Potential seaways across West Antarctica [PDF]
Geochemistry, Geophysics, Geosystems, 2011 The West Antarctic ice sheet (WAIS) has long been considered vulnerable to rapid retreat and today parts are rapidly losing ice. Projection of future change in WAIS is, however, hampered by our poor understanding of past changes, especially during interglacial periods that could be analogs for the future, but which undoubtedly provide an opportunity ...

Climatology and surface impacts of atmospheric rivers on West Antarctica
The Cryosphere, 2023 . Atmospheric rivers (ARs) transport large amounts of moisture from the mid- to high-latitudes and they are a primary driver of the most extreme snowfall events, along with surface melting, in Antarctica.

Energetics of Surface Melt in West Antarctica [PDF]
The Cryosphere, 2020 . We use reanalysis data and satellite remote sensing of cloud properties to examine how meteorological conditions alter the surface energy balance to cause surface melt that is detectable in satellite passive microwave imagery over West Antarctica. This

The sensitivity of West Antarctica to the submarine melting feedback
Geophysical Research Letters, 2017 We use an ice sheet model with realistic initial conditions to forecast how the Amundsen Sea sector of West Antarctica responds to recently observed rates of submarine melting.

Differential distribution of minerals in the proboscis hooks of Corynosoma pseudohamanni Zdzitowiecki, 1984 (Acanthocephala: Polymorphidae) juveniles from Notothenia coriiceps Richardson off Argentine Islands, West Antarctica [PDF]
HelminthologiaCorynosoma pseudohamanni Zdzitowiecki, 1984 (Polymorphidae) was described from the intestinal tract of 5 species of seals, including the type and primary host, the Weddell seal Leptonycotes weddellii (Lesson) in the South Shetlands, West Antarctica ...

Geophysical Monograph Series, Page 1-26., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Magmatism and tectonic evolution of West Antarctica
Dizhi lixue xuebao, 2021 West Antarctica is mainly composed of five distinct micro-continental blocks, namely Haag Nunataks, Antarctic Peninsula, Thurston Island, Marie Byrd Land and Ellsworth-Whitmore Mountains. In order to understand the geological evolution of West Antarctica,

Ice Flow Direction Change in Interior West Antarctica
Science, 2004 Upstream of Byrd Station (West Antarctica), ice-penetrating radar data reveal a distinctive fold structure within the ice, in which isochronous layers are unusually deep. The fold has an axis more than 50 kilometers long, which is aligned up to 45° to the ice flow direction.

Deglacial temperature history of West Antarctica. [PDF]
Proc Natl Acad Sci U S A, 2016 Significance The magnitude and timing of Antarctic temperature change through the last deglaciation reveal key aspects of Earth’s climate system. Prior attempts to reconstruct this history relied on isotopic indicators without absolute calibration.

Observations of iodine monoxide over three summers at the Indian Antarctic bases of Bharati and Maitri [PDF]
Atmospheric Chemistry and Physics, 2021 Iodine plays a vital role in oxidation chemistry over Antarctica, with past observations showing highly elevated levels of iodine oxide (IO) leading to severe depletion of boundary layer ozone in West Antarctica.
