Abstract
Review of Long Term Turbidity Trends with Possible Reasons around the World
Highlights
Turbidity trends in different parts of the worldTurbidity as a measure of water clarity, especially high turbidity reduces the amount of light penetrating water, photosynthesis, production of dissolved oxygen, disease resistance of fish, growth rates and egg development of especially benthic macro organisms.In the Baltic Sea, phytoplankton biomass increased due to eutrophication and water clarity decreased between 1969 and 1991 [1]
In spite of no overall trend observed in 1987-1997 for the Irish Sea, annual variations in turbidity were found as correlated with regional wind strength and it was suggested that the turbidity in coastal seas was controlled by climate [13]
While a decreasing trend in the water clarity of the Menai Strait, UK from the 1960s to1980s did not continue in the 1990s and 2000s [14], it was suggested that turbidity in the strait was mostly due to inorganic sediment, not organic or sewage and the changes in turbidity were driven by changes in wind, in other words climate [14,15]
