Wadden Sea is an important habitat for both harbour and grey seals. Harbour porpoises and Atlantic white-beaked dolphins, which once were locally extinct but have re-colonized the area, are the sea's only resident cetaceans. Many other species have disappeared, only visit seasonally, or occasionally. North Atlantic right whales and gray whales were once seen in the region, using the shallow Inscription: (33rd Session). 1. Introduction. Wadden Sea research has its roots in the 19th century when all along the European coasts marine laboratories were established. In the Netherlands, the Zoological Station of the Dutch Zoological Society was the first marine field station (van Bennekom, ).This first station was movable and has served as a laboratory at various places along the Dutch by: Bulk land-derived organic matter in Dabob Bay contains a maximum of 50% vascular plant debris and comprises an average of one-third of the total organic carbon in the sediment trap samples and two. The Wadden Sea is a shallow tidal area along the North Sea coast of The Netherlands, Germany and Denmark. The area is strongly influenced by rivers, the most important of which are the rivers Rhine, Meuse and Elbe. Due to the increased nutrient load into the coastal zone the primary production in the Wadden Sea almost tripled during the past few by:

Marine dissolved organic matter (DOM) is a complex mixture of molecules found throughout the world's oceans. It plays a key role in the export, distribution, and sequestration of carbon in the oceanic water column, posited to be a source of atmospheric climate regulation. Role of Soil Organic Matter. Once a land manager begins working towards enhancing soil organic matter, a series of soil changes and environmental benefits follow. The rate and degree of these changes and the best suite of practices needed to achieve results vary with soil and climate.
Traditionally, the Wadden Sea Region has been an important agricultural area. Tourism has achieved an important source of employment especially on the islands and some mainland port localities (Sijtsma et al., in this volume).The major German ports of Hamburg, Bremen/Bremerhaven and Wilhelmshaven, the Dutch Eemshaven/Delfzijl and the Danish Esbjerg harbour important by: The “Ecosystem Research Wadden Sea” of provides an appropriate case study for the practicality of these principles, because its integrative approach largely corresponds to the ecosystem approach.

In the East Frisian Wadden Sea anaerobic degradation of organic matter dominated. Schwichtenberg F., Pätsch J., Böttcher M. E., Thomas H., Winde V. & Emeis K.-C., The impact of intertidal areas on the carbonate system. Urban wastewaters contain high concentrations of nutrients and as such, contribute significantly to the mass loadings of nitrogen and phosphorus to coastal waters. The various inorganic forms of nitrogen and phosphorus stimulate aquatic plant growth, and since they are relatively hydrophilic, their.
