The impact of wave energy converter arrays on wave-induced forcing in the surf zone

Creator:: O'Dea, Annika, Haller, Merrick C., and Ozkan-Haller, H. Tuba
Abstract:: An alternative metric for assessing nearshore hydrodynamic impact due to Wave Energy Converter (WEC) arrays is presented that is based on the modeled changes in alongshore radiation stress gradients in the lee of the array. The metric is developed using a previously observed relationship between measured radiation stresses and alongshore...

Mechanistic analysis of the wave-current interaction in the plume region of a partially mixed tidal inlet

Creator:: Moghimi, Saeed, Özkan-Haller, H. Tuba, Akan, Cigdem, and Jurisa, Joseph T.
Abstract:: In this research, a three-dimensional coupled wave-circulation model, including meteorological forcing, freshwater inflow and time varying open boundary conditions, for New River Inlet is validated. A mechanistic approach is taken to investigate how various wave-current interaction mechanisms affect the nearshore circulation, plume expansion and surface wave field in the plume...

Photohydrogen production from dark-fermented palm oil mill effluent (DPOME) and statistical optimization: Renewable substrate for hydrogen

Creator:: Mishra, Puranjan, Singh, Lakhveer, Ab Wahid, Zularisam, Krishnan, Santhana, Rana, Supriyanka, Islam, M. Amirul, Sakinah, Mimi, Ameen, Fuad, and Syed, A.
Abstract:: Biological hydrogen production through photo-fermentative process using dark fermented palm oil effluent (DPOME) is a cost effective and environmentally benign process. In this study, effect of various factors like light intensity, agitation rate and dilution of DPOME on the hydrogen productivity of Rhodopseudomanas palustris were investigated using batch system. Investigation...

PacWave Wave Resource Assessment

Creator:: Dunkle, Gabrielle, Robertson, Bryson, Garcia-Medina, Gabriel, and Yang, Zhaoqing
Abstract:: The Pacific Northwest of the United States is characterized by one of the greatest annual mean wave power resources in the world. As a result, the wave energy resource offshore of Oregon has been characterized, through hindcast models and physical buoy data, throughout the past decade. Over the past 8...

Metabolomic Analysis of Oregon Coast Sediment Pore Waters using Ultrahigh Resolution Mass Spectrometry

Creator:: Merlo, James B.
Abstract:: One of the principal drivers of climate change is the concentration of greenhouse gases such as CO2 in the atmosphere. A large portion of this CO2 ends up in the waters off the continental coasts where it transforms into biomass. The major sink for this matter is the ocean sediments...

The effects of changing climate on estuarine water levels: a United States Pacific Northwest case study

Creator:: Parker, Kai, Hill, David, García-Medina, Gabriel, and Beamer, Jordan
Abstract:: Climate change impacts on extreme water levels (WLs) at two United States Pacific Northwest estuaries are investigated using a multicomponent process-based modeling framework. The integrated impact of climate change on estuarine forcing is considered using a series of sub-models that track changes to oceanic, atmospheric, and hydrologic controls on hydrodynamics....

The Power of Three: Coral Reefs, Seagrasses and Mangroves Protect Coastal Regions and Increase Their Resilience

Creator:: Guannel, Greg, Arkema, Katie, Ruggiero, Peter, and Verutes, Gregory
Abstract:: Natural habitats have the ability to protect coastal communities against the impacts of waves and storms, yet it is unclear how different habitats complement each other to reduce those impacts. Here, we investigate the individual and combined coastal protection services supplied by live corals on reefs, seagrass meadows, and mangrove...

Cooperative effects of pre-harvest calcium and gibberellic acid on tissue calcium content, quality attributes, and in relation to postharvest disorders of late-maturing sweet cherry

Creator:: Dong, Yu, Zhi, Huanhuan, and Wang, Yan
Abstract:: Six Ca(NO3)(2) sprays at 0.3% and 0.6% from pit hardening (PH) to 1 week before harvest (1WBH) most effectively increased Ca uptake in sweet cherry (Prunus avium). Low concentration (< 0.3%) did not affect the absorption of Ca; high concentration (> 1.6%) caused burning of leaf margins. Fruit treated with...

Quantifying Bulk Electrode Strain and Material Displacement within Lithium Batteries via High-Speed Operando Tomography and Digital Volume Correlation

Creator:: Finegan, Donal P., Tudisco, Erika, Scheel, Mario, Robinson, James B., Taiwo, Oluwadamilola O., Eastwood, David S., Lee, Peter D., Di Michiel, Marco, Bay, Brian, Hall, Stephen A., Hinds, Gareth, Brett, Dan J. L., and Shearing, Paul R.
Abstract:: Tracking the dynamic morphology of active materials during operation of lithium batteries is essential for identifying causes of performance loss. Digital volume correlation (DVC) is applied to high-speed operando synchrotron X-ray computed tomography of a commercial Li/MnO₂ primary battery during discharge. Real-time electrode material displacement is captured in 3D allowing...

Trade-offs in ecosystem impacts from nanomaterial versus organic chemical ultraviolet filters in sunscreens

Creator:: Hanigan, David, Truong, Lisa, Schoepf, Jared, Nosaka, Takayuki, Mulchandani, Anjali, Tanguay, Robert L., and Westerhoff, Paul
Abstract:: Both nanoparticulate (nZnO and nTiO(2)) and organic chemical ultraviolet (UV) filters are active ingredients in sunscreen and protect against skin cancer, but limited research exists on the environmental effects of sunscreen release into aquatic systems. To examine the trade-offs of incorporating nano particles (NPs) into sunscreens over the past two...
