A seasonal study of sediment reworking by Neotrypaea californiensis in Yaquina Bay, Oregon

Creator:: Fritz, Cara E.
Abstract:: A year-long field study was undertaken to investigate the influence of a number of physical and biological factors, specifically temperature, organic carbon content, and shrimp population dynamics on sediment reworking rates by the ghost shrimp Neotrypaea calforniensis. Because of its role as a structuring agent in estuaries along the West...

Movement and abundance of lingcod (Ophiodon elongatus) in Yaquina Bay Estuary, Oregon: evidence for essential habitat designation

Creator:: Schwager, Tad W.
Abstract:: Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...

The role of predation by the red rock crab, Cancer productus, on the invasive European green crab, Carcinus maenas, in Yaquina Bay, Oregon

Creator:: Hunt, Christopher Erik
Abstract:: In Yaquina Bay, Oregon, I observed very little overlap in the distribution of the invasive green crab, Carcinus maenas, and the larger red rock crab, Cancer productus. Red rock crabs dominate the more saline, cooler lower estuary and green crabs, the less saline, warmer upper estuary. Because caged green crabs...

Yaquina Bay and South Beach Marina sediment sampling evaluation

Creator:: United States. Army. Corps of Engineers. Portland District
Abstract:: "Nine (9) sediment samples and 1 QC duplicate were collected from Yaquina Bay and South Beach Marina (see Figures 1) on May 31, 2000. All samples were submitted for physical analyses, with 4 samples analyzed for metals (9 inorganic), total organic carbon (TOC), pesticides/polychlorinated biphenyls (PCBs), phenols, phthalates, miscellaneous extractables,polynuclear...

Use of extractable lipofuscin as an age biomarker to determine age structure of ghost shrimp (Neotrypaea californiensis) populations in west coast estuaries

Creator:: Cassidy, Katelyn M.
Abstract:: Determining age in crustaceans is inherently imprecise because they molt periodically and do not retain hard structures throughout their lifespan. Morphological measurements, such as carapace length, are often used to estimate age because methods for direct ageing do not exist. However, variability in individual growth rate and molt frequency can...

Characterization of Vibrio parahaemolyticus isolated from Oregon and Washington coastal water and development of improved methods for Vibrio parahaemolyticus detection

Creator:: Duan, Jingyun
Abstract:: Distribution of Vibrio parahaemolyticus in Oregon and Washington oystergrowing areas was studied between November 2002 and October 2003. V. parahaemolyticus was detected in 14.3% of oyster, 23.0% of seawater, and 44.4% of sediment samples with very low levels (≤7.4 MPN/g) of pathogenic strains being detected in oysters. Occurrence of V....

Utilization of natural and supplemental biofuels for harvesting energy from marine sediments

Creator:: Nielsen, Mark E.
Abstract:: A benthic microbial fuel cell (BMFC) is an electrochemical device that generates current from the redox gradient at the sediment-water interface. Early prototypes had anodes buried in anoxic sediments and cathodes in overlying water. The BMFCs described in this dissertation are based on a chamber design that enables the use...

The development and evaluation of an interactive exhibit to support real-time water quality data interpretation by the public at an informal education setting

Creator:: Mikulak, Sarah E.
Abstract:: Ocean observing groups are currently making efforts to work with well-defined end-user groups, like boaters and fishermen, to provide meaningful and effective real-time data (RTD) products and visualizations. However, providing meaningful data products for undefined groups such as the general public is not straightforward. In Oregon, several industry, science, and...
