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 […]

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 […]
