Description 
Summary

The BIOGEST project determined the distribution in the surface water of European estuaries of biogases liable to have major environmental consequences: CO2, CH4, CO, non-methane hydrocarbons, N2O, NH3, DMS, COS, volatile halogenated organic compounds and biogenic volatile metals. Simultaneously to biogas distribution, related parameters and processes were studied which are linked to biogas distribution: nutrients, organic and inorganic carbon, oxygen, respiration, primary production, atmospheric and sediment exchanges. The estuaries investigated were the Elbe, the Ems, the Rhine, the Thames, the Scheldt, the Loire, the Gironde, the Douro and the Sado. Amongst these nine estuaries, the Rhine, the Scheldt and the Gironde were selected for intensive seasonal studies. Results obtained during this project served to develop a biogeochemical model used to i) propose an estimate of the present day biogas emission from European estuaries and, ii) predict future emission versus carbon and nitrogen loadings. This model provides a decision tool for environmental policy. Data on the estuary of the Elbe are held by the 'Institut fur Biogeochemie und Meereschemie' in Hamburg. Data on the Ems and the Rhine are held by NIOO in Yerseke (NL). First Scheldt cruise: 8 - 12 July 1996: 17 stations sampled along the salinity gradient (from 30 to 0). Underway measurements of pH, O2, CO2, CH4, N2O and CO carried out. Intercalibration exercises done for nutrients and organic carbon. First Gironde cruise: 23 - 30 October 1996: 19 stations were sampled along the salinity gradient (from 30 to 0). Underway measurements of pH, O2, CO2, CH4, N2O and CO carried out. Second Scheldt cruise: 9 - 13 December 1996: 15 stations were sampled along the salinity gradient (from 30 to 0). Underway measurements of pH, O2, CO2, CH4, N2O and CO carried out.
