Macrozooplankton was collected on 65 stations in the surface waters off the Antarctic Peninsula during the Anglo-German Antarctic expedition in February 1982.Composition, abundance and geographical distribution of the major constituents were analyzed.Most abundant species were the euphausiids Euphausia superba and Thysanoessa macrura and the salp Salpa thompsoni.Vertical distribution and diurnal migration of the predominant macrozooplankton species were investigated on two transects in the southern Drake Passage and across the Bransfield Strait, as weil as on two time stations in the vicinity of Elephant Island.Stratified RMT 8 hauls showed that Euphausia frigida, Euphausia triacantha and Salpa thompsoni migrated to the surface during the night, whereas the other taxa did not migrate.
