Horn corals

The dataset shows occurrences of horn corals (soft bottom and hard bottom coral forests) observed on the MAREANO cruises. 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 is not proven with certainty). The dataset is shown as point data of individual instances with horn corals based on visual observations along video transects where MAREANO has collected video material.
