Abstract

A method for identifying environmental impacts to estuarine sediments has been developed and applied to Coos Bay, Oregon. This approach is directed towards early phases of environmental impact assessment and appears to be effective for promoting truly interdisciplinary efforts. Physical, chemical and biological characteristics are sketched on a two-dimensional plot of organic content of the sediment (OCS) versus rate of sediment turnover (RST). These plots are overlay ed to given common characteristics. Movements of stations on the plane are identified as chronic impacts.
