Experiments were done in August and January. No significant
changes in chlorophyll a or diatom community structure
were observed after ten days of...

densities were found to be most...
The life cycle of Callianassa californiensis Dana, 1854, was
studied in the tidal estuary, Yaquina Bay, Oregon. At this latitude
it is largely restricted to intertidal sandy mudflats under predominately

its distribution to a greater extent than does sediment type.
Vertical movement...

Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...
Lingcod are an overexploited fish species in the Pacific Northwest and although there has been extensive study of the habitat requirements of adults, particularly during spawning, relatively little is known regarding the habitat requirements of post-settlement juveniles. Many juvenile fish use structural components of habitat to alleviate the risk of...
Three realms of deposition, Marine, Fluviatile, and Marine-
Fluviatile, are recognized in Yaquina Bay, Oregon, on the basis of
sediment texture and mineralogy. The Marine Realm extends 1.5

Reports on work on jetties at the entrance to Yaquina Bay. The south jetty was considered complete about November 1, 1889, but settling and scour caused a need for more reinforcement. The north jetty was about 1/3 complete. Estimates costs. The goal at the time was for the channel to...
In Yaquina Bay, Oregon, I observed very little overlap in the distribution of the invasive green crab, Carcinus maenas, and the larger red rock crab, Cancer productus. Red rock crabs dominate the more saline, cooler lower estuary and green crabs, the less saline, warmer upper estuary. Because caged green crabs...
This report describes sediment testing done on the Yaquina River benthos between river miles 6 and 11 (a section between Yaquina and Toledo). The sediments were found to be safe for in-water disposal, thus enabling dredging to proceed.
The report consists of notes of a conversation between Lowell D. Marriage of the Oregon Fish Commission and Jess Hayes, an oyster grower from Bay City, regarding Mr. Hayes' recollections of the history of Pacific oyster culture in Tillamook Bay. Mr. Hayes' account goes back to 1931 and gives estimated...
The United States' declaration of war on Germany on April 6, 1917 imparted some urgency to harbor improvements. This document describes proposed projects at Yaquina Bay: to extend the south jetty, repair and extend the north jetty, construct a spur jetty and dredge the channel.
