The survey work presented here found no\r\nevidence to suggest that Sabellaria spinulosa reef had built up during that time.\r\nAll of the sites found to support the biotope SS.SBR.PoR.SspiMx previously were\r\nfound to support the same biotope. These were amongst 10 of the 16 sites surveyed\r\nwhich have remained the same as those assigned previously.\r\nOf the seven sites within the turbine area (6, 18, 21, 26, 30, 31 and 47) four have\r\nbeen assigned different biotopes; these are 6, 26, 30 and 47. For sites 6 and 26 the\r\nchange is relatively minor between related biotopes. For sites 30 and 47 the\r\napparent change in sediment from coarse to fine sands is more interesting.\r\nHowever, the same change was also seen at site 7 well outside the windfarm area\r\nand approximately three kilometers east of the main cable route. Hence these\r\nchanges appear to be natural in the habitats prevailing in the area.\r\nSite 10 was the only location found previously for the SS.SCS.ICS.MoeVen biotope\r\nbut is now, again uniquely, SS.SCS.ICS.Glap. These two biotopes are related, with\r\nthe former grading into the latter where the sediment is subject to continual\r\ndisturbance.\r\nOf the 44 video sites analysed, 42 did not register a score for either elevation or\r\npatchiness. Neither of the remaining 2 locations, site 4 and 21, scored for both\r\nelevation and patchiness. Site 4 had a score of \u2018medium\u2019 for patchiness, but the\r\nelevation was less than 1cm illustrating this was a thin crust only and would need to\r\nbe more than twice this measure to register a score. Although not part of the grab\r\nsurvey an extra grab sample was taken at this location and inspected during the\r\nsurvey thus reinforcing the elevation measure here for those pebbles encrusted with\r\nSabellaria spinulosa. Site 21 measured \u2018low\u2019 for elevation, but this assessment was\r\nbased on a single loose pebble with an estimated tube length of 3cm. The grab\r\nsamples at site 21 show the numbers of Sabellaria to be about 200m-2 well below\r\nHendrick and Foster-Smith (2006) requirement of 500m-2 for a \u2018low-grade\u2019 reef score.\r\nFurthermore as the UK Biodiversity Group (1999) notes, crusts may only be seasonal\r\nfeatures, easily broken up by winter storms and then reforming the following spring.\r\nAs such they are ephemeral constructs only, unable to provide stable biogenic\r\nhabitats for associated species and therefore cannot be considered true Sabellaria\r\nspinulosa reefs.\r\nThe cable route video study identified three biotopes that are typical of robust sand\r\nand gravelly sand habitats, primarily supporting Pomatoceros sp.\r\nThese findings are consistent with data results from previous surveys.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "no conditions apply" ], "temporalCoverage": "2009-11-03/2009-12-21", "keywords": [ { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/M04/current/M0403/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/M04/current/", "termCode": "M0403", "name": "Pre-Construction monitoring" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/M03/current/M0309/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/M03/current/", "termCode": "M0309", "name": "Offshore Cable Corridor" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/M03/current/M0316/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/M03/current/", "termCode": "M0316", "name": "Renewable Energy Lease area" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/HBCH/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "HBCH", "name": "Habitat characterisation" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/HBEX/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "HBEX", "name": "Habitat extent" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/FABD/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "FABD", "name": "Fauna abundance per unit area of the bed" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/N010/4/NDGO0001", "name": "Marine Environmental Data and Information Network" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/N01/current/NDGO0001/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/N01/current/", "termCode": "NDGO0001", "name": "Marine Environmental Data and Information Network" } ], "spatialCoverage": { "@type": "Place", "geo": { "@type": "GeoShape", "box": "53.096122217091 1.0742216214591 53.174333255759 1.2244886798664" }, "additionalProperty": [ { "@type": "PropertyValue", "propertyID": "http://www.opengis.net/def/crs/OGC/1.3/CRS84", "value": "urn:ogc:def:crs:EPSG:4326" } ] }, "maintainer": [ { "@type": "Organization", "name": "Scira Offshore Energy Ltd", "description": "custodian", "email": "info@scira.co.uk", "telephone": "0044(0) 203 204 3200", "faxNumber": "N/A", "address": { "@type": "PostalAddress", "streetAddress": "One Kingdom Street, London, W2 6BD, United Kingdom" } } ], "producer": [ { "@type": "Organization", "name": "Scira Offshore Energy Ltd", "description": "originator", "email": "info@scira.co.uk", "telephone": "0044(0) 203 204 3200", "faxNumber": "N/A", "address": { "@type": "PostalAddress", "streetAddress": "One Kingdom Street, London, W2 6BD, United Kingdom" } } ], "publisher": [ { "@type": "Organization", "name": "Scira Offshore Energy Ltd", "description": "pointOfContact", "email": "info@scira.co.uk", "telephone": "0044(0) 203 204 3200", "faxNumber": "N/A", "address": { "@type": "PostalAddress", "streetAddress": "One Kingdom Street, London, W2 6BD, United Kingdom" } } ], "creator": [ { "@type": "Organization", "name": "Scira Offshore Energy Ltd", "description": "originator", "email": "info@scira.co.uk", "telephone": "0044(0) 203 204 3200", "faxNumber": "N/A", "address": { "@type": "PostalAddress", "streetAddress": "One Kingdom Street, London, W2 6BD, United Kingdom" } } ], "sdPublisher": { "@type": "Organization", "url": "https://portal.medin.org.uk/portal/", "name": "Marine Environmental Data and Information Network (MEDIN)", "description": "The MEDIN portal contains information about 19493 marine datasets from over 600 UK organisations.
