Open data via BarentsWatch

BarentsWatch collects and develops public information from many of our partners and other suppliers for use in our services and web pages. Most of the data content you find in our systems is available for free, directly from our partners or via BarentsWatch. Here, we have made a summary.

API updates:

BarentsWatch offer self-help for registration of API:

  1. Log into "My page" You might need to use "REGISTRER AS A NEW USER".
  2. When logged in, see section "For developers" and register "A NEW CLIENT" from "My clients". For more info please see "API access". NB! We hope you take the time to fill in  "Purpose (optional)" under client registration since this will help our development.

NB! If you encounter client authentication problems please check:

Our APIs and map services are primarily made in connection with the requirements we have in our own presentations and are continuously developed. Users who have other requirements and suggestions for how to design these requirements, are requested to contact us. Remember to say something about who you are, what you want, and the purpose of your usage of the data (why), so that we can quickly understand your requirements.

If you are an developer and/or wants to be updated of our data and changes in API you should subscribe to E-mail notifications on API changes ( - «For developers» - «API access»), and check our blog for updates (


Map Services

  • Our WMS and WFS services are available at

  • In the cases where BarentsWatch has carried out a processing of the data that makes the data different from similar services from the data owners, the processing is documented on They are listed under Kystverket – the Coastal Administration – which is the hosting agency for Barentswatch.

What data are available?


Here, the user can view or download data for chartplotters that are relevant for fishing.

  • All data sets for download to relevant formats are available through the API and the WFS service

  • The data we use directly from others can also be displayed as WMS via BarentsWatch, but we recommend using the services directly from data owners for these services. It is only iskant from the Meteorological Institute (iceedge) and anonymous fishing facilities (fishingfacility) that are not already available from data owners such as WMS. There are two WMS layers for each dataset – one containing all data versions we have received and one containing only the latest version.
  • WMS service with time functionality based on anonymous tool data in FiskInfo which forms the basis for Fiskeriaktivitet (Fishing Activity) ( activity). BarentsWatch uses the version with WMS Time, but for external use, we have also created our own layers for each tool category for remote use without time functionality as well as an unfiltered WFS version.
  • Detailed information about ownership of the individual tools is not openly available, but users with access can download this information through the API. Developers who provide solutions for fishermen and want access during a development period can contact BarentsWatch.

Fish Health

Fish Health displays information for each week at the location level (fish farms) regarding salmon lice, fish diseases and data on permits, ownership, etc. from the aquaculture register. The aggregation and history made in BarentsWatch is not available from the data owners themselves and dates back to 2012 for most data.

As a general rule, all data displayed in can also be accessed through API endpoint. Please see API-documentation.

Please use the feedback button and let us know if you have any requirements and wishes for other map services.

Sustainability in aquaculture

The aim of the project is to make facts on environmental, economic and social sustainability in Norwegian aquaculture more accessible by collating and compiling information on one website to show status and trends within the selected themes.

The service presents data indicators for impact on the environment, the economy in the industry and what kind of societal impacts it provides.

As a rule, all data displayed can also be accessed through API endpoint. Please see API-documentation.

Please use the feedback button and let us know if you have any requirements and wishes.

Wave Forecast

The Wave Forecast service displays the reported wave height for given stretches along the Norwegian coast 60 hours ahead of time. It also provides indications of the wave situation outside the stretches of the same areas. The data combines general wave hazard warnings from the Meteorological Institute with base conditions and other variables to provide more accurate alerts in the relevant areas. In this service, we also combine some other services from the Meteorological Institute and the Norwegian Mapping Authority that are not part of the BarentsWatch API/WMS.

The basis for the BarentsWatch display is a combination of WMS (with Time), WFS and API – this is further described in the API documentation. The data we have are:

  • Warning for sea lanes / stretches
    • Geometry for the stretches (Please note! These are not the Coastal Administration's official sea lanes)
    • Significant and maximum wave height in increments of 0.1 nautical miles
    • "Waypoints" with information on points in the stretches where the direction and wave period are included
    • Crossing waves where it overlaps with the stretches
  • Points outside the lanes
    • Corresponding with the information above
  • Contour lines with alerts for areas
    • Geometry within the warning notification areas that displays lines for the wave height in areas
  • Crossing waves
    • Displays areas where crossing waves can be expected


The Saltstraumen Current Warning Service shows the time when the sea current turns and speed (knots) in and out of Saltstraumen in the coming days.

  • Max speed out
  • Max speed in
  • Rectilinear current (Strømsnu)
