Abstract

The data set contains information on occurrence, counts and weights (per 11.7 diameter core) of benthic macrofauna at one location at 500 m and one location at 1500 m on the continental slope north of Svalbard, sampled in Feb/Mar 2023.

Natural collections description

Collection name: Macrobenthos JC3 (specimens will be archived at the Arctic University Museum of Norway in Tromsø)

Methods

Method step description: In the home lab, samples were sorted to major taxa first under a stereomicroscope (partly at UiT, partly at IOPAN). Subsequently macrofauna taxa were identified to the lowest possible taxonomic level, enumerated and the weight taken. Meiofauna in the samples was identified to phylum level only. Fragments were not enumerated but weighed. Taxonomic identification my be improved for some individuals in the future.
Study extent description: Continental slope to the Nansen Basin north of Svalbard 
Sampling description: Sediment samples for analysis of macrofaunal diversity, abundance and biomass were taken from multiple 11.7 cm diameter cores inserted in 50x50 cm box cores. These cores were first used for sediment community oxygen respiration and then gently sieved completely through 250 µm for macrofaunal community estimates with cold seawater. The remaining biota was then preserved in a 4% buffered formaldehyde-seawater solution that was rose Bengal-stained. This work is part of RF3 of the Nansen Legacy project, cruise JC3, Feb/Mar 2022. Protocol version 10 was used (10.3.9, but smaller sieve size and different contact person).
