The tidal range RA shows the spatial distribution of natural resources that, in terms of technical feasibility (water depth and tidal range) only, have potential to support sector activity. It does not in any way indicate any appropriateness of potential sector activity within these areas. The tidal range RA is based on a maximum depth of 25 m below chart datum and a mean spring tidal range of greater than 6 m. The tidal range RA was defined using tidal range data from the Atlas of UK Marine Renewable Energy Resources (ABPmer, 2008) and bathymetry data from the OceanWise Marine Themes Digital Elevation Model (DEM) (Oceanwise, 2014). The RA was clipped/extended (as appropriate) to meet the mean high water mark (as defined by the May 2022 Ordnance Survey Boundary-line dataset).

Derivation of RAs

Resource Areas (RAs) are broad areas that describe for some sectors the distribution of a particular resource that has the potential to be used or is used.

RA derivation does not include environmental factors, the assessment of which must be undertaken before issuing a licence; at which point more detail is known on any proposal.
