Sea-ice meiofauna biodiversity from the Micro-SHIFT cruise May 2025 (cruise number: 2025007006): individual counts, abundance and biomass

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 13 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.

Sampling Methods

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.

Method step description:

1. 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).
