Description
This dataset was created based on data collected during the scientific cruise in the western part of Svalbard, conducted as part of the AB-202 course at the University Centre in Svalbard. During the cruise, benthic and pelagic trawl samples were taken at four different locations in Isfjorden, Kongsfjorden, a cold seep site, and the marginal ice zone in the northwest of Svalbard. The dataset includes the abundance of all captured fish, as well as the average weight and length for the four species: Atlantic Cod, Polar Cod, Capelin, and Herring.
Data Records
The data in this occurrence 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 49 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.

Sampling Methods
The fish were collected using benthic and pelagic trawls, and the trawls were out for around 10-15 minutes. The fish was sorted and identified. Total weight was measured for each species found, and additionally weight and length were measured for 20 random individuals of the key species: capelin, atlantic herring, atlantic cod and polar cod. If there were fewer than 20 then all of the individuals were measured. The depth for the pelagic trawl was decided based on data from an echo sounder. It was chosen where the highest biomass reading in the water column was found. There was not done a pelagic trawl at the MIZ location due to ice concerns and time constraints.
| Study Extent | The sampling stations were: IsK - Isfjorden, KB3 - Kongsfjorden, SEEP - outside Magdalenafjorden and MIZ - in the marginal ice zone northwest of Spitsbergen. IsK and KB3 are a part of a longterm monitoring program and are sampled every year on this expedition. The SEEP station has not been sampled before and is a methane seep location. The MIZ location is located in the marginal ice zone, and this year it was at about 80* north. |

Method step description:
- The benthic trawl was done and the fish was sorted and identified by students. Total weight for each species was measured, and the key species were subsampled. The pelagic trawl depth was decided based on echo sounder data. The fish was sorted and identified by students. Total weight for each species was measured, and the key species were subsampled.
