sea Dipole – temperature, snow accumulation and sea ice variability in the Ross Sea region, Antarctica, over the past 2700 years [PDF]

Climate of the Past, 2018
High-resolution, well-dated climate archives provide an opportunity to investigate the dynamic interactions of climate patterns relevant for future projections. Here, we present data from a new, annually dated ice core record from the eastern Ross Sea,

Contextualizing the 1997 warm event observed at Patriot Hills in the interior of West Antarctica

Polar Research, 2018
Between 5 and 8 December 1997, the surface air temperature increased up to 3°C in the interior of West Antarctica, at Patriot Hills (PH), located at about 80°08’S, 81°16ʹ W, at an elevation of 855 m a.s.l.

Refractory black carbon (rBC) variability in a 47-year West Antarctic snow and firn core [PDF]

The Cryosphere, 2020
Black carbon (BC) is an important climate-forcing agent that affects snow albedo. In this work, we present a record of refractory black carbon (rBC) variability, measured from a 20 m deep snow and firn core drilled in West Antarctica (79∘55′34.6′′&

Inland extent of the Weddell Sea Rift imaged by new aerogeophysical data [PDF]

, 2013
The Weddell Sea Rift was a major focus for Jurassic extension and magmatism during the early stages of Gondwana break-up and underlies the Weddell Sea Embayment, which separates East Antarctica from a collage of crustal blocks in West Antarctica.

Mineral dust variability in central West Antarctica associated with ozone depletion [PDF]

Atmospheric Chemistry and Physics, 2013
We present here data of mineral dust variability retrieved from an ice core of the central West Antarctic, spanning the last five decades. Main evidence provided by the geochemical analysis is that northerly air mass incursions to the coring site ...
