Collecting water samples EMODnet Chemistry Current Status Parameters in seawater
EMODnet Chemistry Current Status • Pigments: Filter 500-2500 ml seawater with GF Watmann filter 47mm (sent to Ugent-PAE for analyses) • Nutrients: Filter about 500ml seawater with 0.2 um cellulose-acetate filter for residual water for nutrient analysis (sent to Southampton, National Oceanography Centre) • SPM: One liter unfiltered seawater collected.
Collecting water samples EMODnet Chemistry Next steps Parameters in seawater
EMODnet Chemistry Future steps • Additional parameters measured since 2012 • Additional pigment data? Useful? • Data archeology project • Heavy metals • Additional fertilizers
EMODnet Chemistry Difficulties • No Guidelines for choosing parameters? • Different users may choose • Different parameters
