Na deze periode neemt het doorzicht op alle locaties af. Deze afname is het meest uitgesproken in het westen (van 10 - 4 dm) en in iets mindere mate ook in het midden (van 7 - 4). De secchiwaarden in 2001 zijn stabiel voor midden en oost, terwijl in west een stijging is waar te nemen in doorzicht. Omdat de secchi-waarde een belangrijke factor is in de berekeningswijze van de primaire productie, dient er rekening mee gehouden te worden dat primaire productie synchroon zal lopen met de secchi waarden.","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":null,"UDate":"2010-07-19","CDate":"2010-01-27","CurrencyDate":null,"RevisionDate":null,"DateLastModified":{"date":"2026-05-14 01:44:00.153333","timezone_type":1,"timezone":"+02:00"},"CheckedFlag":1,"PublicFlag":1,"VlizCoreFlag":1,"MarineFlag":0,"FreshFlag":0,"BrackishFlag":1,"TerrestrialFlag":0,"StatusID":1,"DasType":"Static graphs","DasTypeID":18,"DasOrigin":null,"Progress":null,"AccessConstraint":null,"AccConstrEN":null,"AccConstrDisplay":null,"License":null,"AccConstrDescription":null,"Lineage":null,"AccConID":null},"dois":null,"spcols":[{"SpColID":27,"SpName":"ScheldeMonitor"}],"keywords":[{"ThesaurusTerm":"ANE, Netherlands, Westerschelde","ThesTypID":34,"ThesType":"ASFA Geoterms","Code":null,"Description":null,"OrigThesTerm":"ANE, Netherlands, Westerschelde","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Annual","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":null,"Description":null,"OrigThesTerm":"Annual","DutchTerm":"Jaarlijks","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Average","ThesTypID":3,"ThesType":"Transportation Research Thesaurus","Code":"Usygb","Description":null,"OrigThesTerm":"Average","DutchTerm":null,"URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Water transparency","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_0861ccd4","Description":null,"OrigThesTerm":"Water transparency","DutchTerm":null,"URI":"http://aims.fao.org/aos/agrovoc/c_0861ccd4","DasKeywordDescr":null}],"parents":null,"children":null,"othrel":null,"othrelrev":null,"ownerships":[{"OrderNr":1,"Surname":null,"Firstname":null,"Initials":null,"PerPublicFlag":null,"AdrID":null,"Email":null,"InsPublicFlag":1,"Acronym":"RIKZ","OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"National Institute for Coastal and Marine Management","InsOwnerCNT":1,"PersID":null,"InsID":5277,"FullInstitute":"Rijksinstituut voor Kust en Zee","RoleID":null,"Role":null,"OrigName":"National Institute for Coastal and Marine Management","StandardName":"Rijksinstituut voor Kust en Zee","FullAcronym":"RIKZ","ORC":null,"ROR":null}],"taxterms":null,"frameworks":null,"otherterms":null,"temporal":[{"DasDateID":1976,"StartYear":1978,"EndYear":2001,"StartDay":null,"EndDay":null,"StartDate":"1978-01-01","EndDate":"2001-01-01","DasDate":null,"Resolution":"Not relevant","ResolutionNL":"Niet relevant","Notes":null,"StartMonth0":null,"StartMonth":null,"StartMonthNL":null,"EndMonth0":null,"EndMonth":null,"EndMonthNL":null,"Progress":null,"ProgressNL":null}],"geographical":[{"GeoTerm":"Westerschelde","DasGeoID":4594,"DasGeoTerm":"Western Scheldt","DasID":2260,"GeotID":385,"X":null,"Y":null,"MaxX":null,"MaxY":null,"StationName":null,"Precision":null,"CoordSystID":null,"GeoDatumID":null,"OrigCoordMinX":null,"OrigCoordMinY":null,"OrigCoordMaxX":null,"OrigCoordMaxY":null,"OrderNr":null,"Projection":null,"GeoDatum":null,"GeoObjectID":4752,"OrigGeoTerm":"Westerschelde","DutchTerm":"Westerschelde"}],"meastypes":[{"MethID":null,"DasMeasTypID":7262,"DasMeasType":null,"Matrix":"Water","MatrixNL":"Water","Parameter":"Secchi depth","ParameterNL":"Secchi diepte","Description":"CEME2","Unit":"dm","Methodology":null,"Protocol":null,"QualityControl":null,"Precision":null,"Detectionlimit":null,"Instrument":null,"InstrumentUrl":null,"MethFull":"","ParaCategoryTitle":null,"ParaCatCode":null}],"dasthemes":[{"DasThemeID":1,"DasTheme":"Coastal studies (e.g. shores, estuaries)","DasTheme0":"Coastal studies (e.g. shores, estuaries)","DutchTerm":"Kustonderzoek (bv. stranden, estuaria)"},{"DasThemeID":7,"DasTheme":"Physical","DasTheme0":"Physical","DutchTerm":"Fysisch"},{"DasThemeID":14,"DasTheme":"Physical > Optical measurements","DasTheme0":"Optical measurements","DutchTerm":"Optische metingen"}],"projects":null,"refs":[{"0":111287,"BRefID":111287,"1":"Describing this dataset","Relation":"Describing this dataset","2":3,"RelationID":3,"3":"<b>Lievaart, M.; Stikvoort, E.</b> (2002).
