Recent deep-sea ostracods of the sub-polar North Atlantic Ocean

Abstract

Presented here is an illustrated checklist of benthic marine Ostracoda (Crustacea) recorded from Recent surface sediments of the sub-polar North Atlantic Ocean (SPNA). It presents 142 species (and species groups) belonging to 62 genera from 41 sampling sitescollectedfromthewaterdepthsof144-2749m.Weprovidecensusdatawithscanningelectronmicroscopeimagesofrepresentative specimens of mostspecies, as wellas geographicaland bathymetricaldistribution maps of selected species and genera. Samples fromthe Nordic seas (i.e., Greenland Sea, Norwegian Sea), as well as North Atlantic proper waters (i.e., Irminger Sea, Iceland Sea) are included. The bathymetry covers shelf to continental rise surface sediments from the Irminger Basin, the Iceland Basin, the Iceland Plateau, the Denmark Strait, the Faeroe-Shetland Channel, the Iceland-Faeroe Ridge, the Reykjanes Ridge, and the Faeroe Plateau. The data presented here is an important taxonomic and biogeographical baseline of the SPNA benthic ostracod fauna.
