Many organisms release DNA molecules in the marine environment through the excretion of faeces, mucus, gametes or the release of scales and skin cells. This eDNA can be collected in a non-destructive way just by simply sampling and filtering water. However, the application of eDNA sampling as monitoring tool in highly dynamic and relatively shallow systems such as the North Sea is still in its infancy. Our own preliminary results in the North Sea are promising and show that spatial differences in diversity can be picked up with eDNA and that local eDNA concentrations correlate well with abundances of target species in the locations. The benefit of eDNA sampling lays in the zero impact on marine life when only water is collected. Moreover, the eDNA method offers long-term benefits, since it has the potential for automatic and autonomous sample collection through the use of robotics like AUVs.

Monitoring for ecosystem health assessments is currently based on morphological species identification, which is time-consuming, labor-intensive and skills reliant. DNA-based tools promise cheaper, faster and more accurate methods, yet, different approaches between countries are used which hamper standard routine application. The Interreg NSR project GEANS, therefore aims to:\r\n\r\n1. Develop joint time- and cost-reducing genetic monitoring tools that feed into existing indicators to assess North Sea ecosystem health\r\n2. Implement standardized genetic tools and SOPs in routine biological assessments\r\n3. Develop a framework to apply and implement DNA-based tools in policy and transnational management of the North Sea Region.","License":null,"StandardTitle":"Genetic tools for Ecosystem health Assessment in the North Sea region","doi":null,"vlizDoi":null}],"children":null,"othrel":null,"othrelrev":null,"ownerships":[{"OrderNr":1,"Surname":"Uhlir","Firstname":"Carolin","Initials":"C.","PerPublicFlag":1,"AdrID":164570,"Email":"carolin.uhlir@senckenberg.de","InsPublicFlag":1,"Acronym":"DZMB","OrigNameLangCode":"de","OrigNameLangID":13,"FullOrigName":"Senckenberg am Meer; Deutsches Zentrum fur Marine Biodiversitätsforschung","InsOwnerCNT":1,"PersID":40299,"InsID":4650,"FullInstitute":"Senckenberg am Meer; German Centre for Marine Biodiversity Research","RoleID":59,"Role":"Principal Investigator","OrigName":"Deutsches Zentrum fur Marine Biodiversitätsforschung","StandardName":"German Centre for Marine Biodiversity Research","FullAcronym":"DZMB","ORC":null,"ROR":null}],"taxterms":[{"DasTaxtTypID":1,"DasTaxtType":"Taxonomic coverage","TaxtID":11310,"TaxTerm":"Animalia","AphiaID":2,"DutchTerm":"Dieren"}],"frameworks":null,"otherterms":null,"temporal":[{"DasDateID":5979,"StartYear":null,"EndYear":null,"StartDay":null,"EndDay":null,"StartDate":null,"EndDate":null,"DasDate":null,"Resolution":null,"ResolutionNL":null,"Notes":null,"StartMonth0":null,"StartMonth":null,"StartMonthNL":null,"EndMonth0":null,"EndMonth":null,"EndMonthNL":null,"Progress":null,"ProgressNL":null}],"geographical":[{"GeoTerm":"German part of the North Sea","DasGeoID":13914,"DasGeoTerm":"Harbour of Rostock","DasID":8358,"GeotID":9428,"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":22762,"OrigGeoTerm":"German part of the North Sea","DutchTerm":null}],"meastypes":[{"MethID":null,"DasMeasTypID":14612,"DasMeasType":"eDNA","Matrix":"Water","MatrixNL":"Water","Parameter":null,"ParameterNL":null,"Description":null,"Unit":null,"Methodology":null,"Protocol":null,"QualityControl":null,"Precision":null,"Detectionlimit":null,"Instrument":null,"InstrumentUrl":null,"MethFull":"","ParaCategoryTitle":null,"ParaCatCode":null}],"dasthemes":[{"DasThemeID":21,"DasTheme":"Biology","DasTheme0":"Biology","DutchTerm":"Biologie"},{"DasThemeID":72,"DasTheme":"Biology > Plankton > Zooplankton","DasTheme0":"Zooplankton","DutchTerm":"Zooplankton"}],"projects":[{"ProID":4928,"Acronym":"GEANS","Progress":"Completed","StandardTitle":"Genetic Tools for Ecosystem Health Assessment in the North Sea Region","FP7Code":null,"GrantDOI":null,"FunderID":"38-2-22-18","FunderIDType":"EU contract id","FunderCodes":["Other EU initiatives out of framework"]}],"refs":null,"urls":[{"URL":"https://mda.vliz.be/archive.php?folder=8710","externalID":null,"URLTypeCode":null,"URLType":"Additional info","URLTypID":37,"downloadURL":null,"FileName":null},{"URL":"https://northsearegion.eu/geans/","externalID":null,"URLTypeCode":null,"URLType":"Additional info","URLTypID":37,"downloadURL":null,"FileName":null},{"URL":"https://www.vliz.be/projects/geans","externalID":null,"URLTypeCode":null,"URLType":"Additional info","URLTypID":37,"downloadURL":null,"FileName":null}],"pictures":null,"urlmaps":null,"spatreps":null,"fileformats":null,"resmessage":"","complete":1}
