{"projectrec":{"ProID":3888,"StandardTitle":"Monitoring the effects of disposal of dredged material on the benthos of the Belgian coast","OrigTitle":"Monitoring van de effecten van het lossen van baggerspecie op het bodemleven voor de Vlaamse kust","Acronym":"BAGGER","AbstractEnglish":null,"AbstractOtherLang":"Binnen deze opdracht wordt nagegaan in welke mate het lossen van baggerspecie een invloed heeft op het ecosysteem op en rond de vijf huidige loswallen, door een vergelijking met enkele referentiezones. Halfjaarlijks worden kwantitatieve en kwalitatieve analyses uitgevoerd op het sediment en het bodemleven, teneinde veranderingen of trends te kunnen waarnemen.\r\n\r\nDe meest gebruikte parameters daarvoor zijn tot op heden nog steeds (1) densiteit (aantal individuen per oppervlakte-eenheid), (2) diversiteit (gebaseerd op het aantal soorten en het aandeel van elke soort in de totale densiteit) en (3) biomassa (gewicht per oppervlakte-eenheid) van het benthos.\r\n\r\nDe diversiteit van het benthos is een belangrijke graadmeter voor de kwaliteit van het Noordzee – ecosysteem. Daarnaast is ook de totale densiteit een goede weergave van de ecologische toestand van een gebied. Een hoge diversiteit alleen is namelijk niet voldoende om van een rijk en gezond gebied te spreken. In het bijzonder geeft de biomassa een idee van de omvang van de voedselvoorraad voor hogere organismen in het voedselweb en kan deze parameter gebruikt worden voor het berekenen van energiefluxen.\r\n\r\nAls indicator wordt onderzocht wat de variaties op korte en lange termijn zijn in deze drie aan elkaar gerelateerde parameters, en dit in relatie tot enkele omgevingsvariabelen, zoals bodemsamenstelling en temperatuur.\r\n\r\nDe chemie (PCB's, PAK's, zware metalen), de biochemie (EROD, bio-accumulatie) en de pathologie (visziekten) worden gelijklopend onderzocht door de Groep Chemisch Milieuonderzoek (interne link naar de groep chemie en de sectie milieumonitoring).\r\n\r\nDe resultaten van deze continue monitoringstudie worden tweejaarlijks gerapporteerd aan de afdeling Maritieme Toegang van het Departement Mobiliteit en Openbare Werken (MOW, het voormalige AWZ). Tevens worden de onderzoeksresultaten van ILVO-Visserij tweejaarlijks gebundeld met deze van BMM, MOW-aMT, MDK-afdeling Kust en CODA in een syntheserapport.\r\n\r\nDe rapporten worden gebruikt door MOW - afdeling Maritieme Toegang bij de beoordeling van de aanvraag van nieuwe baggerstortvergunningen","DateLastModified":{"date":"2024-05-06 10:25:46.257000","timezone_type":1,"timezone":"+00:00"},"ParentProID":null,"BeginYear":1979,"EndYear":null,"BMonth":null,"EMonth":null,"BeginMonth":null,"EndMonth":null,"OrigTitleLangCode":null,"OrigTitleLangID":null,"OrigTitleLangNL":null,"OrigTitleLang":null,"OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":"In Progress","ProgressNL":"Gestart","PublicFlag":1,"CheckedFlag":0,"ND":"2011-04-15","UD":"2011-04-15","DMPFlag":0,"Budget":null,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":null,"ProPartID":12685,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Flemish Government;
