Eutrophication in coastal environments - MarineSpecies Introduced Traits Wiki
It is usually treated in science and management as a local or regional phenomenon, but eutrophication is actually, like climate change, a global issue. The different processes and possible effects of coastal eutrophication on the marine ecosystem are well documented    Fig. Eutrophication causes structural changes throughout the marine ecosystem and reduces ecosystem resilience.
Eutrophication issues are often divided into three groups :. The following responses to increased nutrient inputs are observed in the Baltic Sea :. Phytoplankton is at the base of pelagic food webs in aquatic systems. As the turnover time is less that a few days, it respond rapidly to nutrient concentration changes.
Changes are observed in:.
Submerged aquatic vegetation is affected by eutrophication through :. Oxygen depletion, or hypoxia , is a commonly observed phenomenon low in the water column . Invertebrate benthic fauna can cope with oxygen depletion to varying degrees days — month . If O 2 drops to zero and H 2 S is released all organisms are killed immediately. Mobile benthic invertebrates in sediment move to the surface when O 2 decreases - catches of fish and crustaceans are increased under such conditions.
Eutrophication in coastal environments
It is difficult to predict when animals will return after anoxic episodes. The size of the affected area plays a role: Global warming is predicted to increase hypoxia conditions. A 4 degree temperature increase is projected to result in a doubling of hypoxia in some parts of North Sea. For example, eelgrass is very sensitive to low oxygen concentrations, and dies off under these conditions often in combination with high temperatures. He has more than 20 years experience with international environmental policy-making in the North Sea area.

In this position he was responsible for the coordination of quality assessments of the international Wadden Sea ecosystem and closely involved in the elaboration of North Sea quality status reports. He now co-ordinates the activities of the trilateral Wadden Sea Forum, a platform of stakeholders from the Wadden Sea region, working on sustainable development perspectives and integrated coastal zone management. Marine Eutrophication in Perspective: Twelve invited papers offer finished description and research of the popularity, description and modeling of actual, chemical and organic tactics governing the destiny of toxins in an aquatic setting.
Surroundings the scene with a radical advent to water source concerns, Water Privatisation significantly examines the recent position performed via Trans-National agencies in dealing with and allotting water around the world.
