Suprabenthic fauna from the Bellingshausen Sea and western Antarctic Peninsula: spatial distribution and community structure
During the austral summers of 2003 and 2006 suprabenthic assemblages were investigated at 35 stations located in the Bellingshausen Sea and off the western Antarctic Peninsula, at depths ranging from 45 to 3280 m. Suprabenthos was collected with a Macer-GIROQ sledge equipped with an automatic openin...
