It has been tested at the Mar Menor, an oligotrophic coastal lagoon located in the SE of Spain, based on a flight synchronized with sampling of water and substrate. The spectral information was obtained from Daedalus 1268 multispectral scanner which configuration was similar to CZCS. Samples from water and substrate were analysed in the laboratory to quantify environmental parameters. The lagoon has an average depth of 3.5 m and a maximum depth of 6.6 m. Bottoms are mainly covered by dense Caulerpa prolifera-Cymododea nodosa beds. The lagoon surface, which is about 135 km(2), was covered with five aeroplane passages. The proposed approach assumes that the coefficient of water attenuation (K) is not constant throughout the scene and these variations are related to chlorophyll a concentration. A new method to obtain K for each pixel was previously developed."@es ; dct:identifier "e66435c2-adfa-5f29-8617-d6cea36dd537" ; dct:issued "2024-11-05T00:00:00+00:00"^^xsd:dateTime ; dct:language ; dct:license ; dct:modified "2026-06-25T00:00:00+00:00"^^xsd:dateTime ; dct:publisher ; dct:spatial ; dct:title "New approach to chlorophyll a determination in shallow coastal waters by remote sensing"@es ; dct:type ; adms:status ; dcat:contactPoint ; dcat:distribution ; dcat:keyword "diversidad"@es ; dcat:landingPage ; dcat:theme , . a foaf:Agent ; dct:identifier "E05068001" ; dct:type ; foaf:homepage ; foaf:mbox "bzn-datos@miteco.es" ; foaf:name "Inventario Español del Patrimonio Natural y de la Biodiversidad"@es . a dct:Location ; skos:prefLabel "Región de Murcia" ; dcat:bbox "POLYGON ((-2.3400 37.3800, -0.6900 37.3800, -0.6900 38.7600, -2.3400 38.7600, -2.3400 37.3800))"^^gsp:wktLiteral ; dcat:centroid "POINT (-1.5150 38.0700)"^^gsp:wktLiteral ; locn:geometry "POLYGON ((-2.3400 37.3800, -0.6900 37.3800, -0.6900 38.7600, -2.3400 38.7600, -2.3400 37.3800))"^^gsp:wktLiteral . a dct:LinguisticSystem . a dct:LinguisticSystem . a foaf:Document . a dcat:Distribution ; dcatap:applicableLegislation ; dcatap:availability ; dct:accessRights ; dct:format ; dct:issued "1996-01-01T00:00:00+00:00"^^xsd:dateTime ; dct:language ; dct:license ; dct:modified "2026-06-25T00:00:00+00:00"^^xsd:dateTime ; dct:title "Distribución HTML"@es ; cnt:characterEncoding "UTF-8" ; dcat:accessURL ; dcat:mediaType . a vcard:Kind ; vcard:fn "Organismo publicador del Catálogo"@es ; vcard:hasEmail ; vcard:hasURL ; vcard:role . a dct:Standard . a eli:LegalResource . dct:type .
