Descripción
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.
Registros
Los datos en este recurso de registros biológicos han sido publicados como Archivo Darwin Core(DwC-A), el cual es un formato estándar para compartir datos de biodiversidad como un conjunto de una o más tablas de datos. La tabla de datos del core contiene 49 registros.
también existen 1 tablas de datos de extensiones. Un registro en una extensión provee información adicional sobre un registro en el core. El número de registros en cada tabla de datos de la extensión se ilustra a continuación.
Este IPT archiva los datos y, por lo tanto, sirve como repositorio de datos. Los datos y los metadatos del recurso están disponibles para su descarga en la sección descargas. La tabla versiones enumera otras versiones del recurso que se han puesto a disposición del público y permite seguir los cambios realizados en el recurso a lo largo del tiempo.

Métodos de muestreo
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.
| Área de Estudio | 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. |

Descripción de la metodología paso a paso:
- 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.
