A comprehensive evaluation of product quality in the Pacific Whiting (Merluccius productus) and Albacore tuna (thunnus alalunga) industries

Creator:: Greene, Elizabeth
Abstract:: In the highly competitive animal protein market, seafood faces increasing pressure to improve and standardize product quality. While there is general consensus that quality can be improved for many seafood products, there is little agreement on the types and levels of characteristics that should define "quality." This is a fundamental...

Application of nitrogen stable isotopes to identify sources of nutrient pollution : a management tool?

Creator:: Redon, Elizabeth A.
Abstract:: Nutrient pollution may perhaps be one of the oldest water quality problems and has recently been considered as one of the greatest threats to estuarine and coastal waters. Excessive nutrient loads have had a vast array of impacts on estuarine and coastal ecosystems globally. Direct negative effects include: shading out...

The Sensitivity of the Coastal Management Framework Within Oregon to Climate Change and Variability

Creator:: Arden, Elizabeth P.
Abstract:: A heightened awareness to climate phenomena such as the El Nino Southern Oscillation, Pacific Decadal Oscillation, and global warming has initiated much research concerning the impacts of climate change and variability on coastal resources. These events are perceived to exacerbate existing chronic natural hazards, including beach and dune erosion, sea...

Particle size characterization of historic sediment deposition from a closed estuarine lagoon, Central California

Creator:: Watson, Elizabeth Burke, Pasternack, Gregory B., Gray, Andrew B., Goñi, Miguel, and Woolfolk, Andrea M.
Abstract:: Recent studies of estuarine sediment deposits have focused on grain size spectra as a tool to better understand depositional processes, in particular those associated with tidal inlet and basin dynamics. The key to accurate interpretation of lithostratigraphic sequences is establishing clear connections between morphodynamic changes and the resulting shifts in...

The inherent optical properties of the oceans: from closure to prediction

Creator:: Barnard, Andrew Heath
Abstract:: Precise in situ measurement of the spectral absorption and scattering coefficients in several regions has revealed patterns in the distribution of the inherent optical properties on spatial scales that were previously unobtainable. The precision of the measurements was found to be consistent and unbiased across a variety of oceanic regimes...

Feeding rates of the mud shrimp Upogebia pugettensis and implications for estuarine phytoplankton abundance

Creator:: Griffen, Blaine D.
Abstract:: The suspension-feeding mud shrimp, Upogebia pugettensis, is a common inhabitant of intertidal mudflats in estuaries throughout the Pacific Northwest, where it develops extensive burrows. Also inhabiting the shrimps' burrow is the commensal bivalve, Cryptomya californica. Filtration by dense populations of the shrimp and its commensals may have a negative impact...

Relationships of in situ spectral absorption, pigment ratios and environmental parameters for phytoplankton assemblages in coastal waters

Creator:: Eisner, Lisa B.
Abstract:: In situ optical measurements of spectral absorption and beam attenuation provide information on the fine scale horizontal and vertical variations in phytoplankton pigments and other measures of phytoplankton photophysiology and ecology in coastal waters. Phytoplankton pigment ratios from discrete sample analyses with High Performance Liquid Chromatography were compared to in...

Nitrogen isotopes in a global ocean biogeochemical model : constraints on the coupling between denitrification and nitrogen fixation

Creator:: Somes, Christopher J.
Abstract:: We present a new nitrogen isotope model incorporated into the three-dimensional ocean component of a global Earth System Climate Model designed for millennial timescale simulations. The model includes prognostic tracers for the stable nitrogen isotopes, ¹⁴N and ¹⁵N, in the nitrate (NO₃ˉ), phytoplankton, zooplankton, and detritus variables of the marine...

Decomposition of absorption coefficients and decorrelation lengthscales of hydrographic and inherent optical properties in the Middle Atlantic Bight

Creator:: Simeon, Jennifer J.
Abstract:: This investigation is an exploration of the use of inherent optical properties towards further elucidation of coastal circulation processes occurring on the continental shelf and slope in the Middle Atlantic Bight, south of Cape Cod Massachusetts, during 14-Aug to 1-Sep 1996 and 25-Apr to 15-May 1997. Assessing the possibility of...
