Organic pollutants in marine sediments

Definition: The dataset shows the content of organic pollutants in marine sediments. Sediment samples for geochemical analyzes are taken primarily from areas with fine-grained sediments both in open marine depositional environments and coastal sea areas. Sample density varies depending on location. There is a greater sample density in fjords and coastal areas, while in open sea areas there is a lower sample density. The data have been collected on MAREANO cruises in the years 2006-2021, for 2003-2004 they have been collected on monitoring cruises in the Barents Sea and some stations in three pilot areas in the Marine base map in the coastal zone in 2020-2021.

Usage

Chemical data are from areas with presumed deposition of sediments and weak ocean currents. Organic pollutants are also deposited here together with organic material and fine-grained sediments, to which they often bind. Many organic compounds are toxic, even in low concentrations, while at the same time they tend to bioaccumulate, that is to say that the concentration in an organism can increase in relation to the concentration in the environment. In this way, an abnormally high content of organic pollutants in the marine environment can have a harmful effect on marine biota and people who eat seafood.

Explanation of assessment of FAIR principles:

There have made various tests to evaluate datasets in relation to the FAIR criteria. These are our interpretations, which then assess the criteria in relation to standards and protocols used for spatial data in Norway and Europe. For more information on which calculations we use for each indicator, look at the details of FAIR assessments for each specific dataset.

FAIR-status: 100%
