Patterns of sediment accumulation in the Siletz River Estuary, Oregon

Creator:: Pakenham, Anna
Abstract:: Anecdotal evidence suggests many Pacific Northwest estuaries are filling with sediment due to historical logging activities in upstream watersheds. Using the Siletz River estuary as a case study, this research began by analyzing timber harvest and discharge records of the Siletz River watershed, and found that increased timber harvest coincides...

Understanding the anodic mechanism of a seafloor fuel cell

Creator:: Ryckelynck, Natacha
Abstract:: Anoxic sediment overlain by oxic seawater establishes a voltage gradient on the order of 0.7-0.8V across the sediment-water interface. This study follows Reimers et al. (2001) and Tender et al. (2002) who reported the development of a seafloor fuel cell to harvest electrical energy from this potential difference. Prototype fuel...

Sensitivity of a subregional scale atmospheric inverse CO₂ modeling framework to boundary conditions

Creator:: Göckede, Mathias, Turner, David P., Michalak, Anna M., Vickers, Dean, and Law, Beverly E.
Abstract:: We present an atmospheric inverse modeling framework to constrain terrestrial biosphere CO₂ exchange processes at subregional scales. The model is operated at very high spatial and temporal resolution, using the state of Oregon in the northwestern United States as the model domain. The modeling framework includes mesoscale atmospheric simulations coupled...

Modeling the detection range of fish by echolocating bottlenose dolphins and harbor porpoises

Creator:: Au, Whitlow W. L., Benoit-Bird, Kelly J., and Kastelein, Ronald A.
Abstract:: The target strength as a function of aspect angle were measured for four species of fish using dolphin-like and porpoise-like echolocation signals. The polar diagram of target strength values measured from an energy flux density perspective showed considerably less fluctuation with azimuth than would a pure tone pulse. Using detection...

Testing the odontocete acoustic prey debilitation hypothesis: No stunning results

Creator:: Benoit-Bird, Kelly J., Au, Whitlow W. L., and Kastelein, Ronald A.
Abstract:: The hypothesis that sounds produced by odontocetes can debilitate fish was examined. The effects of simulated odontocete pulsed signals on three species of fish commonly preyed on by odontocetes were examined, exposing three individuals of each species as well as groups of four fish to a high-frequency click of a...

The Costa Rica Dome : a study of physics, zooplankton and blue whales

Creator:: Matteson, Robyn S.
Abstract:: At the Costa Rica Dome (CRD), upwelling associated with cyclonic circulation and the presence of a shallow thermocline support a highly productive biological habitat, exploited by marine fauna at several trophic levels. During January 2008, a cruise to the CRD by the R/V Pacific Storm was conducted to relocate blue...

Swash zone sediment suspension and transport

Creator:: Puleo, Jack A.
Abstract:: Swash zone processes are of significant importance to foreshore morphologic change. This thesis addresses the importance of the uprush and backwash fluid motions and flow duration effects to the resulting sediment transport. The analysis relates the field observations to well known sediment transport formulations as well as investigates the importance...
