Macrobenthos of the Nansen and Amundsen Basins from the Nansen Legacy joint cruise JC2-2 in Aug/Sept 2021. Version 1.7. The Nansen Legacy Project. Sampling event dataset https://doi.org/10.15468/twumu2 accessed via GBIF.org on 2024-12-12.Description
The data sets contains information on occurrence, counts and weights (per 11.7 diameter core) of benthic macrofauna at one locations (P8) in the Nansen Basin, one location on the Gakkel Ridge (P9) and two locations (P10, P11) in the Amundsen Basin, sampled in Aug/Sept 2021.Sampling Description
Study Extent
Nansen Basin, Amundsen BasinSampling
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 JC2-2, August/September 2021. Protocol version 9 was used (10.3.9, but smaller sieve size and different contact person).Method steps
- 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.
