Horn corals

Definition: The dataset shows occurrences of horn corals (soft-bottom and hard-bottom coral forests) observed on the MAREANO surveys. The most common species of horn corals that form soft bottom coral forests are Isidella lofotensis and Radicipes gracilis. The most common species of horn corals that form hard bottom coral forests are Paragorgia arborea, Primnoa resedaeformis, Paramuricea placomus and Swiftia (in the Mareano area Swiftia has not been identified with certainty). The dataset is shown as point data of single occurrences of horn corals based on visual observations along the video transect where MAREANO has collected video material.

Usage

The dataset shows the habitats of horn corals that should be taken into account in connection with the planning of activities that may lead to disturbance of the habitats of horn corals. The data set can be used as a tool for marine spatial and environmental planning, vulnerability analyses, habitat mapping and in connection with installations on the seabed and activities that may have an impact on the seabed. Furthermore, the data set can be used as a basis for decision-making when assessing new farming licences, discharges into the sea, depositions, development of petroleum-related installations, and regulation of fishing activity.

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: 98%
