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...

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.

Creator:: Poor, Cara J.
Abstract:: This work furthers the understanding of processes occurring in catchments that affect stream nitrate concentrations using two different approaches: a temporally intensive case study of three headwater catchments with varying land use (through storm event monitoring) and a spatially intensive study on the regional scale (through statistical modeling) of 1st-4th...

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...

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...

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...
