Modeling Eddy Correlation Biases Created by Velocity Sensitivities of Clark-type Oxygen Microelectrodes Under Waves

Creator:: Albright, Andrea and Albright, Andrea T. P.
Abstract:: Field deployments, flume experiments, and a 2D wave model have been used to identify the characteristics of Clark-type oxygen microelectrodes and measurement parameters that could possibly bias eddy correlation (EC) flux measurements made under waves. Eddy correlation is a technique adapted from atmospheric sciences that couples concurrent and co-located velocity...

Spatiotemporal Variability in Benthic-Pelagic Coupling on the Oregon-Washington Shelf: An Investigation of Bottom Water and Benthic Flux Data

Creator:: Hughes, Anna R.
Abstract:: Continental shelf sediments are sinks for dissolved oxygen and sources of many major and minor nutrients required for oceanic surface primary production, resulting in a strong coupling between benthic and pelagic biogeochemical cycling. However, the influence and spatiotemporal variability of benthic remineralization on bottom-water chemistry and the supply of nutrients...

Investigating rotating microelectrodes for rapid in situ detection of oxygen

Creator:: Chace, Peter J.
Abstract:: Rotating disc electrodes (RDEs) exploit the induced flushing of a radially spun electrode to increase the overall rate of analyte flux to an electrode sensing surface and its resulting signal current (i). Here initial efforts to evaluate a rotating platinum (Pt) microelectrode for efficacy as a rapid in situ dissolved...

Evaluating Drivers of Iron Cycling in Oregon Continental Margin Sediments Using an Early Diagenetic Model

Creator:: Chan, Adrienne B.
Abstract:: Continental margin sediments have been recognized as a major source of dissolved iron to the global ocean. The focus of this study was to build an early diagenetic model that can be used to simulate iron fluxes from continental margins and thereby identify key controlling factors. The model uses the...

Novel Copper and Iron Complexes along the Oregon Coastal Upwelling Margin

Creator:: Bright, Peter, W.
Abstract:: Copper and iron are essential micronutrients that are required by marine primary producers for a variety of metabolic processes. Over 99% of both copper and iron are bound within organic complexes in the marine environment, however the molecular identity of many of these complexes remains unknown. The speciation of these...

Application of transport-reaction modeling to constrain biogeochemical processes in marine sediments

Creator:: Hong, Wei-Li
Abstract:: Quantifying the mass transport through marine sediments, and the geochemical response to such flow with numerical models has become a common and powerful approach for geochemical data interpretation. In this dissertation, I developed and applied transport-reaction models to unravel complex and interdependent reactions involving carbon, sulfur and silica transformations in...

The First Spatiotemporal Estimation of Future Vent Opening at Harrat Khaybar, Saudi Arabia

Creator:: Alohali, Abdullah W.
Abstract:: The 180,000 km² of Arabian lava fields (“harrats” in Arabic) form one of the largest distributed basaltic provinces in the world. Approximately 50% of these are located in Saudi Arabia. The most recent eruption in 1256 AD, as well as seismicity and ground deformation associated with shallow dike emplacement in...

Bridging Data and Theory: Developing Physics Informed Machine Learning for Snow Hydrology

Creator:: Steele, Hannah
Abstract:: Snow is a critical component of global climate regulation and provides water resources to over one billion people worldwide. Yet current measurement methods and modeling techniques lack the ability to fully capture snow characteristics such as snow water equivalent (SWE), snow depth, and density variable landscapes. In recent years, the...

Carbonates dissolution and precipitation in hemipelagic sediments overlaid by supersaturated bottom-waters - Gulf of Aqaba, Red Sea

Creator:: Steiner, Zvi, Lazar, Boaz, Reimers, Clare E., and Erez, Jonathan
Abstract:: Whether CaCO₃ dissolves within the top centimeters of marine sediments overlaid by deep, supersaturated bottom waters remains an area of debate in geochemistry. This uncertainty stems from the fact that different methods used to assess CaCO₃ dissolution rates often provide what appear to be profoundly different results. Here we combine...

Technical note: Time lag correction of aquatic eddy covariance data measured in the presence of waves

Creator:: Berg, P., Reimers, Clare E., Rosman, J. H., Huettel, M., Delgard, M. L., Reidenbach, M. A., and Özkan-Haller, H. Tuba
Abstract:: Extracting benthic oxygen fluxes from eddy covariance time series measured in the presence of surface gravity waves requires careful consideration of the temporal alignment of the vertical velocity and the oxygen concentration. Using a model based on linear wave theory and measured eddy covariance data, we show that a substantial...
