West Antarctica and future sea-level rise: a workshop to identify priorities for research and collaboration in West Antarctica; Royal Society, London 3rd and 4th March 2016 [PDF]

open access: yes, 2016
Since the 1990s, satellites have shown accelerating ice-loss driven by ocean change in the neighbouring glacier basins that drain more than one-third of West Antarctica into the Amundsen Sea.

Change and variability in East antarctic sea ice seasonality, 1979/80-2009/10. [PDF]

open access: yesPLoS ONE, 2013
Recent analyses have shown that significant changes have occurred in patterns of sea ice seasonality in West Antarctica since 1979, with wide-ranging climatic, biological and biogeochemical consequences. Here, we provide the first detailed report on long-

The application of the GPR-method for safety of logistics operations near the Russkaya station in West Antarctica

open access: yesЛëд и снег, 2022
The Russkaya station (Marie Byrd Land, West Antarctica) was one of the wintering stations of the Russian Antarctic Expedition (RAE) before its conservation in 1990.

Lead Sources to the Amundsen Sea, West Antarctica

open access: yesEnvironmental Science & Technology, 2016
The global prevalence of industrial lead (Pb) contamination was exemplified decades ago by the predominance of anthropogenic Pb in samples of Antarctic surface ice and in Southern Ocean surface waters. Decreases in environmental Pb contamination corresponding with the near-global phase-out of leaded automobile gasoline beginning in the 1970s have since

Bayesian multi‐state mark‐resight modeling of survival and cause‐specific mortality from telemetered individuals: European fallow deer in Australia

open access: yesThe Journal of Wildlife Management, EarlyView.
We illustrate how a Bayesian multi‐state mark‐resight (MSMR) modeling approach can be used to estimate survival and cause‐specific mortality probabilities of GPS‐collared European fallow deer in southeastern Australia. Our case study illustrates the flexibility of Bayesian MSMR models for incorporating imperfect detection probability (arising from ...

Past water flow beneath Pine Island and Thwaites glaciers, West Antarctica

open access: yesThe Cryosphere, 2019
. Outburst floods from subglacial lakes beneath the Antarctic Ice Sheet modulate ice-flow velocities over periods of months to years. Although subglacial lake drainage events have been observed from satellite-altimetric data, little is known about their ...

Globally widespread weeds show preadaptation to non‐analogue climates: a common garden approach

open access: yesOikos, EarlyView.
Climatic niche shifts have been documented for plant species introduced into new regions, however the underlying mechanisms are poorly understood. Niche shifts into novel climates are particularly difficult to predict as previous occurrence data cannot reveal whether these novel climates are within species' fundamental niche limits.

Evaluation of the Antarctic Boundary Layer Thermodynamic Structure in MERRA2 Using Dropsonde Observations from the Concordiasi Campaign

open access: yesEarth and Space Science, 2019
Recent high‐resolution dropsonde observations from the 2010 Concordiasi field campaign in austral spring season show that surface‐based inversions (SBIs) over Antarctica are frequently eroded, with well‐mixed boundary layers occurring 33% and 18% of the ...

High-resolution orthophoto map and digital surface models of the largest Argentine Islands (the Antarctic) from unmanned aerial vehicle photogrammetry

open access: yesJournal of Maps, 2020
This study presents the first high-resolution orthophoto maps and digital surface models (DSMs) of the largest Argentine Islands, West Antarctica. Aerial surveys with small unmanned aerial vehicle (UAV) were performed in Austral summer, 2018, taking 10 ...

Phosphorus limits the growth of bacterial and eukaryotic primary producers in recently deglaciated High Arctic soils

open access: yesOikos, EarlyView.
Glaciers are receding at unprecedented rates worldwide, exposing large areas of barren sediment that are quickly colonized by microbes. Nutrient availability is a critical driver of early ecosystem succession, but in the High Arctic its role has remained uncertain.
