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 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 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 http://hdl.handle.net/1957/12404 Title: Process Development: Methodology and Implementation Strategy<br/><br/>Authors: Kearney, Thomas D; Collier, Robert<br/><br/>Abstract: This white paper investigates methods to conduct effective and efficient process development within the context of the NSF funded construction of the Ocean Observatory Facility.; The basis of this process development investigation was the CGSN Sensor Life Cycle project. During the course of this project the sensor life process was developed with CGSN project team members and sensor manufacturers. Initial process collaboration meetings were also conducted across the OOI organization with the Regional Scale Node (RSN) and CyberInfrastructure (CI) implementing organizations. The CGSN Sensor Life Cycle project provided valuable insights into collaborative process development. The input and feedback from CGSN, RSN, and CI captured during the collaborative process development are reflected throughout this white paper.; This white paper focuses on process development within the context of the Ocean Observatories Initiative (OOI) program. OOI process development faces the same challenges as any large organization: Complex cross functional processes, individual contribution vs. standardization, resistance to changing existing processes, organizational silos of activity, reliance on complex technology, remote locations and virtual teams, scarce project resources, and a diverse customer base.; This white paper provides a practical guide and methodology that addresses these challenges. This“how to” guide for process development is comprised of three main components: 1) The Process Development Template, a series of steps for developing processes; 2) the Process Development Implementation Steps, a series of steps for managing process development within an organization; and 3) Step-by-step examples created during the Sensor Life Cycle project that illustrate process development deliverables.; An integral part of process development is leveraging existing best practices. During the CGSN Sensor Life Cycle project, best practice organizations and individuals were identified, contacted, and engaged. The CGSN process project team continues to nurture these relationships, and collect and analyze information.; The OOI Implementing Organizations (IOs) operations and maintenance strategies refer to a Telecom Operations Map (TOM). The TOM, a best practices publication developed by the TeleManagement Forum, is a reference framework for categorizing processes. This white paper discusses how the TOM, the Process Development Template (PDT), and the Process Development Implementation Steps (PDIS) complement each other. Together they provide a complete process development methodology.; The organization of the white paper is as follows. Section 1 provides a general process development methodology overview, and demonstrates the complimentary aspects of the TOM, PDT and PDIS. Section 2 introduces the PDT and describes it in detail. Section 3 provides process development implementation steps that greatly increase the quality, speed, and collaborative nature of process development. Section 4 provides examples of PDT project deliverables, providing insights into understanding the application of the PDT.
