Repeated surveys of one area, like time-lapse photography,can be interpreted as a movie to illustrate the dynamics of detectablefeatures. These attributes of remote sensing from aircraft or spacecraftare especially important in coastal and upwelling regions of the oceans,where oceanographic conditions change rapidly. The world's largest fisheriesare also located in these dynamic areas.

As a result, the NLIW field on the New Jersey shelf displayed dramatic variability during the Shallow Water 2006 experiment. Wave variability was exhibited by 1) amplitudes that ranged from 5 m to over 20 m, 2) irregular wave arrival times, and 3) wave forms that were either mode-1 or mode-2 in vertical structure. Over the month-long experiment, a six-day time span, which was coincident with the neap tide, was distinguished by having the largest observed NLIWs. The change in character of the observed waves between this period and the remainder of the month resulted in wave energies that increased by a factor of 5-10. The wave energy budget also varied spatially, as waves propagated across the shelf. On the outer shelf, energy was supplied to the NLIWs by the internal tide; and, inshore the balance shifted so that the change in energy per unit time was balanced by dissipative loss in the waves. While at a particular location dissipation in the core of the waves had only a weak dependence on energy, the average dissipative loss scaled with the maximum energy of the waves. NLIW dissipation was dominated by shear-driven turbulence in the mixed layer; at the pycnocline depth, NLIW dissipation was on average 10 times larger than that observed in background profiles. Consequently, the passage of NLIWs resulted in large heat fluxes across the pycnocline, contributing as much as 50% to the total average heat flux on the shelf. These changes in energetics were accompanied by structural changes in the wave form, including changes induced by wave interactions and the polarity reversal of three large-amplitude wave groups.<br/><br/>Description: Graduation date: 2010 Mon, 21 Sep 2009 15:23:33 GMT http://hdl.handle.net/1957/12583 Title: A historical reconstruction and land use history of six tidal wetlands in Oregon<br/><br/>Authors: Hennessey, Jennifer Taylor<br/><br/>Description: Graduation date: 2005 Tue, 08 Sep 2009 16:50:17 GMT http://hdl.handle.net/1957/12506 Title: A toolbox for sustaining working waterfronts;Assessing applications in Newport, Oregon<br/><br/>Authors: Kellner, Laurel A.<br/><br/>Abstract: Working waterfronts across the nation are under pressure. Land use priorities of local governments are changing in response to population growth, new economic pressures, and shifting policy and politics. In Oregon, the decline of fisheries and timber in economic importance followed by the growth of tourism and retirement services has introduced new challenges for traditional water-dependent activities and land uses.The Community Seafood Initiative and Seafood Consumer Center, in partnership with the Coastal Oregon Marine Experiment Station and Oregon State University, are leading a Pacific Northwest project to identify tools and strategies to sustain working waterfronts. Developing a 21st Century Toolbox is a main component of the research that will support community-specific engagement strategies. Toolbox frameworks developed in previous research for seaport development and waterfront revitalization are adapted to better address sustaining working waterfronts.Based on its prominence as a commercial fishing port and local interest in supporting this industry, the use of the toolbox in Newport, Oregon is investigated. Relevant tools and strategies are identified from the existing waterfront toolbox and modified and expanded into a “toolbox for working waterfronts.” Current applications of strategies to sustain the working waterfront are addressed based on a series of criteria noted in the literature for good processes concerning waterfronts. These criteria are adopted for a potential Model Working Waterfront Program (MWWP) and used to assess Newport in comparison to other working waterfront communities in the United States.Findings indicate that the toolbox is continually evolving and Newport may be underutilizing some of the tools identified for sustaining working waterfronts as compared to other waterfront communities and the criteria for a MWWP. Conclusions on the present status of tool utilization in Oregon and Newport are presented, key areas of improvement are suggested, and recommendations are offered to sustain the state’s working waterfronts.<br/><br/>Description: Graduation date: 2010 Thu, 27 Aug 2009 15:31:22 GMT
