Broad habitat - Subtidal Rock

What is it:

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.

More Information:

The model was created using raster input layers with a cell size of 0.002dd (roughly 250 meters). 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.

For more information on the modelling process see the EMODnet Seabed Habitats on the ‘Data Sources’ tab.
