I am saddened by this tragic news. Being thrown in to the 2 degree C ocean water without survival suits means most likely having immediate heart attack or losing consciousness within few minutes due to hypothermia… The cold Southern Ocean is unforgiving. They didn’t even have a chance to call up for SOS and sank so quick. The sea was relatively calm. 1m wave height at that time sounds to be amazingly calm for this.
