This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This progress report begins with a summary of research activities during the past three years and ends with eleven appendices as supplemental reference materials. In the following summary, brief narratives were prepared integrating the reports under the following headings: nearshore processes, mixing and water transport, phytoplankton nutrient enrichment experiments, and ecosystem analyses. The purpose of the summary is to point out the significance of research efforts with reference to broader environmental questions than those which have been studied. The appended materials are in various stages of completion, ranging from reports which have been published, manuscripts which have been submitted for publication and manuscripts which are being readied for publication.

Data were collected on species composition and abundance of phytoplankton and on chlorophyll a, primary productivity, phosphorus silica, nitrate, ammonia, pH, chloride, specific conductance, water temperature, and transparency. Open lake studies confirmed a predicted shift in species composition from diatoms to blue-green algae in the epilimnetic waters and offered evidence that silica limitation is the major factor restricting diatom abundance. Studies on tributaries showed great differences in chemical parameters and phytoplankton composition in the three rivers, Grand, Kalamazoo, and St. Joseph. Cruises were conducted to study the Grand River and the Grand River plume in Lake Michigan; it was found that nutrient levels were high during high flow conditions regardless of the time of year. Chemostat studies are being conducted with diatoms. (HLW).

Emphasis was placed on an area near Holland, Michigan where typical summer mixing patterns of the Kalamazoo River plume between the nearshore zone and mid-lake water mass were studied. Results showed that the nutrient load of the river's tributaries studied had a marked effect on the nearshore zone and the standing crop and species composition of phytoplankton. Data are included on the content of phosphates, silica, nitrates, chlorides, and chlorophyll, pH, and temperature of water samples collected from various locations during different seasons.

This book was released on 2010-10-17 with total page 402 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eutrophication continues to be a major global challenge to water quality scientists. The global demand on water resources due to population increases, economic development, and emerging energy development schemes has created new environmental challenges to global sustainability. Eutrophication, causes, consequences, and control provides a current account of many important aspects of the processes of natural and accelerated eutrophication in major aquatic ecosystems around the world. The connections between accelerated eutrophication and climate change, chemical contamination of surface waters, and major environmental and ecological impacts on aquatic ecosystems are discussed. Water quality changes typical of eutrophication events in major climate zones including temperate, tropical, subtropical, and arid regions are included along with current approaches to treat and control increased eutrophication around the world. The book provides many useful new insights to address the challenges of global increases in eutrophication and the increasing threats to biodiversity and water quality.
