Diatoms, chlorophyll and carbohydrates in the surface sediments of the Venice Lagoon: effects on the erosione threshold

During the F-ECTS programme carried out in the Venice Lagoon, samples of the surface sadiments were taken in representative areas with the aim of estimating the chlorophyll, colloidal carbohydrates and benthic diatoms contents. The preliminary results showed a good correlation between these parameters and the erosion threshold
