Macrofauna under sea ice and in the open surface layer of the Lazarev Sea, Southern Ocean
A new fishing gear was used to sample the macrozooplankton and micronekton community in the surface layer (0-2 m) under ice and in open water, the Surface and Under Ice Trawl (SUIT). In total, 57 quantitative hauls were conducted in the Lazarev Sea (Southern Ocean) during 3 different seasons (autumn...

The response of the community composition to the presence of sea ice was influenced by species that were significantly more abundant in open water than under ice (Cyllopus lucasii, Hyperiella dilatata), only seasonally abundant under ice (Clione antarctica), or significantly associated with sea ice (Eusirus laticarpus).
