Glacier retreat and melt-lake expansion at Stephenson Glacier, Heard Island World Heritage Area

  title={Glacier retreat and melt-lake expansion at Stephenson Glacier, Heard Island World Heritage Area},
  author={Kevin Kiernan and Anne McConnell},
  journal={Polar Record},
  pages={297 - 308}
Abstract Historical records, recent observations, and geomorphological evidence indicate that rates of retreat and downwasting of the tidewater Stephenson Glacier, and concurrent expansion of ice-marginal melt-lakes, has increased by an order of magnitude since 1987. Melt-lake expansion is partly the product of greatly accelerated ablation of older, ice-cored twentieth-century moraines. The timing of these changes broadly coincides with reported increases in atmospheric and sea-surface… Expand
Recent glacier changes and climate trends on South Georgia
Abstract Frontal positions for a sample of 36 out of a potential ca. 160 glaciers on the subantarctic island of South Georgia have been mapped, georeferenced in ArcGIS and analysed for 20th centuryExpand
Submarine sedimentary bedforms and benthos surrounding the Heard and McDonald Islands World Heritage site
We present highlights of the first multibeam and bottom sampling survey surrounding the UNESCO World Heritage listed Heard and McDonald Islands (HIMI), conducted in the HIMI Marine ReserveExpand
Glacial Maximum and the onset of deglaciation on the maritime-Antarctic

Fluvial adjustments in response to glacier retreat: Skaftafellsjökull, Iceland
This study describes changes to the proglacial drainage network of Skaftafellsjokull, Iceland from 1998 to 2011. Proglacial landscapes are highly sensitive to glacier retreat, and the retreat ofExpand
Remote Sensing of Glaciers of the Subantarctic Islands
Through case studies, we summarize progress for the Subantarctic in the drive to complete the World Glacier Inventory. Most of the 29 Heard Island glaciers have shrunk since the first observations inExpand
Changes in Antarctic sea-ice extent from direct historical observations and whaling records
Changes in the extent of Antarctic sea-ice are difficult to quantify for the pre-satellite era. The available direct data are sparse. A substantially larger set of proxy records based on whalingExpand
Antarctic Climate Change and its Influences on Terrestrial Ecosystems
Most global circulation models (GCMs) predict enhanced rates of climate change, particularly temperature increase, at higher latitudes. In the Antarctic terrestrial environment, the severe stressesExpand
Influences on and origins of terrestrial biodiversity of the sub-Antarctic islands
The "sub-Antarctic" is a region of the planet characterised by small and extremely isolated island landmasses set in the vastness and harsh conditions of the Southern Ocean. Although there is noExpand
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 fasterExpand


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 AmericaExpand
Geomorphology of the Sub-Antarctic Australian Territory of Heard Island-McDonald Island
The geomorphology of Heard Island-McDonald Island is primarily the product of close interplay between volcanism, glaciation, and vigorous marine processes in a stormy sub-Antarctic environment. TheExpand
Recent changes in the glaciers of Heard Island
Heard Island, a heavily glacierized volcanic island in the Southern Ocean, is 80% ice-covered, with glaciers descending from 2,400 m to sea level: major glaciers are up to 7 km long with areasExpand
Recent atmospheric warming and retreat of ice shelves on the Antarctic Peninsula
IN 1978 Mercer1 discussed the probable effects of climate warming on the Antarctic Ice Sheet, predicting that one sign of a warming trend in this region would be the retreat of ice shelves on theExpand
The link between climate warming and break-up of ice shelves in the Antarctic Peninsula
Abstract A review of in situ and remote-sensing data covering the ice shelves of the Antarctic Peninsula provides a series of characteristics closely associated with rapid shelf retreat: deeplyExpand
Climate Variability in the Amundsen and Bellingshausen Seas
Satellite data reveal a 20% decline in sea ice extent in the Amundsen and Bellingshausen Seas in the two decades following 1973. This change is negatively correlated with surface air temperatures onExpand
Abrupt mid-twentieth-century decline in Antarctic sea-ice extent from whaling records
A decline in Antarctic sea-ice extent is a commonly predicted effect of a warming climate. Direct global estimates of the Antarctic sea-ice cover from satellite observations, only possible since theExpand
Rapid disintegration of the Wordie Ice Shelf in response to atmospheric warming
THE breaking up of ice shelves around the Antarctic Peninsula has been cited1 as a “sign that a dangerous warming is beginning in Antarctica”. Here we present satellite images showing theExpand
Coastal studies at Heard Island 1992/93: Changes in sea surface temperature and coastal landforms
Sea temperature was measured weekly at Spit Bay, Heard Island, from April 1992 to March 1993. Temperatures were generally higher than those recorded in 1949 (at Atlas Cove), but these sites are notExpand
Climatic change and its ecological implications at a subantarctic island
It is suggested that changing sealevel circulation patterns, by allowing opportunities for colonization by new biota, may have an even more important influence on terrestrial sub-Antarctic ecosystems than is suggested merely on the basis of associated changes in temperature or precipitation. Expand
