## Methods ### Study area This dataset is the result of a sampling program in Isfjorden on the west coast of Spitsbergen, Svalbard. ### Time coverage The sampling was conducted in 2016 and 2017, with one sampling per season; summer and autumn in 2016 and winter and spring in 2017. ### Sampling 50 sea water samples were collected at two stations named "n1" and "s2". On each sampling date three sampling protocols were used: - a fine net deployed horizontally by a diver (100 µm mesh) - a specialized water pump (hoover/vacuum, 100 µm) deployed at a certain depth - vertical plankton net tows (WP2-net, 65 µm). Both the diver's net and vacuum pump sampled from 6 and 12 meters depth at each station, while the WP2-net sampled from 50 to 0 meters and from 12 to 0 meters depth. For station "s2", the sampling at 6 meters with a diver's net and vacuum pump was carried out in the autumn of 2017 and not together with the other sampling that occurred in the autumn of 2016. ## Taxonomy The dataset was analysed using image analysis software (Ecotaxa) with subsequent expert validation. ## Data ## This dataset is built using a [fully automated processing pipeline](https://github.com/akvaplan-niva/gbif-no-darwin-core/blob/main/bin/ecotaxa-pipeline), using the [ecotaxa-occurrences](https://github.com/akvaplan-niva/ecotaxa-darwin-core#ecotaxa-occurrences) ## Processing https://doi.org/10.5281/zenodo.4700253 This dataset contains two Darwin Core distributions - dwc-ndjson: Newline separated JSON (NDJSON) - dwc-a: Darwin Core archive (TSV/XML) command line tool.

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 50 records.
1 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.
