A high-resolution bedrock map for the Antarctic Peninsula [PDF]

, 2014
Assessing and projecting the dynamic response of glaciers on the Antarctic Peninsula to changed atmospheric and oceanic forcing requires high-resolution ice thickness data as an essential geometric constraint for ice flow models.

Synoptic mode of Antarctic summer sea ice superimposed on interannual and decadal variability

Advances in Climate Change Research, 2021
In contrast to decreased Arctic sea ice extent, Antarctic sea ice extent shows a somewhat increased trend. There is a large interannual variability of Antarctic sea ice, especially in the Pacific sector of the Southern Ocean.

Biodiversity in mountain soils above the treeline

Biological Reviews, EarlyView.
ABSTRACT Biological diversity in mountain ecosystems has been increasingly studied over the last decade. This is also the case for mountain soils, but no study to date has provided an overall synthesis of the current state of knowledge. Here we fill this gap with a first global analysis of published research on cryptogams, microorganisms, and fauna in ...

Study of the impact of ice formation in leads upon the sea ice pack mass balance using a new frazil and grease ice parameterisation [PDF]

, 2015
Leads are cracks in sea ice that often form due to deformation. During winter months leads expose the ocean to the cold atmosphere resulting in supercooling and the formation of frazil ice crystals within the mixed layer.

Emergence, spread, and impact of high‐pathogenicity avian influenza H5 in wild birds and mammals of South America and Antarctica

Conservation Biology, EarlyView.
Abstract The currently circulating high‐pathogenicity avian influenza (HPAI) virus of the subtype H5 causes variable illness and death in wild and domestic birds and mammals, as well as in humans. This virus evolved from the Goose/Guangdong lineage of the HPAI H5 virus, which emerged in commercial poultry in China in 1996, spilled over into wild birds,

Report on the geomorphological survey in the Soya Coast (JARE-61)

Antarctic Record, 2020
The Antarctic Ice Sheet is a major source of future sea-level rise due to global warming. Reconstruction of the past Antarctic Ice Sheet is essential to understand the mechanism of the Antarctic Ice Sheet response to global and regional climate changes ...

Climate Absurdism

Journal of Applied Philosophy, EarlyView.
ABSTRACT Many arguments in the popular discourse around climate change seem intended to give the impression that climate action is an absurd endeavor. These ‘climate absurdist’ arguments are reflected in the question: ‘if the climate is going to change anyway, why should we care about anthropogenic climate change?’ Classic absurdist philosophy suggests

Rapid Decline of Total Antarctic Sea Ice Extent during 2014–16 Controlled by Wind-Driven Sea Ice Drift

Journal of Climate, 2019
Between 2014 and 2016 the annual mean total extent of Antarctic sea ice decreased by a record, unprecedented amount of 1.6 × 106 km2, the largest in a record starting in the late 1970s. The mechanisms behind such a rapid decrease remain unknown.

Environmental and Evolutionary Forces Shaping Penguin Geographic Limits

Journal of Biogeography, EarlyView.
ABSTRACT Aim Penguins are seabirds exclusively found in the Southern Hemisphere, with their existence dating back to the late Cretaceous. Despite their exceptional dispersal capabilities, which allow them to inhabit a wide range of environments—from polar regions to temperate zones, and even near the Equator—penguins are absent in the Northern ...

A mechanism for biologically-induced iodine emissions from sea-ice

, 2008
International audienceOnly recently, ground- and satellite-based measurements have reported high concentrations of IO in coastal Antarctica. The sources of such a large iodine burden in the Antarctic atmosphere remain unknown.
