报告人简介：
Paul Carling is an Emeritus Professor at the University of Southampton, a Visiting Professor at Lancaster, UK, and a Visiting Professor at Chengdu University of Technology, China.
Paul's interests are diverse. He is currently interested in the dynamics of anastomosed rivers, palaeofloods - especially Quaternary megafloods, a Quaternary meteorite impact in SE Asia and desert river dynamics. Current projects include: 1) Application of graph theory to pattern analysis of anastomosed river networks; 2) Palaeofloods in China, including recent developments along the Tsangpo and Parlung Rivers in Tibet. 3) Lake drainage history recorded in the palaeoshorelines of ice-dammed lakes, Altai, Siberia; 4) Glacier surging in the Karakorum and the prediction of glacial lake outburst floods (GLOFs); 5) Stratigraphic signature of the 800ka Quaternary meteorite impact in Indochina; 6) Erosion history of mountains in Eastern Egyptian Desert, flooding history in wadis and alluvial fans as indicators of past climate change in Egypt, Israel and Jordan; 7) Gravel bedforms and ventifacts in Iceland.
报告内容简介：
Being a geomorphologist is similar to being a police detective investigating a crime. Usually only partial evidence can be found and the detective has to use experience and common sense to recreate the ‘crime scene’ and decide what happened and when did it happen. Who was responsible? In the case of the geomorphologist it is not ‘Who’ but ‘What process’ was involved.
The English Lake District in northern England is a beautiful scenic location and a National Park. This region was glaciated during the last Ice Age with glaciers radiating outwards like spokes in a wheel from central ice caps. The area just to the east is less well known and in contrast was an area of complex ice flows, where local ice and interacted with ice from the Lake District as well as competing for space with Scottish ice and ice in the east on the Pennine hills. The landscape we see today consists of inherited landforms developed before the Ice Age that have been modified during the Ice Age and changed again during the Holocene. This talk will explain how I have tried to unravel the Ice Age story in this region using the field evidence gathered during field trips in the area, interpreting remote-sensing images and piecing together fragmentary information in the scientific literature.
