Late Cenozoic unification of East and West Antarctica [PDF]

Nature Communications, 2018
The West Antarctic rift system, which divides the East and West Antarctic plates, was believed to be active until 26 Myr. Here, the authors demonstrate through new geophysical data that rifting within the West Antarctic rift system lasted until 11 Myr ...

Seasonal temperatures in West Antarctica during the Holocene. [PDF]

Nature, 2023
The recovery of long-term climate proxy records with seasonal resolution is rare because of natural smoothing processes, discontinuities and limitations in measurement resolution.

Inter-decadal climate variability induces differential ice response along Pacific-facing West Antarctica. [PDF]

Nat Commun, 2023
Systematic satellite, ocean and atmosphere records show the pace and extent of melting in West Antarctica vary by location, with glaciers flowing to the Amundsen Sea most sensitive to atmosphere‒ocean variability atop a marine ice-sheet instability. West

Antarctic Peninsula warming triggers enhanced basal melt rates throughout West Antarctica. [PDF]

Sci Adv, 2022
The observed acceleration of ice shelf basal melt rates throughout West Antarctica could destabilize continental ice sheets and markedly increase global sea level.

Neogene plant macrofossils from West Antarctica reveal persistence of Nothofagaceae forests into the early Miocene [PDF]

Communications Earth & Environment
The extinction of woody vegetation in Antarctica remains difficult to constrain due to its fragmented macrofossil record. Despite its long-standing polar position, Antarctica hosted extensive vegetation throughout the Paleogene.

Widespread seawater intrusions beneath the grounded ice of Thwaites Glacier, West Antarctica. [PDF]

Proc Natl Acad Sci U S A
Significance We present evidence for seawater intrusions occurring at tidal frequencies over many kilometers beneath the grounded ice of Thwaites Glacier, West Antarctica, a major contributor to sea level rise.

Subglacial lakes and hydrology across the Ellsworth Subglacial Highlands, West Antarctica [PDF]

The Cryosphere, 2020
Subglacial water plays an important role in ice sheet dynamics and stability. Subglacial lakes are often located at the onset of ice streams and have been hypothesised to enhance ice flow downstream by lubricating the ice–bed interface.

Heterogeneous retreat and ice melt of Thwaites Glacier, West Antarctica. [PDF]

Sci Adv, 2019
The heterogeneous retreat of Thwaites glacier indicates complexities of ice melt processes taking place at the grounding zone. The glaciers flowing into the Amundsen Sea Embayment, West Antarctica, have undergone acceleration and grounding line retreat ...

Seasonality and Dynamics of Atmospheric Teleconnection from the Tropical Indian Ocean and the Western Pacific to West Antarctica

Atmosphere, 2021
The global impact of the tropical Indian Ocean and the Western Pacific (IOWP) is expected to increase in the future because this area has been continuously warming due to global warming; however, the impact of the IOWP forcing on West Antarctica has not ...

January 2016 extensive summer melt in West Antarctica favoured by strong El Niño. [PDF]

Nat Commun, 2017
Over the past two decades the primary driver of mass loss from the West Antarctic Ice Sheet (WAIS) has been warm ocean water underneath coastal ice shelves, not a warmer atmosphere.
