The entire survey covered a total area of approximately 34.5 square kilometres. The survey was commissioned to meet two main objectives: 1) To identify the thickness of sediment units and depth to rockhead; and 2) To identify the positions of possible ferrous debris. In order to meet these requirements the following data were collected:\r\n\u2022 Seismic data to provide information on the sub-surface geology and thickness of\r\nsurficial sediments\r\n\u2022 Bathymetric soundings to determine seabed topographic variations and to reduce\r\nseismic data to datum\r\n\u2022 Magnetometer data to determine the position and size of ferrous objects\r\nThe collection of survey data was undertaken between 3rd February and 5th February 2005\r\nutilising a vessel called \u2018Kirkspray\u2019.\r\nA comprehensive set of data was collected throughout the survey site. The bathymetry data\r\nindicate that the seabed slopes gently from 10m below Chart Datum (CD) in the northwest\r\ncorner, towards the southeast to a maximum depth of 30m below CD.\r\nUnderlying less than 1m of surface sediments are glacial tills, which form a generally uniform\r\nhorizon. This top horizon, thought to be ablation till, has been divided locally into the Upper\r\nSedimentary Unit (USU) and the Lower Sedimentary Unit (LSU). The total thickness of these\r\nunits ranges from 5 to 13m with the greater values found in the north east of the survey area.\r\nThe base of the Sediment Units/top of the underlying chalk is not a distinct horizon due to the\r\nfact that the top of the chalk is heavily weathered. Therefore, a change in the character of the\r\nseismic records rather than a distinct reflector has been mapped and is likely to coincide with\r\nthe weathered zone at the top of the bedrock.\r\nThe magnetometer data indicate that there are several small ferrous objects on the site.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "no conditions apply" ], "temporalCoverage": "2005-02-03/2005-02-05", "keywords": [ { "@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" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P23/current/MD001/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P23/current/", "termCode": "MD001", "name": "Marine Geology" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/M040/1/M0401", "name": "Feasibility" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/M030/1/M0301", "name": "Agreement for Lease Area" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P141/4/GVAR0873", "name": "Tidal Height" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P141/4/GVAR0739", "name": "Sedimentary Structures" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P141/4/GVAR0490", "name": "Magnetic Anomalies" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P231/3/MD005", "name": "Physical Oceanography" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/76/MBAN", "name": "Bathymetry and Elevation" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/S040/79/S04164", "name": "echo sounder" }, { "@type": "DefinedTerm", "identifier": "http://vocab.ndg.nerc.ac.uk/term/P021/76/SRFL", "name": "Seismic reflection" } ], "spatialCoverage": { "@type": "Place", "geo": { "@type": "GeoShape", "box": "53.164480450937 0.44765720155553 53.271317239598 0.52389494189844" }, "additionalProperty": [ { "@type": "PropertyValue", "propertyID": "http://www.opengis.net/def/crs/EPSG/0/27700", "value": "National Grid of Great Britain - urn:ogc:def:crs:EPSG::27700" } ] }, "maintainer": [ { "@type": "Organization", "name": "Centrica Renewable Energy Limited", "description": "custodian", "email": "renewables.documentcontrol@centrica.com", "telephone": "01753 492188", "address": { "@type": "PostalAddress", "streetAddress": "Millstream East 1st Floor, Maidenhead Road", "postalCode": "SL4 5GD", "addressLocality": "Windsor", "addressRegion": "Berkshire", "addressCountry": "United Kingdom" } } ], "producer": [ { "@type": "Organization", "name": "EMU Ltd - Head Office", "description": "originator", "email": "marketing@emulimited.com", "telephone": "01489 860050", "faxNumber": "01489 861051", "address": { "@type": "PostalAddress", "streetAddress": "1 Mill Court, The Sawmills", "postalCode": "SO32 2EJ", "addressLocality": "Southampton", "addressRegion": "Hampshire", "addressCountry": "United Kingdom" } } ], "publisher": [ { "@type": "Organization", "name": "Centrica Renewable Energy Limited", "description": "pointOfContact", "email": "renewables.documentcontrol@centrica.com", "telephone": "01753 492188", "address": { "@type": "PostalAddress", "streetAddress": "Millstream East 1st Floor, Maidenhead Road", "postalCode": "SL4 5GD", "addressLocality": "Windsor", "addressRegion": "Berkshire", "addressCountry": "United Kingdom" } } ], "creator": [ { "@type": "Organization", "name": "EMU Ltd - Head Office", "description": "originator", "email": "marketing@emulimited.com", "telephone": "01489 860050", "faxNumber": "01489 861051", "address": { "@type": "PostalAddress", "streetAddress": "1 Mill Court, The Sawmills", "postalCode": "SO32 2EJ", "addressLocality": "Southampton", "addressRegion": "Hampshire", "addressCountry": "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.
