說明

This dataset contains data on benthic foraminiferal species collected during five expeditions between 2018 and 2022 on the continental margin of the northern Barents Sea. Sediment surface samples were taken with a box corer, covering a water depth range of 186 to 3604 m. The generated datasets presented here comprise occurrence and density (individuals per 10 cm-2) records of benthic foraminifera from 61 samples with seasonal resolution.

取樣方法

Three box cores were deployed at eight sites on R/V Kronprins Haakon, each using a short sediment core (5.5 cm diameter) to subsample benthic foraminifera. All surface sediment samples (0-1 cm) were preserved onboard in a 70% ethanol solution stained with 2 g L-1 rose Bengal.

研究範圍 Sediment sampling was performed during five expeditions onboard R/V Kronprins Haakon - August 2019 (Q3), December 2019 (Q4), March 2021 (Q1), and May 2021 (Q2), and February/March 2022 (JC3) between 75-83 °N and 24-34 °E.

方法步驟描述:

  1. The surface sediment (0-1 cm) was washed over a 500 and 63 μm mesh sieve. The 63-500 μm fraction was split using a wet splitter and further subdivided into two fractions: 63-125 μm and 125-500 μm. 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.
