Measuring Bubble Pressure in Glacier Ice

Creator:: Clonch, Cameron E.
Abstract:: Recent observations of tidewater glaciers find that the currently accepted model for predicting ice melt vastly underestimates observed melt rates. The release of pressurized air bubbles into the ocean from pores in the ice is one process that can amplify glacier melt. To incorporate this process into models, we need...

Applying climate change information to hydraulic and hydrologic transportation infrastructure

Creator:: Al Naabi, Rawan Y.
Abstract:: Scour is the main cause of bridge failures in the United States. Bridge failures raise a hazard to the safety of the traveling public as well as the massive economic consequences due to the high cost of constructing a new or a replacement bridge. The Oregon Department of Transportation (ODOT)...

Estimating the in situ Stratification via Remotely-sensed Internal Wave Speeds

Creator:: Fang, Chufan
Abstract:: This work investigates a methodology for estimating the ocean stratification gradient based on high-resolution, in space and time, remote sensing observations of internal wave propagation speeds. The internal wave speed observations were collected using a shore-based, X-band marine radar and the ocean vertical density profiles were collected simultaneously from an...

Prototyping of Thermoelectric Energy Harvesting Circuitry for IoT Devices

Creator:: Webb, Derek
Abstract:: Due to the advancement of incredibly low power microcontrollers and small form factor integrated circuits, energy harvesting can be considered as an alternative, low power source for remote ocean sensing and measurements. To demonstrate the effectiveness of harvesting thermoelectric energy contained in the temperature differential between ocean surface water and...

Design and Implementation of a Modular Ocean Drifter Kit

Creator:: Green, Austin
Abstract:: Ocean Drifters are a low-cost and easy-to-use platform that are commonly used for studying ocean currents. With added interest in studying the ocean, emphasis has been taken to make it more accessible. A pilot course focused on introducing the topic of ocean sensing was announced. The HC 407 course will...

Impacts of Environmentally Responsible Engineering (ERE) Concepts in a New First Year Engineering Program

Creator:: Smith, Madelyn
Abstract:: This full research paper explores two factors of increasing importance for first-year university engineering curricula: sustainability and diversity. Over the past fifteen years, many universities in the United States have adjusted their engineering programs in response to these two values expressed by industry, professional organizations, and the Accreditation Board for...

Large Wood Hydraulics: Using Structure-from-Motion to Estimate Flow Depths

Creator:: Tutka, Michal
Abstract:: Estimating how large instream wood (LW) may impact local hydraulics is critical both for mitigating flood hazards and for ensuring intended habitat benefits of the LW are produced. In practice, the design of forms such as LW is limited by a lack of mechanistic tools for estimating how LW features...

Evaluation of Stereoscopic Camera Systems for Non-Intrusive Spatial Free Surface Measurement in Coastal Research Laboratories

Creator:: O'Day, Christopher S.
Abstract:: Physical modelling is instrumental to the progression of coastal engineering research and our understanding of the offshore and nearshore environments. Scaled models are designed and built to be tested in coastal research laboratories, where a wave basin or flume generates the desired wave conditions for experimentation. The surrounding hydrodynamics of...

Shell Boring Polychaetes and the Oregon Oyster Aquaculture Industry: Spatial Distribution, Regulatory Actions, and Stakeholder Engagement

Creator:: Considine, Megan E.
Abstract:: Shell-boring polychaetes pose economic risks for oyster aquaculture industries as they reduce the aesthetic quality of oyster products by creating unsightly mud-filled blisters on the inside of the shell. Recently there has been a reported uptick in infested oysters on commercial farms along the west coast of the US, which...

Morphodynamic Evolution of Coastal Oregon: Using New Lidar-derived Beach and Sand Dune Morphometrics to Explore Multi-decadal Change

Creator:: Light, Jacob W
Abstract:: The coast of Oregon is highly dynamic, with beach and dune morphodynamics constantly evolving in response to physical and ecological forcing at scales ranging from seconds to decades and meters to tens of kilometers. Evaluating spatial and temporal trends in shoreline evolution is paramount in understanding and eventually developing a...
