More of the Totten Glacier is floating on the ocean than previously thought, increasing its potential to contribute to global sea level rise. Glaciologist, Dr Ben Galton-Fenzi, said the Totten Glacier is one of the fastest flowing and largest glaciers in Antarctica and until now scientists thought more of it was grounded on Antarctic bedrock. As part of the Australian Antarctic Program, Dr Galton-Fenzi’s team of researchers, including scientists from the Australian Antarctic Division, University of Tasmania’s Institute for Marine and Antarctic Studies, and the Central Washington University, spent the summer in Antarctica studying the Totten. Professor Paul Winberry, from Central Washington University, said seismology allowed them to determine the structure of the earth below the surface of the glacier. Read more here
