{"projectrec":{"ProID":1558,"StandardTitle":"Mud: origin, characterization and human activities","OrigTitle":"Slib: oorsprong, karakterisatie en menselijke activiteiten","Acronym":"MOCHA","AbstractEnglish":"<ul><li>Context\r\n\r\nThe MOCHA (Mud Origin, Characterisation and Human Activities) project is part of the research on “Global Change, Ecosystems and Biodiversity” of the Second Scientific Support Plan for a Sustainable Development Policy (SPSD II) with a priority towards “Evaluation of new methodologies and technologies for studies of sediment transport” as well as “Definition of a zero-point reference framework for the marine ecosystem in the North Sea”. \r\n\r\n\r\n<li>Project Description\r\n\r\n<ul><li>Objectives\r\n\r\nThe MOCHA project is focusing on the cohesive sediment transport system occurring on the Belgian continental shelf (BCS). The presence of mud fields and high turbidity in such an energetic environment has been the subject of various studies, the origin of the mud in the area remains however still controversial. The project aims therefore at presenting evaluation tools and strategies in order to study the different sources of mud. Mud is transported by natural processes, but also human activities (dregding and dumping) have an influence, the project is therefore structured around two entities:\r\n\r\n1. Investigating the contribution of the different possible sources of mud by collecting and critically analysing existing data, by carrying out sediment transport measurements and by analyzing sediment strength, erosion behaviour, clay mineral associations, microfossils, geochemical and geological characteristics. \r\n2. Influence of human activities is investigated by determining how dredging and dumping operations and harbour constructions have changed the cohesive sediment transport system. \r\n\r\nAccurate knowledge of the cohesive sediment distribution and transport system and the different sources is especially important because of its effect on economy (dredging and dumping), environment and for setting up a framework of sustainable management of the North Sea. The project will supply information that is part of the general and permanent duties of monitoring and evaluation of the effects of all human activities on the marine ecosystem to which Belgium is committed following the OSPAR-convention (1992). The construction and extension of the Zeebrugge harbour and its connections to the open sea have created these efficient sedimentation places and have thus changed the natural system. Harbour extensions, deepening of navigation channels and other large scale projects (windmill farms) will continue in the future and thus the choice of efficient dumping sites with a low environmental impact is an essential part of sustainable management. It needs also emphasis that the second goal – the determination of the human impact – will lead to the definition of the zero-point reference framework of the fine grained sediment system, a situation of strongly reduced human influence. Knowledge of this reference framework is needed for the the North Sea “Quality Status Report” an objective of the OSPAR “Joint Assessment and Monitoring Programme”. \r\n\r\n\r\n<li>Methodology \r\n\r\nThe project relies on the expertise of researchers with different backgrounds (geology, mineralogy, sedimentology, engineering, numerical modelling) to collect, measure and analyse all relevant data. It is important to underline that the project aims at understanding the transport system on a regional, i.e. Belgian scale. In these the MOCHA project is coupled with and can rely on the ongoing SPSD II - MAREBASSE project, which is focussing on specific local areas.","AbstractOtherLang":"<ul><li>Context\r\n\r\nHet MOCHA project maakt deel uit van het onderzoek naar “Global Change, Ecosystemen en Biodiversiteit” van het Tweede Plan ter wetenschappelijke ondersteuning van een beleid gericht op duurzame ontwikkeling (PODO 2). Het project richt zijn aandacht op de “Evaluatie van nieuwe methodologieën en technologieën voor de studie van sedimenttransport” en op de “Definitie van een nulpunt referentiekader voor het mariene ecosysteem in de Noordzee”. \r\n\r\n\r\n<li>Beschrijving van het Project\r\n\r\n<ul><li>Doelstellingen\r\n\r\nHet MOCHA project richt zich op het cohesieve sedimenttransportsysteem op het Belgische Continentale Plat (BCP). De aanwezigheid van slibvelden en hoge turbiditeit is reeds het onderwerp geweest van verschillende studies. De oorsprong van het slib blijft echter onderwerp van discussie. Slib wordt getransporteerd door natuurlijke processen, maar ook menselijke activiteiten (bagger- en stortoperaties) hebben een invloed. Het project is daarom gestructureerd rond twee doelstellingen:\r\n\r\n1. Onderzoek van de bijdrage van de verschillende mogelijke slibbronnen door verzameling en kritische analyse van bestaande gegevens, door het uitvoeren van slibtransportmetingen en door de sedimentsterkte, het erosiegedrag, de kleimineralogie, de microfossielen, de geochemische en geologische karakteristieken te analyseren. \r\n2. De invloed van menselijke activiteiten wordt onderzocht door na te gaan hoe bagger- en stortoperaties en de bouw van havenconstructies het cohesieve sedimenttransportsysteem hebben veranderd. \r\n\r\nEen nauwkeurige kennis van de verspreiding, van het transportsysteem en van de verschillende bronnen van cohesieve sedimenten is van groot belang voor de economie (bagger- en stortactiviteiten), het milieu en voor het opzetten van een referentiekader voor een duurzaam beheer van de Noordzee. Het project zal informatie verschaffen die nodig is om de algemene en permanente verplichtingen uit te voeren van monitoring en evaluatie van de effecten van menselijke activiteiten op het mariene ecosysteem, waartoe België zich toe geëngageerd heeft via de OSPAR Conventie (1992). De constructie en uitbreiding van de haven van Zeebrugge en van de vaarroutes hebben efficiënte sedimentatieplaatsen gecreëerd en hebben dus het natuurlijke systeem veranderd. Uitbreidingen van havens, verdieping van vaargeulen en andere grootschalige projecten (windmolenparken), zullen doorgaan in de toekomst. De keuze van efficiënte stortplaatsen met een kleine impact op het milieu is een essentieel deel van het duurzaam beheer. De tweede doelstelling - de bepaling van de menselijke impact - zal leiden tot de definitie van een nulpunt referentiekader voor het slibsysteem, een situatie met sterk gereduceerde menselijke invloed. Kennis van dit referentiekader is nodig voor de publicatie van het “North Sea Quality Status Report”, een objectief van het OSPAR “Joint Assessment and Monitoring Programme”. \r\n\r\n\r\n<li>Methodologie\r\n\r\nHet project baseert zich op de expertise van onderzoekers met een verschillende achtergrond om de relevante gegevens te verzamelen, de metingen uit te voeren en de gegevens te analyseren. Het is belangrijk te onderstrepen dat het project het transportsysteem op een regionale schaal, i.e. de Belgische schaal, tot doel heeft. Hiermee is het MOCHA project gekoppeld aan het PODO-II MAREBASSE project, dat zich meer richt op specifieke locaties.","DateLastModified":{"date":"2024-05-06 10:25:46.257000","timezone_type":1,"timezone":"+00:00"},"ParentProID":1075,"BeginYear":2003,"EndYear":2006,"BMonth":12,"EMonth":4,"BeginMonth":"December","EndMonth":"April","OrigTitleLangCode":"nl","OrigTitleLangID":41,"OrigTitleLangNL":"Nederlands","OrigTitleLang":"Dutch","OtherAbstractLangCode":"nl","OtherAbstractLangID":41,"OtherAbstractLang":"Dutch","OtherAbstractLangNL":"Nederlands","Progress":"Completed","ProgressNL":"Afgelopen","PublicFlag":1,"CheckedFlag":1,"ND":"2005-01-26","UD":"2009-12-14","DMPFlag":0,"Budget":174790,"BudgetCurrency":"EUR"},"parent":{"ProID":1075,"Acronym":"SPSD-II","StandardTitle":"Research action SPSD-II: Second scientific support plan for a sustainable development policy"},"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":"KBIN-BMM","ProPartID":6287,"PublicFlag":1,"OrigNameLangCode":"en","OrigNameLangID":15,"FullOrigName":"Royal Belgian Institute of Natural Sciences;
