The impact of sea ice regime on meiobenthic structure and function north of Svalbard
Eight stations located in the seasonal sea ice zone north of Svalbard were investigated during ‘TRANSSIZ’ cruise within Arctic in Rapid Transition initiative. Nematodes were used as a key group within the meiofauna. Our study provides previously unavailable data on nematode diversity for this Arctic...
