Descrição

### Study area This dataset is the result of sampling at five stations along a transect in the western Barents Sea. ### Time coverage The samples were collected between 7 January 2024 and 12 January 2024. ### Sampling Five pelagic trawl samples were collected with a Harstad pelagic trawl, which has an effective opening of 80 m2 when towed at ca. 3 knots. The mesh size of the inner liner of the cod end was 10 mm. The pelagic trawl was towed at ca. 3 knots for 20-30 min at the target depth and abundances were standardized by converting to catch per unit effort (expressed in kilograms per cubic meter). ### Sample analysis All organisms were identified to the nearest species or genus onboard. Capelin had a large size distribution, so individuals similar in length were sorted into approximate size classes (small, medium, and large). The total number and weight of each species was recorded. For large catches, subsamples of 20-30 individuals were taken as a representation of the length distributions of the catch. The standard length, height at the anus (up to the nearest 1 mm), and weight (up to the nearest 0.1 g) were measured for all specimens caught and those in the subsample for abundant species. ### Data management While the PolarFront project publishes all its data on Zenodo, biological diversity datasets are also published in the Global Biodiversity Information Facility (GBIF). The data is prepared using the international Darwin Core (DwC) vocabulary (https://dwc.tdwg.org/) and is distributed as DwC text files that follows GBIF's [data quality requirements](https://www.gbif.org/data-quality-requirements-sampling-events) and [best practices for sampling event datasets](https://ipt.gbif.org/manual/en/ipt/latest/best-practices-sampling-event-data). Prior to publishing all data files are validated using GBIF's data validator (https://www.gbif.org/tools/data-validator). Taxonomy is also validated against the [GBIF API](https://techdocs.gbif.org/en/openapi/v1/species) and [World Register of Marine Species](https://www.marinespecies.org).

Registros de Dados

Os dados deste recurso de evento de amostragem foram publicados como um Darwin Core Archive (DwC-A), que é o formato padronizado para compartilhamento de dados de biodiversidade como um conjunto de uma ou mais tabelas de dados. A tabela de dados do núcleo contém 5 registros.

Também existem 1 tabelas de dados de extensão. Um registro de extensão fornece informações adicionais sobre um registro do núcleo. O número de registros em cada tabela de dados de extensão é ilustrado abaixo.

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.
