New records and updated distributional patterns of macroalgae from the South Shetland Islands and northern Weddell Sea, Antarctica
Abstract This study provides new species records (NRs) of macroalgal assemblages present in rocky habitats from the South Shetland Islands (SSI) and north-eastern Antarctic Peninsula (EAP), Weddell Sea. Surveys were conducted during the summers of 2013/2014 to 2017/2018 at Elephant, Deception, Half...
