Broad Habitat - Subtidal Rock (EUSeaMap2 - EUNIS) - July 2019
This map layer has been supplied directly by Marine Scotland National Marine Plan interactive. You can obtain additional information about the layer on this page
Output of the 2019 EUSeaMap broad-scale predictive model, produced by EMODnet Seabed Habitats. The extent of the mapped area includes the Mediterranean Sea, Black Sea, Baltic Sea, and areas of the North Eastern Atlantic extending from the Canary Islands in the south to the Barents Sea in the north.
The map was produced using a "top-down" modelling approach using classified habitat descriptors to determine a final output habitat. Habitat descriptors (excepting Substrate) are calculated using underlying physical data and thresholds derived from statistical analyses or expert judgement on known conditions. The model is produced using R and Arc Model Builder (10.1).
The model was created using raster input layers with a cell size of 0.00104dd (roughly 100 metres). The model includes the sublittoral zone only; due to the high variability of the littoral zone, a lack of detailed substrate data and the resolution of the model, it is difficult to predict littoral habitats at this scale.
This layer depicts the Subtidal Rock Habitats derived from the EUSeaMap2. Subtidal rock habitats comprise bedrock, boulders and cobbles occurring below low water mark. The communities found here are strongly affected by the availability of light; shallow areas are typically dominated by seaweeds and in deeper areas below the photic zone (about 50m) communities comprise exclusively animals. Other factors influence the composition of communities including wave action, tidal stream strength and salinity.
