We present a new estimate for the crustal phosphorous sink that results from reactions among seawater, basalt, and sediment blanketing low temperature mid-ocean ridge flank hydrothermal systems. New estimates for global hydrothermal power output, sediment thickness, and the dissolved phosphate concentrations in basement formation fluids indicate that fluid flow through...
The fishing industry in the Pacific Northwest is a dynamic and highly competitive industry that must constantly respond to rapidly changing resource, regulatory and market forces. These forces have already had a significant impact on our fisheries and will continue to do so as we learn more about the biology...
The Oregon 4-H Carcass of Merit Program offers recognition to Oregon State University Extension 4-H members who breed and/or buy, feed, and raise animals whose carcasses meet the “ideal” for red meat: lean, early maturing, high yielding, and containing minimal external fat. This
publication was prepared for 4-H leaders and...
The State of Black Oregon is a statewide report on the social and economic conditions of African Americans in Oregon, focusing on specific areas such as as education, employment, housing, health, criminal justice and child welfare. "The report reveals a persistent gap in the living standards between black and white...
A tool to help commercial fruit growers identify early damage caused by spotted wing Drosophila (SWD) on blueberries (Duke), raspberries (Malahat), strawberries (Seascape), cherries (Bing, Montmorency, and Rainier), and grapes (Pinot Noir, Chardonnay). Includes photos showing each fruit type a day or two after egg laying, 3 to 4 days...
Various methods have been developed to mitigate the adverse effects of the Federal Columbia River Power System on juvenile Pacific salmon out-migrating through the Columbia River basin. In this study, we found that hatchery-reared spring Chinook salmon Oncorhynchus tshawytscha in the river are in varying degrees of health, which may...
The operation of the Federal Columbia River Power System (FCRPS) has negatively affected threatened and endangered salmonid populations in the Pacific Northwest. Barging Snake River spring Chinook salmon Oncorhynchus tshawytscha through the FCRPS is one effort to mitigate the effect of the hydrosystem on juvenile salmon out-migration. However, little is...
We present the geomorphology of the Eastern Samoa Volcanic Province, covering 28,446 km², and depths ranging from ~50-4000 m. A new compilation of available multibeam data reveals 51 previously undocumented seamounts, and delineates major submarine rift zones, eruptive centers, and volcanic plateaus. Moving from a regional to local scale, and...
This thesis is comprised of two articles that examine sympathy, material culture, and ownership in Victorian literature. In the first article, I explore the figure of the heiress in the Victorian literary tradition, focusing on Charlotte Bronte's Jane Eyre and Charles Dickens's Great Expectations. George Eliot marked the heiress figure...
Upwelling in eastern boundary current systems is a primary driver of ecosystem productivity. Typically, peak upwelling occurs during spring and summer, but winter upwelling may also be important to ecosystem functions. In this study, we investigated the hypothesis that winter and spring/summer upwelling, operating through indirect trophic interactions, are important...
