Dit gebeurt door middel van bestandsopnamen met onderzoeksvaartuigen en eventueel vanuit de lucht (luchtobservaties en fotografie). \r\n\r\n<B>Werkwijze <\/B><br>\r\nHet werkprogramma omvat de volgende onderdelen: \r\n\r\n1. Kartering en inventarisatie van droogvallende mosselbanken in de Waddenzee\r\n2. Inventarisatie van de hoeveelheden kokkels in de Waddenzee, Zeeuwse stromen en \r\n    voordelta (voornamelijk op de droogvallende platen)\r\n3.

De survey sluit aan op een reeks van surveys, uitgevoerd sinds 1995. In de Voordelta gestart in 1993.De survey geeft een beeld van de verspreiding en talrijkheid van de belangrijkste schelpdieren in de kustzone. Daarnaast wordt een beeld verkregen van veranderingen in de samenstelling van schelpdieren in het kustgebied.Het onderzoek in de ondiepere delen van de Voordelta zal worden uitgevoerd met een gecharterd kokkelvaartuig.In het resterende gebied wordt met het RV \u2018Isis\u2019 gevist. Er wordt gemonsterd met een aangepaste zuigkor c.q. met een \u2018bodemschaaf\u2019 (speciaal voor het bemonsteren van schelpdieren ontwikkelde sleepkor). In totaal zijn8 weken vaartijd gepland (6 weken Isis, 2 weken kokkelvaartuig).Voor een effici\u00ebnte verdeling van de zoekinspanning is het onderzoeksgebied verdeeld in een aantal strata:gebieden met een verschillende kans of verwachting op het voorkomen van strandschelpen en kokkels.Het onderzoek werd vorig jaar gefinancierd uit de vrije ruimte van het programma. De schelpdieren survey inde kustzone is dit jaar op verzoek van LNV-Dvis weer opgenomen in het programma.","Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":"Dutch","EmbargoDate":null,"OrigDescrLangNL":"Nederlands","OrigLangCode":"nl","OrigLangCodeExtended":"dut","OrigLangID":41,"DescrCompFlag":0,"DescrTransFlag":0,"Citation":null,"AccessConstraints":"Restrictions available at contact person","UDate":"2008-04-10","CDate":"2007-06-22","CurrencyDate":null,"RevisionDate":null,"DateLastModified":{"date":"2026-04-02 01:39:52.354985","timezone_type":1,"timezone":"+02:00"},"CheckedFlag":0,"PublicFlag":1,"VlizCoreFlag":1,"MarineFlag":1,"FreshFlag":0,"BrackishFlag":1,"TerrestrialFlag":0,"StatusID":1,"DasType":"Data","DasTypeID":1,"DasOrigin":"Monitoring: field survey","Progress":"In Progress","AccessConstraint":"Restricted","AccConstrEN":"Restricted","AccConstrDisplay":null,"License":null,"AccConstrDescription":"The data are withheld from general circulation and disclosure but access may be obtained on a case-by-case basis through negotiation","Lineage":null,"AccConID":9},"dois":null,"spcols":[{"SpColID":27,"SpName":"ScheldeMonitor"}],"keywords":[{"ThesaurusTerm":"ANE, Netherlands, Oosterschelde","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"ANE, Netherlands, Oosterschelde","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"ANE, Netherlands, Westerschelde","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"ANE, Netherlands, Westerschelde","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"ANE, Wadden Sea","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"ANE, Wadden Sea","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Monitoring","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_4911","Description":null,"OrigThesTerm":"Monitoring","DutchTerm":"Monitoring","URI":"http:\/\/aims.fao.org\/aos\/agrovoc\/c_4911","DasKeywordDescr":null}],"parents":null,"children":[{"DasID":563,"Acronym":null,"EngAbstract":"Yearly cockle stock inventory in the Westerschelde estuary, starting from 1992.","License":null,"StandardTitle":"Cockle stocks Westerschelde","doi":null,"vlizDoi":null}],"othrel":null,"othrelrev":null,"ownerships":[{"OrderNr":1,"Surname":null,"Firstname":null,"Initials":null,"PerPublicFlag":null,"AdrID":null,"Email":null,"InsPublicFlag":1,"Acronym":"IMARES","OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":null,"InsOwnerCNT":2,"PersID":null,"InsID":7095,"FullInstitute":"Wageningen University and Research Centre;
