Hydrographic data from Oregon waters 1962 through 1964

Creator:: Wyatt, Bruce and Gilbert, William E.
Abstract:: This is the fifth report of data collected during a study designed to determine the currents and water masses along the Oregon coast. The first four reports cover the period from July 1958 to December 1961 (Wyatt and Callaway, 1961; Wyatt and Kujala, 1961; Wyatt and Kujala, 1962; Wyatt and...

Dynamics of organic matter production and degradation during coastal diatom blooms

Creator:: Wetz, Michael S.
Abstract:: Experiments were designed to answer key questions about diatom-derived organic matter cycling (i.e., production and degradation) in coastal systems. Dissolved organic matter (DOM) production was examined in axenic batch cultures of five diatom species. Dissolved organic carbon (DOC) release rates varied between species, but were significantly higher for all species...

Stream metabolism and suspended sediment concentration data from two streams in the Oregon Coast Range

Creator:: Segura, Catalina, Cargill, Samantha K., and Warren, Dana
Abstract:: This dataset includes the datasets of suspended sediment concentration and environmental variables used to model stream metabolism, and the modeled stream metabolism results for two streams. For more information, see Cargill, SK (2019). The Influence of Lithology on Stream Metabolism in Mountain Systems. MS Thesis, Oregon State University.

Influence of upwelling-season coastal currents on near-bottom dissolved oxygen concentrations over a submarine bank

Creator:: Adams, Katherine A.
Abstract:: Wind-driven coastal upwelling brings subsurface water onto the central-Oregon shelf after the spring transition each year. This cold and salty source water is oxygen-poor, yet above the hypoxic threshold, dissolved oxygen < 1.4 ml l⁻¹. Once on the shelf, dissolved oxygen (DO) concentrations of upwelled near-bottom waters are modified by...

Modeling the impact of logging debris on the dissolved oxygen balance of small mountain streams

Creator:: Berry, John David
Abstract:: Previous research has indicated that considerable amounts of finely divided slash accumulate in small mountain streams following timber harvesting. The subsequent biological decomposition of this organic matter can result i.n the reduction of dissolved oxygen (DO) concentration to levels as low as 0.6 ppm. These DO levels are lethal to...

Bridge over troubled water : partnerships and the prospect of adaptive capacity among small Oregon coast water systems

Creator:: Dennis, Lauren Marie
Abstract:: The Oregon Coast's small water systems, like the vast number of small water systems across the U.S., are greatly vulnerable. Failing infrastructure, limited financial capital, and inadequate staff combined with future changes in climate, population size, and regulatory stringency spell out a potentially dire future for the region's water supply...

Evaluating Oregon's beach sites and assessing twenty-six coastal beach areas for recreational water quality standards

Creator:: Benedict, Rae T.
Abstract:: With congressional passage of the BEACH Act in October of 2000, Coastal and Great Lakes states were mandated to assess coastal recreation waters for the application of ambient water quality standards. This research encompasses two components involved in applying the BEACH Act statues to Oregon. The first component was to...

The role of oxygen and other environmental variables on survivorship, abundance, and community structure of invertebrate meroplankton of Oregon nearshore coastal waters

Creator:: Eerkes-Medrano, Dafne I.
Abstract:: The high productivity of Eastern Boundary Upwelling Ecosystems (EBUE), some of the most productive ecosystems in the globe, is attributed to the nutrient rich waters brought up through upwelling. Climate change scenarios for coastal upwelling systems, predict an intensification of coastal upwelling winds. Associated with intensification in upwelling are biogeochemical...

Population characteristics and movement patterns of redband trout (Oncorhynchus mykiss) and mountain whitefish (Prosopium williamsoni) in the Crooked River, Oregon

Creator:: Nesbit, Shivonne M.
Abstract:: Over the last decade, the Oregon Department of Fish and Wildlife (ODFW) has documented a precipitous decline in the Crooked River redband trout (Oncorhynchus mykiss) population, prompting this study to address potential factors contributing to the decline. There are two main goals to this project: (1) identify potential factors contributing...

Foraging behavior of the Pacific harbor seal (Phoca vitulina richardii) in the Pacific Northwest and potential impacts of coastal hypoxia on foraging efficiency

Creator:: Steingass, Sheanna M.
Abstract:: In the last decade, the California Current Large Marine Ecosystem has experienced a trend of increased severity of upwelling-driven coastal hypoxia. This thesis strove to examine the potential upper trophic level impacts of moderate and severe hypoxia in the CCLME. Initially I conducted a literature review of Pacific harbor seal...
