Baseline environmental survey of Pacific Northwest estuaries -- Instrumentation and techniques

Guidelines are needed for the development and protection of Pacific Northwest Estuaries. An inventory of estuarine conditions and resources should be completed and evaluated before industrial construction is permitted. In response to this requirement, Oregon State University under the National Sea Grant Program has initiated a study to measure the characteristics of the estuarine waters of the state. An approach to the determination of the predominent physical, chemical and biological parameters of these waters is presented. Parameters measured, equipment selected or developed and measurement techniques are described in some detail. Implication of the conditions found are discussed.
