Abstract

Abstract The carbon exchange of the Wadden Sea Salt marsh near the Lutjewad Weather station is investigated during a period of 7 weeks. Three vegetation species are studied: Elymus Athericus, Festuca Rubra and Spartina Towndensii. The average carbon sequestration for the 25th and the 26th of May is estimated on 14 μmol m-2 s-1 for Elymus Athericus and on 4 μmol m-2 s-1 for all species. This high difference is caused because the value of 14 μmol m-2 s-1 is measured on one position, where the circumstances were optimal. Elymus and Festuca have corresponding GPP. However, the respiration rate for Fesuta Rubra is lower. Spartina was only just starting its growing season, so the GPP was much lower than that of the other two species. Besides solar irradiance, temperature is found to be a significant factor for the total gross primary production (GPP). Tidal factors may also influence GGP. Higher biomass seems to correspond to higher respiration rate, although the data was obscured by scatter. Our measurements with the closed chamber technique agreed closely with nearby eddy-correlation data.
