Distribution and composition of macrozoobenthic communities along a Victoria-Land transect (Ross Sea, Antarctica), with special emphasis on the peracarid crustacean fauna
The Victoria Land Transect Cruise with the Italian research vessel "Italica", carried out in February 2004, was the first large-scale attempt to obtain benthic samples systematically along a latitudinal transect along the Antarctic Ross Sea shelf. Along the transect, samples were taken in...
