Abundance of gelatinous carnivores in the nekton community of the Antarctic Polar Frontal Zone in summer 1994
9 pages, 4 figures, 1 table The species composition, abundance, vertical distribution, biovolume and carbon content of gelatinous nekton in the Antarctic Polar Frontal Zone are described from a series of RMT25 hauls collected from a series of 200 m depth layers between 0 and 1000 m. In total, 13 spe...
