RUNNING DEEPSensitive measuring instruments are lowered through pancake ice to sample water at various levels of the ocean from the seafloor to the surface. The densest waters of Antarctica have reduced dramatically over recent decades, in part due to man-made impact on climate, Australian scientists have said. Research suggests that up to 60 percent of ‘Antarctic Bottom Water' – the dense water formed around the edges of the continent that seeps into the deep sea – has disappeared since 1970.PHOTO: AFP
