POSEIDON is a multi-year, multi-partner project funded through The Crown Estate OWEC programme and led by Natural England. The series constitutes:\r\n First seasonal (October to December 2022) report outlining results from digital aerial surveys conducted in January 2023 within the Central North Sea under the POSEIDON project and commissioned by Natural England. Surveys were undertaken using APEM\u00e2??s high-resolution camera system to capture digital still imagery of birds and marine megafauna within the Survey Area. The survey was successfully carried out across three days in January 2023 with no safety issues. Due to weather delays, it was not possible to carry out the survey by the end of December 2022. A total of 3,634 observations were recorded during the survey in January 2023, of which 3,835 were observations of birds and 81 observations of marine megafauna.\r\n Second seasonal (January to March 2023) report outlining results from digital aerial surveys conducted in February 2023 within the Central North Sea under the POSEIDON project and commissioned by Natural England. Surveys were undertaken using APEM\u00e2??s high-resolution camera system to capture digital still imagery of birds and marine megafauna within the Survey Area. The survey was successfully carried out across two days in February 2023 with no safety issues. A total of 7,986 observations were recorded during the survey in February 2023, of which 7,795 were observations of birds and 191 observations of marine megafauna. \r\n Third seasonal (April to June 2023) report outlining results from digital aerial surveys conducted in May 2023 within the Central North Sea under the POSEIDON project and commissioned by Natural England. Surveys were undertaken using APEM\u00e2??s high-resolution camera system to capture digital still imagery of birds and marine megafauna within the Survey Area. The survey was successfully carried out across two days in May 2023, the final 2 nm of line 4 were aborted due to safety concerns over low clouds. A total of 6,995 observations were recorded during the survey in May 2023, of which 6,105 were observations of birds and 890 observations of marine megafauna.\r\n Fourth seasonal (July to September 2023) report outlining results from digital aerial surveys conducted in August 2023 within the Central North Sea under the POSEIDON project and commissioned by Natural England. Surveys were undertaken using APEM\u00e2??s high-resolution camera system to capture digital still imagery of birds and marine megafauna within the Survey Area. The survey was successfully carried out across two days in August 2023. A total of 9,315 observations were recorded during the survey in August 2023, of which 8,928 were observations of birds and 387 were observations of marine megafauna.", "includedInDataCatalog": { "@id": "http://portal.medin.org.uk/portal/json-ld/catalog.jsonld" }, "conditionsOfAccess": [ "otherRestrictions: Publicly Available" ], "temporalCoverage": "2023-01-20/2023-08-22", "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/P22/current/32/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P22/current/", "termCode": "32", "name": "Species distribution" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/BRDA/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "BRDA", "name": "Bird counts" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/CEBH/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "CEBH", "name": "Cetacean behaviour" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/CETA/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "CETA", "name": "Cetacean abundance" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/FOCA/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "FOCA", "name": "Seal abundance" }, { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/P02/current/GP088/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/P02/current/", "termCode": "GP088", "name": "Bird behaviour" }, { "@type": "DefinedTerm", "name": "Research" }, { "@type": "DefinedTerm", "name": "Research and Development Activity" } ], "spatialCoverage": [ { "@type": "Place", "geo": { "@type": "GeoShape", "box": "55.5 -1 56.5 3" }, "name": { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/C19/current/1_2/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/C19/current/", "termCode": "1_2", "name": "North Sea" }, "additionalProperty": [ { "@type": "PropertyValue", "propertyID": "http://www.opengis.net/def/crs/OGC/1.3/CRS84", "value": "urn:ogc:def:crs:EPSG:4326" } ] }, { "@type": "Place", "geo": { "@type": "GeoShape", "box": "55 -0.89 55.5 3" }, "name": { "@type": "DefinedTerm", "identifier": "http://vocab.nerc.ac.uk/collection/C19/current/1_2/", "inDefinedTermSet": "http://vocab.nerc.ac.uk/collection/C19/current/", "termCode": "1_2", "name": "North Sea" }, "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": "The Crown Estate", "description": "custodian", "email": "enquiries@thecrownestate.co.uk", "telephone": "+44 020 7851 5000", "address": { "@type": "PostalAddress", "streetAddress": "1 St James's Market", "postalCode": "SW1Y 4AH", "addressLocality": "London" } } ], "producer": [ { "@type": "Organization", "name": "APEM Limited", "description": "originator", "email": "dot@apemltd.co.uk", "address": { "@type": "PostalAddress" } } ], "publisher": [ { "@type": "Organization", "name": "ABP Marine Environmental Research Ltd", "description": "pointOfContact", "email": "enquiries@abpmer.co.uk", "address": { "@type": "PostalAddress" } } ], "creator": [ { "@type": "Organization", "name": "APEM Limited", "description": "originator", "email": "dot@apemltd.co.uk", "address": { "@type": "PostalAddress" } } ], "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.
