"A massive underwater canyon has been discovered in #Antarctica by acousticians on board icebreaker RSV #Nuyina. The canyon was discovered when wild weather forced resupply work at #CaseyResearchStation to be temporarily suspended... Rather than sit and wait, they decided to use the time to map the #seafloor... What they found was remarkable – a 2100 m-deep canyon, extending more than 46 kilometres off the glacier front."
