Insights from stable isotope dynamics into the sensitivity of larval Pacific oysters to ocean acidification

Creator:: Brunner, Elizabeth Lev
Abstract:: Larvae of the Pacific Oyster, Crassostrea gigas, at Whiskey Creek Shellfish Hatchery (WCH) in Netarts Bay, Oregon, are negatively impacted by high-CO₂ water and exposure during the initial shell formation period appears to be particularly damaging. To investigate the mechanism of this early susceptibility, several cohorts of larvae at WCH...

Remineralization of marine particulate organic matter

Creator:: Burkhardt, Brian Gary
Abstract:: Marine microorganisms play a significant role in the cycling of nutrients in the open ocean through production, consumption, and degradation of organic matter (OM). Carbon (C), nitrogen (N), and phosphorus (P) are essential ingredients in every known recipe for life. However, the cycling of each of these elements proceeds at...

Eddy correlation benthic O₂ exchange rates and characterizations of sediment properties from the central Oregon shelf at 30 meters

Creator:: McCann-Grosvenor, Kristina
Abstract:: Rates of benthic O₂ exchange are important measurements for determining organic matter remineralization, and can shed light on factors driving biogeochemical processes in coastal environments. Measurement of in situ O₂ consumption and production within permeable sediments, such as those found over ~43% of the Oregon-Washington shelf, has traditionally been done...

Submarine plateau volcanism and Cretaceous Ocean Anoxic Event 1a : geochemical evidence from Aptian sedimentary sections

Creator:: Walczak, Paul S.
Abstract:: Marine sediments exceptionally rich in organic carbon, known as black shales, occur globally but intermittently in well correlated Cretaceous successions. The presence of black shales indicates that sporadic, ocean-wide interruption of normal respiration of marine organic matter during oxygen-deficient conditions has occurred. Submarine volcanism on a massive scale, related to...

The distribution and partitioning of dissolved organic matter off the Oregon Coast : a first look

Creator:: Hill, Jon K.
Abstract:: The purpose of this thesis is to provide a first look at the spatial and temporal distributions of dissolved organic material (DOM) off the Oregon coast of North America. While this paper is not a comprehensive examination of these distributions, several patterns are identified as promising candidates for continued research....

Mass spectrometric analysis of bovine neurofilament proteins NF-L, NF-M, and NF-H : peptide mapping, phosphorylation and alkylation site identification

Creator:: Mixon, April E.
Abstract:: Neurofilament proteins are intermediate filaments found in the neuronal cytoskeleton. Phosphorylation of these proteins is considered important for the assembly and stability of the filaments. Accurate molecular weights have been difficult to measure, largely because the high degree of phosphorylation results in M[subscript r]'S that are significantly greater than dictated...

Production and partitioning of organic matter during simulated phytoplankton blooms

Creator:: Wetz, Michael S.
Abstract:: Few studies have examined the partitioning of organic matter in upwelling systems, despite the fact that these systems play a key role in carbon and nitrogen budgets in the ocean. We examined the production and partitioning of phytoplankton-derived organic matter in deck incubations off Oregon during the upwelling season. During...

Geochemical cycling in a Pacific Northwest estuary (Tillamook Bay, Oregon, USA)

Creator:: Colbert, Debbie L.
Abstract:: This thesis investigates the behavior of major inorganic nutrients (P, N, Si), trace metals (Mn, Fe), and alkaline-earth metals (Ba) within Tillamook Bay over seasonal cycles and under a range of river discharge conditions from October 1997 through December 1999. Located in the Pacific Northwest region, Tillamook Bay is an...
