Creepy-Crawlies of the Arctic deep sea: Metazoan meiobenthic communities across latitudinal and bathymetric gradients in the western Arctic Ocean

Knowledge on meiofauna in the Arctic Ocean is lacking despite their importance for ecosystem functioning. The Synoptic Arctic Survey aimed to fill such knowledge gaps and thus included meiofaunal sampling. A bathymetric transect (from shelf to central basins) was sampled in the western Arctic Ocean during the HLY2202 expedition. Four sampled transect stations were investigated to answer three key questions: (1) How does the meiofaunal community change along the transect? (2) Which sedimentary parameters drive the meiofaunal community compositions? (3) Has the meiofaunal community at the North Pole changed since 1996, and if so, how? The uppermost three centimeters of sediment were analyzed for metazoan meiofaunal composition (including meiofaunal abundance and nematode biomass) in relation to food proxies (i.e. bacterial …
