Abstract
The composition of the planktonic ostracod fauna in the upper 200 m along the Antarctic Peninsula for December/January 1989/90 is described from quantitatively graded RMT 1-hawls. Abundances were low in the entire survey area, possibly due to a mass occurrence of salps. Alacia belgicae and Alacia hettacra were by far the most abundant ostracod species, appearing mainly in the deepest stratum (200 m–140 m). For both species the development stage structure is described and indices for the “mean population stage” are calculated and compared with cited data. An ontogenetic upward migration is indicated.
