The characteristics and temporal variability of föhn winds at King Edward Point, South Georgia
Sign Up to like & getrecommendations! Published in 2020 at "International Journal of Climatology"
DOI: 10.1002/joc.6366
Abstract: The mountainous subantarctic island of South Georgia lies within the belt of strong westerly winds that blow around the Southern Ocean. Interaction of the prevailing circumpolar westerly winds with the island’s central mountain chain, which… read more here.

DOI: 10.1007/s00227-016-3067-8
Abstract: Inter-annual variability in diet during crèche (December to February) over 22 years (1989–2010) was examined for gentoo penguins Pygoscelis papua breeding at Bird Island, South Georgia (54°00′S, 38°03′W). Overall, diets comprised 51% crustaceans and 49%… read more here.

DOI: 10.1007/s00300-018-2372-8
Abstract: Information is needed on how anomalous environmental conditions affect important Antarctic ecological sentinels during the winter. Using a non-invasive method (scats), the diet of non-breeding gentoo penguins Pygoscelis papua at Bird Island, South Georgia, was… read more here.

DOI: 10.1098/rsos.181227
Abstract: Evaluating how populations are connected by migration is important for understanding species resilience because gene flow can facilitate recovery from demographic declines. We therefore investigated the extent to which migration may have contributed to the… read more here.

DOI: 10.3389/feart.2018.00002
Abstract: A 7000 year-long cirque glacier reconstruction from South Georgia, based on detailed analysis of fine-grained sediments deposited downstream in a bog and a lake, suggests continued presence during most of the Holocene. Glacier activity is… read more here.

DOI: 10.5194/acp-21-7695-2021
Abstract: Abstract. Atmospheric gravity waves (GWs) play an important role in atmospheric dynamics but accurately representing them in general circulation models (GCMs) is challenging. This is especially true for orographic GWs generated by wind flow over… read more here.

Mechanisms of dissolved and labile particulate iron supply to shelf waters and phytoplankton blooms off South Georgia, Southern Ocean
Sign Up to like & getrecommendations! Published in 2017 at "Biogeosciences"
DOI: 10.5194/bg-15-4973-2018
Abstract: The island of South Georgia is situated in the iron (Fe) depleted Antarctic Circumpolar Current of the Southern Ocean. Iron emanating from its shelf system fuels large phytoplankton blooms downstream of the island, but the… read more here.
