{"projectrec":{"ProID":4709,"StandardTitle":"Study and modelling of DMSP production and its conversion into DMS by North Sea specific phytoplankton","OrigTitle":null,"Acronym":null,"AbstractEnglish":"Dimethylsulphide (DMS) is a climatic gas affecting the global climate through the production of atmospheric aerosols. The ocean is the main natural source as dimethylsulphoniopropionate (DMSP), the DMS precursor, is mainly synthesized by phytoplankton and macroalgae. This project aims to improve the knowledge and modelling of dimethylsulphide production and its emission to the atmosphere in the coastal North Sea. The research strategy combines 3 approaches: laboratory-controlled experimentation with monospecies phytoplankton cultures, field measurements, mechanistic modelling. The DMSP cellular concentrations of key phytoplankton species isolated from the North Sea are measured by gas chromatography. These data will be synthesised and integrated in the mechanistic model MIRO-DMS. Thereafter, this model will be applied to the Southern Bight of the North Sea, and DMS(P) and phytoplankton simulations will be compared with field measurements obtained along a seasonal cycle. Once validated, the model will be analyzed for assessing biotic (phytoplankton diversity) and abiotic (temperature, light, salinity, nutrients, wind speed) controls of DMS production and its emission to the atmosphere.","AbstractOtherLang":"Dimethylsulfide (DMS) is een klimaatgas dat een invloed heeft op het wereldklimaat door de productie van atmosferische aerosol. De oceanen vormen de belangrijkste natuurlijke bron van DMS omdat dimethylsulfoniopropionaat (DMSP), de precursor van DMS, hoofdzakelijk door fytoplankton en macroalgen wordt aangemaakt. Dit project beoogt de verbetering van de kennis en de modellering van de productie van DMS en de emissie ervan in de atmosfeer ter hoogte van de Noordzeekustzone. De onderzoeksstrategie combineert drie benaderingen: gecontroleerde laboratoriumproeven met eensoortige fytoplanktongewassen, veldmetingen en mechanistische modellering. De DMSP-celconcentraties van belangrijke fytoplanktonsoorten geïsoleerd uit de Noordzee worden bepaald door gaschromatografie. Deze gegevens zullen in het mechanistische model MIRO-DMS worden gesynthetiseerd en geïntegreerd. Vervolgens zal het model op de zuidelijke bocht van de Noordzee worden toegepast en zullen modelsimulaties van DMS(P) en fytoplankton worden vergeleken met veldmetingen tijdens een seizoenscyclus. Zodra het model is gevalideerd, kan het worden toegepast om biotische factoren (diversiteit van fytoplankton) en abiotische factoren (temperatuur, licht, saliniteit, voedingsstoffen, windsnelheid) met betrekking tot de productie van DMS en de emissie ervan in de atmosfeer te beoordelen.","DateLastModified":{"date":"2024-05-06 10:25:46.257000","timezone_type":1,"timezone":"+00:00"},"ParentProID":null,"BeginYear":null,"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":null,"ProgressNL":null,"PublicFlag":1,"CheckedFlag":0,"ND":"2017-02-08","UD":"2017-02-08","DMPFlag":0,"Budget":null,"BudgetCurrency":"EUR"},"parent":null,"persons":null,"projects":null,"events":null,"datasets":null,"institutes":[{"instituterec":{"Acronym":"FNRS","ProPartID":16090,"PublicFlag":1,"OrigNameLangCode":null,"OrigNameLangID":null,"FullOrigName":null,"Line1":"5 rue d'Egmont","Line2":"1000 Bruxelles","Line3":null,"Line4":null,"InsID":517,"FullStandardName":"Fonds National de la Recherche Scientifique","Role":"Sponsor","RoleID":3,"EncAddress":"5 rue d'Egmont, 1000 Bruxelles, Belgium"},"parent":null,"institutes":null,"references":null,"conferences":null,"datasets":null,"persons":[],"pastpers":null,"subpers":null,"projects":null,"urls":null,"pictures":null,"published":null,"affrefs":null,"collections":null,"thesterms":null,"taxterms":null,"geoterms":null,"thestermsFRIS":null,"nXtins":null,"previns":null,"spcols":null,"resmessage":"no id specified","complete":0,"participantrec":null,"peerrevs":null,"urlmaps":null}],"refs":null,"urls":null,"thesterms":null,"taxterms":null,"geoterms":null,"funderids":null,"othtermsFRIS":null,"pictures":[],"spcols":null,"resmessage":"","complete":1}
