Unusual coastal flood impacts in Salmon Valley, McMurdo Sound, Antarctica
Abstract Large floods bringing significant sediments into the coastal oceans have not been observed in Antarctica. We report evidence of a large flood event depositing over 50 cm of sediment onto the nearshore benthic habitat at Salmon Bay, Antarctica, between 1990 and 2010. Besides direct observati...
