Deep-sea benthic crustacean, polychaete, and sipunculid data from the Bering Sea

Samples of Crustacea, Polychaeta and Sipuncula were collected in the Bering Sea and the Northwest Pacific Ocean during the BERING expedition (SO-249) on board of RV Sonne in 2016. Biological samples were collected using a dredge at depths ranging between 330–5070 m at 32 locations and were stored in 70% ethanol. Specimens were morphologically identified to the lowest taxonomic rank possible using a Leica M60 stereomicroscope. The presented data here comprises taxonomic information as well as annotated bathymetric and biogeographic metadata of a total of 78 samples (26 Crustacea, 47 Polychaeta, 4 Sipuncula and 1 Hirudinea). All data was prepared following Darwin Core Biodiversity standards for FAIR data sharing based on OBIS guidelines.
