Production, fate and effects of new DOM in a coastal ecosystem

Updated 2002-08-28

Four-week mesocosm study with the following objectives: - to identify environmental and biotic factors in control of the production, chemistry and fate of exportable DOM in a coastal environment - to follow how DIN and DIP are transformed to DON and DOP and to measure their mineralisation - to analyse the optical properties of new DOM and to measure how radiation might change the optical properties - to validate current community-nutrient models for the marine system with particular emphasis on the mechanisms regulating shifts between carbon- and mineral nutrient limitation of bacterial growth rates, - to produce experimental data for further development and modification of the plankton community-nutrient model and – to incorporate DON and DOP into the present community-nutrient model.
