Geological investigations in the Falkland Islands Dependencies since 1940
Read more of: Geological investigations in the Falkland Islands Dependencies since 1940Scientific interest in the Falkland Islands Dependencies was revived after a lapse of some years when Operation “Tabarin” was formed in 1943, under the auspices of the Royal Navy. In […]

Examining local time variations in the gains and losses of open magnetic flux during substorms
Read more of: Examining local time variations in the gains and losses of open magnetic flux during substormsThe open magnetic flux content of the magnetosphere varies during substorms as a result of dayside and nightside reconnection. The open flux can be calculated from the area of the […]

On the role of Rossby wave breaking in quasi‐biennial odulation of the stratospheric polar vortex
Read more of: On the role of Rossby wave breaking in quasi‐biennial odulation of the stratospheric polar vortexThe boreal‐winter stratospheric polar vortex is more disturbed when the quasi‐biennial oscillation (QBO) in the lower stratosphere is in its easterly phase (eQBO), and more stable during the westerly phase […]

Understanding past and future changes in northern Fennoscandian snow cover
Read more of: Understanding past and future changes in northern Fennoscandian snow coverIn this project, a combination of field measurements, remote sensing data and regional climate model outputs were used to study recent and projected future changes in Northern Fennoscandian snow cover. […]

Surviving the Antarctic winter – Life stage cold tolerance and ice entrapment survival in the invasive chironomid midge Eretmoptera murphyi.
Read more of: Surviving the Antarctic winter – Life stage cold tolerance and ice entrapment survival in the invasive chironomid midge Eretmoptera murphyi.An insect’s ability to tolerate winter conditions is a critical determinant of its success. This is true for both native and invasive species, and especially so in harsh polar environments. […]

Liverwort-Fungal Associations: Novel Symbioses In Polar Regions?
Read more of: Liverwort-Fungal Associations: Novel Symbioses In Polar Regions?Symbioses between plants and fungi are ubiquitous in terrestrial ecosystems, in which they play key roles in plant nutrient acquisition and the cycling of elements. The plant host provides carbon […]

Preliminary evidence for the role played by south westerly wind strength on the marine diatom content of an Antarctic Peninsula ice core (1980–2010)
Read more of: Preliminary evidence for the role played by south westerly wind strength on the marine diatom content of an Antarctic Peninsula ice core (1980–2010)Winds in the Southern Ocean drive exchanges of heat and carbon dioxide between the ocean and atmosphere. Wind dynamics also explain the dominant patterns of both basal and surface melting […]

Mesospheric winds measured by MF radar with full correlation analysis: error properties and impacts on studies of wind variance
Read more of: Mesospheric winds measured by MF radar with full correlation analysis: error properties and impacts on studies of wind varianceThe mesosphere is one of the most difficult parts of the atmosphere to sample; it is too high for balloon measurements and too low for in situ satellites. Consequently, there […]

Ice front blocking of ocean heat transport to an Antarctic ice shelf
Read more of: Ice front blocking of ocean heat transport to an Antarctic ice shelfMass loss from the Antarctic Ice Sheet to the ocean has increased in recent decades, largely because the thinning of its floating ice shelves has allowed the outflow of grounded […]

Evidence of pathogen-induced immunogenetic selection across the large geographic range of a wild seabird
Read more of: Evidence of pathogen-induced immunogenetic selection across the large geographic range of a wild seabirdOver evolutionary time, pathogen challenge shapes the immune phenotype of the host to better respond to an incipient threat. The extent and direction of this selection pressure depends on the […]

Evidence for cryptic diversity in the “pan-Antarctic” springtail Friesea antarctica and the description of two new species.
Read more of: Evidence for cryptic diversity in the “pan-Antarctic” springtail Friesea antarctica and the description of two new species.The invertebrate terrestrial fauna of Antarctica is being investigated with increasing interest to discover how life interacts with the extreme polar environment and how millions of years of evolution have […]
