Analysis of survey records held on the Marine Nature Conservation Review (MNCR) database suggest that fully saline sheltered muddy gravel communities are scarce in their British distribution, with available descriptions lacking detail and comprehensive data. This has been attributed to the habitats being difficult to survey and monitor, due to the large quantities of coarse material which require sampling and subsequent analysis. Similarly, historical data on the distribution of muddy gravel beds appears limited. \r\n\r\nThis data set includes results of sediment coring and sampling undertaken at one site in Porthmadog during intertidal monitoring of the muddy gravel in Pen Llyn a'r Sarnau Special Area of Conservation (SAC).", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "access: The following data is considered OS derived data and is therefore jointly owned by NRW and the Ordnance Survey.
