This is the project dataset of the EUROTROPH project. This project aims to improve our knowledge of the metabolic state of coastal ecosystems, which is fundamental in terms of nutrients and carbon cycling/storage. Measurements on the Scheldt estuary and the Scheldt plume were done during 2 cruises with the Belgica RV in november 2002 and april 2003. More information on the EUROTROPH research project is to be found on http://www.vliz.be/imis/imis.php?module=project&proid=1338
