The extent and mechanism of energy dissipation has been studied in Coos Bay, a coastal plain estuary. Coos Bay is located on the central Oregon coast, 184 nautical
miles south of Astoria, Oregon, and 35 nautical miles north of Cape Blanco. Past field work in Coos Bay and data obtained...
Side-scan sonar records in Oregon's Coos Bay estuary navigation
channels were obtained at intervals of two to three months during the
November 1974 - October 1975 time period from Coos Bay Channel Mile
11+50 to 15+20, and from a reach in the Marshfield Channel. A limited
side-scan survey effort was...
Tidal marshlands in the upper estuary ecotone provide essential habitat for
juvenile salmonids. In this environment, salmonids grow rapidly and acclimate to
saltwater. Worldwide, tidal marshes have been diked and drained to provide
agricultural and residential land. Tide gates are one-way doors integrated into
dike systems that prevent saltwater flooding...
The Army Corps of Engineers dredged in Coos Bay in the fall of 1948, dumping dredge spoils on a large clam bed and killing the clams. Although Fish Commission biologists were unable to relocate the original planned dumping site, they observed the resulting increased pressures on remaining clam resources, and...
