Several physical and chemical characteristics of sediments have
been proposed for use in tiered testing plans to predict the
presence of trace metals in estuarine sediments. Correlations often
exist, but the mere presence of a trace metal does not indicate
toxicity; a more thorough approach is needed.

Appendices include the report "Crisis in Oregon's Estuaries" from the Oregon Chapter of the American Fisheries Society, ordinances of the Port of Toledo, and the petition for what would become the Oregon Beach Bill.
Benthic samples were collected during the summer, winter and
spring seasons from upper Yaquina Estuary, a region used by Georgia-
Pacific Corporation for log dumping and storage. Samples came from
an active log dump and storage areas as well as areas not associated
with log handling activity. The samples were...
Most of the readily available unpublished hydrographic data for Oregon Estuaries which was collected prior to June 1956 have been tabulated, Data on water temperature salinity and velocity are presented. Data collected by the Navy Hydrographic Office and the USC & GS are not included.
Epiphytic diatom assemblages in the intertidal zone of Yaquina
Bay and estuary were obtained from the following host macrophytes:
Zostera marina, Fucus evanescens, and species of Enteromorpha,
Polysiphonia, and Ulva. Samples were collected in September 1970
and in January and May 1971 from seven stations approximately evenly
spaced between the...
This report is largely concerned with the toxicity of Sevin (carbaryl) and Dursban (chlorpyrifos) on aquatic organisms. "The general objective of this research is to investigate the effects of various pesticides, which might be expected or are known to occur in estuaries, on the larval and adult stages of estuarine...
The extent of biological invasions, their role on the feeding of
native fishes and their impact on community stability were
investigated in Alsea Bay and Yaquina Bay, two estuaries on the
central Oregon coast, USA. Most nonindigenous species (NIS)
introduced in these intermediately invaded estuaries are
considered byproducts of culturing...
Unpublished hydrographic data for Oregon Estuaries (Alsea, Columbia, Coos, Nehalem, Netarts, Siletz, Siuslaw, Tillamook, Umpqua, and Yaquina) which was collected by Oregon State College between June 1956 and September 1958 are tabulated.
