Photosynthetic responses of three common mosses from continental Antarctica [PDF]

open access: yes, 2005
Predicting the effects of climate change on Antarctic terrestrial vegetation requires a better knowledge of the ecophysiology of common moss species. In this paper we provide a comprehensive matrix for photosynthesis and major environmental parameters ...

Meteorology of the Antarctic Region [PDF]

open access: yesNature, 1882
IT is well known that on the Antarctic lands perpetual snow descends much lower than in corresponding latitudes of the northern hemisphere. The chief cause of this is, no doubt, the difference of climate due to the preponderance of land in the northern hemisphere and of water in the southern.

Revisiting the mass balance of Bennett Island glaciation, East Siberian Sea

open access: yesArctic, Antarctic, and Alpine Research
Bennett Island is located between the East Siberian Sea and the Arctic Ocean and is part of the De Long archipelago, which is the easternmost location in the high Arctic where terrestrial glaciation exists.

Automated Mapping of Antarctic Supraglacial Lakes Using a Machine Learning Approach

open access: yesRemote Sensing, 2020
Supraglacial lakes can have considerable impact on ice sheet mass balance and global sea-level-rise through ice shelf fracturing and subsequent glacier speedup.

Fourteen degrees of latitude and a continent apart: comparison of lichen activity over two years at continental and maritime Antarctic sites [PDF]

open access: yes, 2010
There are marked declines in precipitation, mean temperatures and the number of lichen species with increasing latitude in Antarctica. However, it is not known which factors are the predominant controllers of biodiversity changes.

Influence of sea-ice anomalies on Antarctic precipitation using source attribution in the Community Earth System Model [PDF]

open access: yesThe Cryosphere, 2020
We conduct sensitivity experiments using a general circulation model that has an explicit water source tagging capability forced by prescribed composites of pre-industrial sea-ice concentrations (SICs) and corresponding sea surface temperatures (SSTs) to

Psychological changes arising from an Antarctic stay: systematic overview

open access: yesEstudos de Psicologia (Campinas)
Long-term stays in extreme environments, such as Polar Regions, may cause significant changes in the health and well-being of individuals. A systematic overview aimed to map studies about the psychological effects on Antarctic expeditioners. The reviewed

Along‐Slope Variability of Cross‐Slope Eddy Transport in East Antarctica

open access: yesGeophysical Research Letters, 2019
Circumpolar Deep Water (CDW) transport across the Antarctic continental slope regulates the delivery of heat to the shelf and its availability to melt floating ice shelves. The cross‐slope density field, calculated from profiles collected by conductivity‐

On-site and in situ remediation technologies applicable to petroleum hydrocarbon contaminated sites in the Antarctic and Arctic [PDF]

open access: yesPolar Research, 2015
Petroleum hydrocarbon contaminated sites, associated with the contemporary and legacy effects of human activities, remain a serious environmental problem in the Antarctic and Arctic.

PRELIMINARY LONG-PERIOD MAGNETOTELLURIC INVESTIGATION AT THE EDGE OF ICE SHEET IN EAST ANTARCTICA [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2020
The lithospheric mantle structure of the Antarctic continent is of great significance of studying the polymerization and fragmentation mechanism of Gondwana and the plate movement law. Long-period magnetotelluric (LMT) is an important method to study the
