The Hudson discharge flows south along the coast due to coriolis force.Further south then are areas of oxygen depletion, caused by chemicals using up oxygen and by algae blooms, caused by excess nutrients from algal cell death and decomposition.Klicken Sie oben auf 'Registrieren', um den Registrierungsprozess zu starten.

It has been suggested that it is the leading worldwide cause of deaths and diseases,and that it accounts for the deaths of more than 14,000 people daily.
Most water pollutants are eventually carried by the rivers into the oceans.
Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen.
Silt-bearing runoff from many activities including construction sites, deforestation and agriculture can inhibit the penetration of sunlight through the water column, restricting photosynthesis and causing blanketing of the lake or river bed, in turn damaging ecological systems.
