Spatial structure of the physical and biological distributions across the Antarctic Polar Front in austral spring and summer

Creator:: Howard, Cidney
Abstract:: Mesoscale surveys to examine the relationship between the physical processes and biological response along the Antarctic Polar Front (PF) were conducted as part of the US JGOFS Southern Ocean Program during austral spring and summer 1997/98. Multiple crossings of the PF near 170° W, using a towed undulating instrument, provided...

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...

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...

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....

An investigation into nitrogen uptake by Emilania huxleyi during continuous darkness

Creator:: Royer, Ida M.
Abstract:: Experiments were conducted with two strains of the coccolithophorid Emiliania huxleyi. Previous experiments with CCMP1742 and 372 at a light intensity of 60 µEin/m²-s showed that during five-day periods of continuous darkness, strain 1742 was taking up nitrate from the media while strain 372 was not. The nitrate uptake in...

Proof-of‐Concept : Automated high‐frequency measurements of PCO₂ and TCO₂ and real‐time monitoring of the saturation state of calcium carbonate

Creator:: Vance, Jesse M.
Abstract:: The rapid increase in atmospheric carbon dioxide (CO₂) over the last 250 years has led to the absorption of approximately 550 billion tons of anthropogenic CO₂ by the global ocean. This oceanic uptake of CO₂ has resulted in decreasing pH and alterations to carbonate chemistry, threatening many ecologically and economically...

Characterization of organic matter quality and content in Columbia River suspended particulate matter by cupric oxide oxidation

Creator:: Alleau, Yvan M.
Abstract:: The organic content of the Columbia River suspended particulate matter (SPM) results from the input of autochthonous (phytoplankton) and allochthonous (terrestrial vascular plants) production. The contribution of these two sources appears seasonal and responds to factors such as rainfall, runoff, river flow, light and nutrients availability. While numerous studies have...

Physical hydrography and nutrient nitrogen budget of Auke Bay, Alaska

Creator:: Kirk, Deborah Kathleen
Abstract:: Physical sources of nutrient nitrogen for the Auke Bay, Alaska estuarine ecosystem were investigated. These sources included vertical dispersion, advection, and fresh water sources. Hydrographic circulation patterns for the bay, and a nutrient budget for the surface mixed layer were developed. Measurements of temperature, salinity, currents, wind velocity, rainfall and...
