Three estuaries (Elbe, Schelde and Gironde) were sampled intensively during a 1-week campaign in 1993 and 1994. The campaigns consisted of a sampling transect through the estuary, a 24-h anchor station, followed by another transect. During the campaigns basic hydrographic measurements were made with frequent CTD casts, and water was sampled for nutrients, organic matter, plankton, primary production and bacterial activity. The flocs of suspended material were analysed by in situ cameras. Experiments were conducted with zooplankton and hyperbenthos collected during the campaign.
