Microorganisms in the atmosphere over Antarctica
Antarctic microbial biodiversity is the result of a balance between evolution, extinction and colonization, and so it is not possible to gain a full understanding of the microbial biodiversity of […]

Antarctic subglacial lake exploration: a new frontier in microbial ecology
Read more of: Antarctic subglacial lake exploration: a new frontier in microbial ecologyTo date, wherever life has been sought on Earth, it has almost always been found—from high in the stratosphere (Imshenetskii et al., 1975, 1978, 1986; Wainwright et al., 2003) to […]

Current status of the Antarctic herb tundra formation in the central Argentine Islands
Read more of: Current status of the Antarctic herb tundra formation in the central Argentine IslandsChanges in the higher plant populations of the Argentine Islands over the last four to five decades have been central to developing an understanding of the likely biological responses to […]

Frost flower surface area and chemistry as a function of salinity and temperature
Read more of: Frost flower surface area and chemistry as a function of salinity and temperatureFrost flowers play a role in air-ice exchange in polar regions, contribute to tropospheric halogen chemistry, and affect ice core interpretation. Frost flowers were observed and collected on the Hudson […]

Morphology of the upper continental slope in the Bellingshausen and Amundsen Seas – implications for sedimentary processes at the shelf edge of West Antarctica
Read more of: Morphology of the upper continental slope in the Bellingshausen and Amundsen Seas – implications for sedimentary processes at the shelf edge of West AntarcticaSwath bathymetric and sub-bottom profiler data reveal a variety of submarine landforms such as gullies, slide scars, subtle shelf edge-parallel ridges and elongated depressions, and small debris flows along the […]

Ice-ocean processes over the continental shelf of the southern Weddell Sea, Antarctica: a review
Read more of: Ice-ocean processes over the continental shelf of the southern Weddell Sea, Antarctica: a reviewInteractions between the Southern Ocean and the Weddell Sea ice shelves are important both to the Antarctic Ice Sheet and to the production of globally significant water masses. Here we […]

Responses of plants in polar regions to UVB exposure: a meta-analysis
Read more of: Responses of plants in polar regions to UVB exposure: a meta-analysisWe report a meta-analysis of data from 34 field studies into the effects of ultraviolet B (UVB) radiation on Arctic and Antarctic bryophytes and angiosperms. The studies measured plant responses […]

Climate spectrum estimation in the presence of timescale errors
Read more of: Climate spectrum estimation in the presence of timescale errorsWe introduce an algorithm (called REDFITmc2) for spectrum estimation in the presence of timescale errors. It is based on the Lomb-Scargle periodogram for unevenly spaced time series, in combination with […]

Recurrent substorm activity during the passage of a corotating interaction region
Read more of: Recurrent substorm activity during the passage of a corotating interaction regionRecent observations of magnetospheric dynamics driven by interaction with both high-speed solar wind streams (HSSs) and interplanetary coronal mass ejections (ICMEs) have shown periodic substonns to be common under strong […]

A superposed epoch analysis of auroral evolution during substorm growth, onset and recovery: open magnetic flux control of substorm intensity
Read more of: A superposed epoch analysis of auroral evolution during substorm growth, onset and recovery: open magnetic flux control of substorm intensityWe perform two superposed epoch analyses of the auroral evolution during substorms using the FUV instrument on the Imager for Magnetopause-to-Aurora Global Explorer ( IMAGE) spacecraft. The larger of the […]

Limitation of egg production in Calanus finmarchicus in the field: a stoichiometric analysis
Read more of: Limitation of egg production in Calanus finmarchicus in the field: a stoichiometric analysisThe egg production of marine copepods correlates with a range of variables, including the availability of organic carbon (C), nitrogen (N) and the polyunsaturated fatty acids (PUFAs) 20:5(n-3) (EPA) and […]
