The dataset comprises a total of 336 records of abundance and biomass of two sea urchin species, Sterechinus antarcticus Koehler, 1901 and Sterechinus neumayeri (Meissner, 1900), from 67 trawls (Agassiz trawl, bottom trawl or dredge), 56 photo sessions (see doi link to photographs in dataset) and three other samples (multi-box corer, giant box corer, weir basket). The data were collected on the eastern and southern shelf and slope of the Antarctic Weddell Sea (depth range: 97 - 1243 m) during "Polarstern" cruises ANT I/2 (1983), ANT II/4 (1984), ANT III/3 (1985), ANT V/3 (1986), ANT V/4 (1987), ANT VI/3 (1988) and ANT VII/4 (1989). ...
