The following study was commissioned by the Oregon State University Extension Service, Oregon Sea Grant College, and the Oregon State Marine Board (OSMB) to address the public transient moorage needs of large craft cruising and sailing vessels on the Lower Columbia River. The study will focus on the Oregon side...
This study is composed of two parts. Section I deals with
developed moorages and marinas--where they are; what services are
offered in each, and how well the existing supply of permanent moorages
serves the boating public. Section II examines the need for temporary
'harbors of refuge' in the area, what...
This study is the second of a three-part project to determine potential locations for public transient tie-up facilities along the Columbia River. The goal of the three studies is to identify opportunities for developing a network of facilities, which will enable recreational boaters to safely traverse Oregon's portion of the...
In this study methods were developed for the prediction of wave
conditions that are hazardous to navigation at river entrances, with
emphasis on applicability to the Columbia River. There are two basic
components to the prediction system: (1) a semi-automated spectral
method for forecasting the significant height and average period...
Hydrographic and bathythermograph data taken off the Oregon
coast during a two week period in August of 1969 were analyzed to
determine if heat content and mixed layer depth may be used as
indicators of Columbia River plume water.
Heat content was found to be a poor indicator of plume...
An intensive chemical investigation, that includes the
determinations of salinity, oxygen, nutrients, pH, alkalinity, and
total carbon dioxide of the Columbia River plume off the Oregon
coast in July 1967 shows the following unique features:
1. Along the axis of the river plume both the salinity minimum and
temperature maximum...
Suspended particulate matter (SPM) in the Columbia River is a mixture of particles of several origins having varying physical and biogeochemical properties. The relative abundances of these freshwater particles changes with season and apparently also with tide. Prior investigation has quantified seasonal variation of organic material in both the Columbia...
