Abstract Using archival photography and satellite imagery, we have analysed the rates of advance or retreat of 103 coastal glaciers on South Georgia from the 1950s to the present. Ninety-seven percent of these glaciers have retreated over the period for which observations are available. The average rate of retreat has increased from 8 Ma-1 in the 1950s to 35 Ma-1 at present. The largest retreats have all taken place along the north-east coast, where retreat rates have increased to an average of… 
Estimating Ice Thickness in South Georgia from SRTM Elevation Data
Detailed study of the glaciology of South Georgia is hampered by lack of measurements of the thickness of the ice, because of the logistic difficulties of operating on South Georgia, there are no conventional ice thickness measurements from drilling, radar or seismic techniques, and it is unlikely that these are available in the near future.
Glacier changes on South Georgia since the late-19th century documented in historical photographs
South Georgia is one of the few landmasses in the Southern Ocean. It provides a crucial geographical datapoint for glacier responses to climate change over different timescales. As part of an ongoing
Fluctuation of Glacial Retreat Rates in the Eastern Part of Warszawa Icefield, King George Island, Antarctica, 1979-2018
Assessment of changes in glacier margin positions between 1979 and 2018 in the Antarctic Specially Protected Area 128 (ASPA-128) on King George Island, South Shetland Islands, Antarctica suggests that glacier retreat rates were fastest between 1989–2001 and 2007–2011, with reduced retreat rates between 2001 and 2007.
Long-term demise of sub-Antarctic glaciers modulated by the Southern Hemisphere Westerlies
New high-resolution reconstructions of long-term changes in the extents of three glaciers on the island of South Georgia are presented, combining detailed analyses of glacial-derived sediments deposited in distal glacier-fed lakes and cosmogenic exposure dating of moraines.
Cirque Glacier on South Georgia Shows Centennial Variability over the Last 7000 Years
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
Holocene glacier fl uctuations
A global overview of glacier advances and retreats (grouped by regions and by millennia) for the Holocene is compiled from previous studies. The reconstructions of glacier fluctuations are based on
Holocene glacier fluctuations
Detailed quantification of glacier elevation and mass changes in South Georgia
Most glaciers in South America and on the Antarctic Peninsula are retreating and thinning. They are considered strong contributors to global sea level rise. However, there is a lack of glacier mass
The characteristics and temporal variability of föhn winds at King Edward Point, South Georgia
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
Föhn winds on South Georgia and their impact on regional climate
Average summer temperatures over South Georgia have risen by 1°C along with an increase in the rate of glacial retreat since the 1920s. Glaciers on the northeast of the island are retreating faster


Recent glacier changes and climate trends on South Georgia
Glacier fluctuations on South Georgia during the 1970s and early 1980s
South Georgia is a highly glacierized island with a range of glacier types including corrie, valley and tidewater ice bodies. Glaciologically, it occupies a strategic location between South America
Retreating Glacier Fronts on the Antarctic Peninsula over the Past Half-Century
The continued retreat of ice shelves on the Antarctic Peninsula has been widely attributed to recent atmospheric warming, but there is little published work describing changes in glacier margin
Feral Brown rats, Rattus norvegicus, in South Georgia (South Atlantic Ocean)
Brown rats were introduced to the sub-antarctic island of South Georgia probably around 1800 and are now widespread and abundant, particularly on the north coast, and dependent on tussock grass for their survival.
Status and distribution of wandering, black-browed and grey-headed albatrosses breeding at South Georgia
To determine the status of the total South Georgia population, all known colonies were censused in 2003/2004 using a combination of yacht-based digital photography and ground counts to identify wandering, black-browed and grey-headed albatrosses.
Biological invasions in the Antarctic: extent, impacts and implications
Alien microbes, fungi, plants and animals occur on most of the sub‐Antarctic islands and some parts of the Antarctic continent. These have arrived over approximately the last two centuries,
Defining eradication units to control invasive pests
A molecular genetic approach to the identification of populations suitable for eradication (eradication units) was applied to provide a new tool to assist the management of brown rats Rattus norvegicus on South Georgia to illustrate the developing array of applied ecological issues in which molecular techniques can help guide management.
The SCAR READER Project: toward a high-quality database of mean Antarctic meteorological observations
A new dataset of monthly and annual mean near-surface climate data (temperature, surface and mean sea level pressure, and wind speed) for the Antarctic region has been created using historical
Norway rats (Rattus norvegicus) on the noises and Motukawao Islands, Hauraki Gulf, New Zealand
Histological examination of females showed that, compared with urban and rural Norway rats, maturity was delayed, litters were small and some females ovulated but failed to breed, and potential factors limiting rat numbers on the Noises are discussed, especially shortages of protein-rich foods and fresh water.
