The algae explosion is most evident in Lake Erie, where warm, shallow waters get heavy loads of nutrient runoff from farms in western Ohio. But blue-green cyanobacteria blooms have been spotted. Nutrients are chemical elements critical to the development of plant and animal life.

In healthy lakes and streams, nutrients are needed for the growth of algae that form the base of a complex food web supporting the entire aquatic most common nutrients in lakes and streams are nitrogen and phosphorus.

Lake Superior is the largest of the Great Lakes of North America, the world's largest freshwater lake by surface area, and the third largest freshwater lake by is shared by the Canadian province of Ontario to the north, the U.S. state of Minnesota to the west, and Wisconsin and the Upper Peninsula of Michigan to the south.

Introduction. Lake Superior is the largest freshwater lake in the world by surface area and the third largest by volume, storing 10% of the world's available fresh water (Kalff, ).The Lake Superior basin offers natural resources including fisheries, agriculture, shipping, tourism, and industry such as pulp and paper mills, timber logging, and mining (LakeNet,GLIN (Great Lakes.

The formation of large swaths of cyanobacterial biomass across Lake Erie is not a new phenomenon. Beginning in the early twentieth century, a marked increase in phytoplankton biomass and a decline in dissolved O 2 were primarily thought to be a result of phosphorus loading via point sources into the system (Charlton et al., ).While largely comprised of diatoms, the Lake Erie.

Nutrients And Sediment In The Western Lake Erie Basin. Science Center Objects. Overview; Partners; Sediment and nutrient runoff (nitrogen and phosphorus) from agricultural and urban land-use practices are of great concern in the Western Lake Erie Basin watersheds.

Excessive nutrient inputs can lead to algal blooms that deplete the oxygen. To investigate the carbon cycle of Lake Superior, Earth's largest freshwater lake by surface area, we performed total organic carbon, dissolved organic carbon, chlorophyll, spectrophotometric pH, total inorganic carbon, and alkalinity measurements on seasonal samples from the western lake.

Inputs from urban and agricultural areas, on a percentage basis, were relatively similar for each Great Lake, except Lake Superior.

P from point sources represented ∼% of the total input to each lake, except for Lake Superior for which it represented only 14% of the total. The largest source to Lake Superior was from forested areas. By the mid 20th century, the lower Saint Louis River became one of the most heavily polluted waterways in the state.

Holling Clancy Holling, in his book Paddle-to-the-Sea, illustrated the polluted state of the Saint Louisthe river became an Environmental Protection Agency Area of Concern.

The St. Louis River (within the Western Lake Superior Basin), also with very low nitrate concentrations, had fairly stable trends at Forbes and Fond Du Lac, with a slight decrease in concentrations at Forbes and a slight increase at Fond Du Lac.

Introduction. Due to the continuous release of contaminants, including phosphorus, from agricultural development in the Maumee River drainage basin of Ohio (Logan, ), nutrients and contaminant loadings have increased in Lake Erie continuously since the 19 th century (Matisoff, ), leading to cultural eutrophication.

Although eutrophication is a natural process, it is easily seen in Lake. A former fencing coach at Harvard University, Peter Brand, was charged with accepting bribes to get the two sons of Jie “Jack” Zhao admitted to the university.

"In total, Zhao made $ million in payments to Brand, or for Brand’s personal benefit, even as Brand recruited Zhao’s younger son to the Harvard fencing team," said a statement from the Justice Department.

Tributaries were ranked based on their relative loads and yields to each lake. Input from agricultural areas was a significant source of nutrients, contributing % of the P and % of the N, except for areas around Lake Superior with little agriculture.

Campus Location: Biomedical Research Building, 9th Floor & WG Adelbert Road Cleveland, OH • Western Lake Superior is experiencing more precipitation, warmer winters, and increasing storm events.

These environmental changes impact human health and well-being in complex ways. But community leaders need to understand climate impacts to human health at the local level in order to prepare their communities for future conditions.
