說明

The data was collected during the Micro-SHIFT cruise in May 2025 (cruise number: MS7006) onboard the research vessel RV Kronprins Haakon (cruise report: https://data.npolar.no/dataset/90e39c2b-fd7f-44d7-a58c-866f8dea66de). The expedition was a 20-day drift study. The dataset contains individual countas, abundance and biomass of sea-ice meiofauna (> 20 µm) including metazoans eggs and large protists such as foraminifers and ciliates. Sea-ice meiofauna were identified and counted with a stereo microscopy and results are given as Individuals per liter (cells/L) and Individuals per square meter (Ind/m2). Biomass (μg C Ind.-1 per L and per m2) was only determined for alive individuals according to carbon contents for ice meiofauna taxa based on literature according to Marquardt et al. 2023 and references within in (https://doi.org/10.1016/j.pocean.2023.103128).

取樣方法

Ice cores were taken for the determination of abundance and biomass of sea-ice meiofauna and protists (lowermost 5 cm) every four days during a 20-day drift study. Three ice cores were taken from undeformed level ice areas with a KOVACS ice corer (Mark II coring system, diameter 9 cm) and were cut on the snow-free sea ice, only the 0-5 cm (bottom ice layer) section was collected. All sea-ice core sections were melted in the dark and at 4°C within 24-28 h to and to reduce negative impacts related to osmotic stress 100 ml filtered seawater (< 0.22 µm) was initially added per 1 cm section.
