Scientists map Antarctic seafloor canyons to help predict climate breakdown

Study suggests the underwater valleys have a major impact on ice loss and ocean circulationScientists have mapped 332 Antarctic canyon networks to help assess the future course of climate breakdown.The research, published in the journal Marine Geology, shows in high resolution submarine valleys that can reach down more than 4,000 metres, more than twice the depth of the Grand Canyon in the US.
