Description

This dataset contains data on benthic foraminiferal species collected during one expedition in August 2019 on the Barents Sea continental shelf. Sediment surface samples were taken with a Gemini-corer. The generated datasets presented here comprise occurrence and density (individuals per 10 cm-2) records of benthic foraminifera from eight samples.

Sampling Methods

Duplicate sediment cores were taken from two stations using a Gemini corer (8 cm inner diameter).

Study Extent Sediment sampling was conducted during a single expedition aboard R/V Lance in August 2019, between 76.3 - 76.7 °N and 32-37 °E at approximately 250 m water depth.

Method step description:

  1. The surface sediment (0-1 cm) was washed over a 500 and 63 μm mesh sieve. The rB–stained foraminifera (>63 μm) were wet-picked, identified, and counted under a Nikon SMZ18 stereomicroscope. Individuals were identified to the lowest taxonomic level possible.
