The Free Oscillations of Lake Erie


Book Description

The longitudinal free oscillations of Lake Erie are investigated theoretically by numerical integration of the channel equations, and observationally by analysis of water-level covariance spectra. Good agreement is obtained between computed and observed periods of the first four modes, as well as between computed and observed amplitude. Particular attention is given to influence of the earth's rotation and to the effect of friction. The general conclusions are that the earth's rotation transforms the lowest longitudinal mode into an amphidromic wave with countererclockwise rotation of cotidal lines, but does not significantly affect the period of any mode.

Limnological Survey of Eastern and Central Lake Erie, 1928-29


Book Description

Abstract: Results of a cooperative survey of the central and eastern basins of Lake Erie in 1928-29 by the U.S. Bureau of Fisheries, New York State Conservation Department, Ontario Department of Game and Fisheries, Health Department of the City of Buffalo, and the Buffalo Society of Natural Sciences are presented in a series of papers. Physicochemical data include seasonal, vertical, and horizontal variations in temperatures, water movements, dissolved oxygen, carbon dioxide, phenolphthalein and methyl-orange alkalinity, pH, chlorides, and turbidity. The species composition, seasonal abundance, and distribution of micro- and macroplankton are discussed in detail. Special consideration is given to the influence of polluted river waters which flow into the lake. It is concluded that the lake is remarkably free from chemical and sewage pollution. Evidence of pollution farther than 1 mile from possible sources was detected at only 2 stations. The nutrient level of Lake Erie is high and the lake should support large fish populations.

A Study of Progressive Oscillatory Waves in Water


Book Description

Observations of wave motion phenomena in nature are essential, but laboratory studies leading to the evaluation of existing theories may be invaluable as a guide to field observation programs and technique. The purpose of the study is to seek laboratory experimental confirmation of oscillatory wave characteristics.
