Abstract

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. Please refer to the data quality statement and supplemental information in the full metadata.

Supplemental Information

To describe the distribution of natural resources that could support future sector development, the Welsh National Marine Plan (WNMP) identifies Resource Areas (RAs) for certain sectors. These are broad areas that describe the distribution of a particular resource that has the potential to be used or is used by certain marine sectors (eg. aggregates, aquaculture or marine energy). RAs have been identified by a process of evidence collection and interpretation. RAs will change as part of marine planning as understanding improves and further evidence becomes available and/or sector technologies develop. In addition to RAs, showing the full spatial extent of natural resources of relevance to a sector, the WNMP allows for the identification of Strategic Resource Areas (SRAs) for certain sectors. SRAs will describe and safeguard (through activation of WNMP policy SAF_02) discrete areas of natural resource with realistic potential to support future sustainable use. The identification and safeguarding of SRAs will help ensure the potential resource interests of sectors are taken into account at an early stage by others, facilitating proactive dialogue between sectors and preventing potential sterilisation of a resource.
