Major economic resources are used to protect coastal and marine environments from the impact of inorganic nutrients exported from land. However, the export of terrestrial dissolved organic matter (DOM) and its effects have been neglected despite that DOM is one of the most important ecosystem communicators of nutrients, oxygen demand, and light absorption. Without consideration of the export, fate and effects of DOM, environmental protection might fail. In this for four climatic zones. Specific attention is directed to study the transport, storage and cycling of DON, DOP and DOC.
The results will be used to simulate how land-use practice can be applied as a management tool. Experiments in two coastal areas will produce new scientific knowledge on the factors in control of autochthonous DOM production.
