Scientists using seismic testing at the largest glacier in east Antarctica find massive subglacial lakes beneath its surface — which they say radically alters estimates on predicted sea level rise.Key points:The Totten Glacier is the biggest of four glaciers in east Antarctica
It is named after sailor George Totten, who took part in a US Navy expedition between 1838 to 1842
It is feared continued melting of Antarctic ice will raise sea levels to catastrophic levels
A team of international researchers from the Australian Antarctic Program have this week returned from a 160-day expedition at the Totten Glacier, located near Casey Station — about 3,431 kilometres (2,132 miles) from Hobart.Glaciologist Dr Ben Galton-Fenzi said in order to find out what was underneath, researchers drilled into the ice sheet and set off small explosives about two metres below the surface of the glacier, which is up to 30 kilometres wide and up to two kilometres thick. ____________________________ Of course, why bother with the "scientific method" , consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses. - when you can just check what's Alan Jone's has to say
