Download or read book The Chemical Investigation of Recent Lake Sediments from Wisconsin Lakes and Their Interpretation written by Gilbert Carl Bortleson and published by . This book was released on 1971 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: To trace the effects of cultural eutrophication, one meter sediment cores were used to determine the history of calcareous and noncalcareous Wisconsin lakes. Cores were analyzed for carbon, phosphorus, calcium, magnesium, potassium, aluminum, iron, and manganese. Determinations of organic nitrogen, exchangeable ammonium and acid soluble phosphorus were made on selected sedimentary profiles. Recent sedimentation rates and identification of pre- and postcultural sediments were determined by ragweed pollen. Enrichment of phosphorus in postcultural Lake Mendota, Wisconsin, sediments are the effect of increased phosphorus supply from domestic sewage. Chemical stratigraphy of concentration-depth diagrams permit a qualitative evaluation of cultural activities. Potentialities and limitations of using recent lake sediments to evaluate eutrophication are discussed.

Download or read book Algae Abstracts written by Office of Water Resources Research Staff and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 590 pages. Available in PDF, EPUB and Kindle. Book excerpt: Algae Abstracts is the first in a series of bibliographies on water re sources and pollution published by IFI/ Plenum Data Corporation in cooperation with the Water Resources Scientific Information Center (WRSIC). It is produced wholly from the information base compris ing material abstracted and indexed for Selected Water Resources Abstracts. The bibliography is divided into volumes according to the publication dates of the source documents. Volume 1 contains 569 abstracts cov ering publication dates up to and including 1969; Volume 2 contains 730 abstracts covering the years 1970 to 1972. The material included in this bibliography represents computer selections based on the presence of a form of the word "alga" somewhere in the referenced citation. Substantively, the material typifies WRSIC's "centers of com petence" approach to information support of the Office of Water Re sources Research (OWRR) of the Department of the Interior. Most of the references in this bibliography are the work of the center of competence on eutrophication at the University of Wisconsin. The indexes refer to the WRSIC accession number, which follows each abstract. The Significant Descriptor Index is made up of a fraction of the total descriptors and identifiers by which each paper has been indexed. It represents weighted terms that best describe the informa tion content; this status is indicated by the asterisks which precede them. The General Index includes all the remaining descriptors and identifiers by which each paper in this bibliography has been indexed.

Download or read book Limnological Aspects of Recreational Lakes written by Kenneth Marsh Mackenthun and published by . This book was released on 1964 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Limnological Aspects of Recreational Lakes" considers the many problems associated with the recreational use of lakes, reservoirs, and ponds. These standing-water bodies receive the most concentrated and varied recreational use of any waters, and provide enjoyment to the greatest number of people. Individuals using such areas soon become aware of associated biological problems and often demand remedial measures to alleviate developing nuisances or the prevention of them before they arise. This book is written for the person faced with problems of interpretation and management in dealing with the phenomena of recreational lakes. In most States, a permit or permission must be obtained from an appropriate agency prior to the institution of controls. Then controls are instituted, the recommended controlling agent and its field application must be tempered with a scientist's astute knowledge of both the problem and the ecological ramifications of a control program.
