Aberystwyth team's iceberg work to be featured on TV
The moment of birth of an iceberg has been analysed in detail for the first time. Dr Alun Hubbard from Aberystwyth University’s Institute of Geography and Earth Sciences and researchers from the University of St Andrews have completed a detailed and thorough survey of the interface between a large marine-terminating glacier and the ocean. Using a technique called side-scanning-sonar operated from their research vessel Gambo during July 2012, Dr Hubbard and his team from Aberystwyth University mapped changes in the ice-front of Store Glacier on the West Coast of Greenland. This glacier is an outlet for the Greenland ice sheet. Working with Alun Hubbard was Dr Richard Bates from the University of St Andrews who had developed new techniques of data processing that allowed him to compare the ice front before and after a massive iceberg calving event. This enabled him to visualise those changes in detail and make estimates of ice loss from the glacier front over a two-week period. This in...
