Abstract

Measurements of the vertical absorption coefficients, and their seasonal variations, of several spectral bands of visible light have been made at two selected stations. One station was located in the Strait of Juan de Fuca near Cape Flattery and the other in Hood Canal near its junction with Puget Sound. Variations were found at both stations which indicate some evidence of correlation between the growth of microscopic life and the penetration of daylight into these waters.
