Deep-diving robots will venture kilometres under the Southern Ocean’s surface to determine how it is holding up in the face of climate change in the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Investigator’s longest ever voyage. The 10-year-old research vessel on Jan. 5 set off on a 9260km round-trip journey, which was due to take it about 2300km from Hobart to the Southern Ocean and sea-ice edge before it returns to Fremantle in Western Australia in early March. The 60-day venture—led by scientists from the Australian Antarctic Program Partnership and CSIRO—was intended to investigate why deep ocean currents near Antarctica were slowing down and whether the Southern Ocean would continue to absorb heat and carbon dioxide....
