The project aims to reconstruct the glacial history of this important and changing region, looking at glacier responses to environmental change throughout the Cenozoic, but particularly at the Last Glacial Maximum, through the Holocene and into the twentieth century. Using cosmogenic nuclide dating, the scientists will develop a terrestrial chronology for the deglaciation of the eastern margin of the ice sheet. We will determine whether local ice caps behaved synchronously or independently of the Antarctic Peninsula Ice Sheet. The geographical focus of this project is James Ross Island, Vega Island and the adjacent Antarctic Peninsula. These areas have a well-preserved terrestrial record of deglaciation, but one which is largely unexploited.
This project involves investigators from the Centre of Glaciology, Aberystwyth University, and from the Universities of Leeds and Leicester. This NERC-funded project began in April 2010 and will run until April 2014, and has so far involved two field seasons to James Ross Island, NE Antarctic Peninsula, in January 2011 and March 2012. The team went to northern James Ross Island, where the large area of ice-free land will aid their geological investigations. Cosmogenic nuclide dating of rock samples provides chronostratigraphical control for geomorphologically-constrained palaeo-ice sheet reconstructions. Future field plans include visits to Alexander Island, southwest Antarctic Peninsula.
James Ross Island is of particular interest, because until 1995 it was connected to the Antarctic Peninsula by the Prince Gustav Ice Shelf. This was once connected to the Larsen Ice Shelf, but has been retreating since polar exploration began in the late Nineteenth Century. In 1995, it collapsed and disappeared very rapidly, and the ice-shelf glaciers have become tidewater (marine-terminating) glaciers with grounded, partially floating or floating ice margins. Of particular interest are the events building up to the collapse of the ice shelf, structural controls on its collapse, and the response of tributary glaciers to ice-shelf collapse, 15 years after the event.
Hello My sons name is James Ross and he is 6 and he thinks it’s very cool ? that he has an island with the same name as him
That is very cool!
