Explicit Planktic Calcifiers in the University of Victoria Earth System Climate Model, Version 2.9

Creator:: Kvale, K. F., Meissner, K. J., Keller, D. P., Eby, M., and Schmittner, A.
Abstract:: Marine calcifiers as a plankton functional type (PFT) are a crucial part of the global carbon cycle, being responsible for much of the carbon export to the deep ocean entering via biological pathways. Deep ocean carbon export through calcifiers is controlled by physiological, ecological and biogeochemical factors. This paper describes...

A global model of the marine ecosystem for long-term simulations: Sensitivity to ocean mixing, buoyancy forcing, particle sinking, and dissolved organic matter cycling

Creator:: Schmittner, Andreas, Oschlies, Andreas, Giraud, X., Eby, M., and Simmons, H. L.
Abstract:: A new model of the marine ecosystem coupled into a global Earth System Climate Model suitable for long-term (multimillennial timescale) simulations is presented. The model is based on nitrate as the sole limiting nutrient. Prognostic equations for nutrients, phytoplankton, zooplankton, and detritus are solved online in the three-dimensional ocean circulation...

Nonlinearity of carbon cycle feedbacks

Creator:: Zickfeld, Kirsten, Eby, Michael, Matthews, H. Damon, Schmittner, Andreas, and Weaver, Andrew J.
Abstract:: Coupled climate–carbon models have shown the potential for large feedbacks between climate change, atmospheric CO₂ concentrations, and global carbon sinks. Standard metrics of this feedback assume that the response of land and ocean carbon uptake to CO₂ (concentration–carbon cycle feedback) and climate change (climate–carbon cycle feedback) combine linearly. This study...

Simulating the global distribution of nitrogen isotopes in the ocean

Creator:: Somes, Christopher J., Schmittner, Andreas, Galbraith, Eric D., Lehmann, Moritz F., Altabet, Mark A., Montoya, Joseph P., Letelier, Ricardo M., Mix, Alan C., Bourbonnais, Annie, and Eby, Michael
Abstract:: We present a new nitrogen isotope model incorporated into the three-dimensional ocean component of a global Earth system climate model designed for millennial timescale simulations. The model includes prognostic tracers for the two stable nitrogen isotopes, 14N and 15N, in the nitrate (NO3−), phytoplankton, zooplankton, and detritus variables of the...

Effects of ocean acidification on the larvae of a high-value pelagic fisheries species, mahi-mahi Coryphaena hippurus

Creator:: Bignami, Sean, Sponaugle, Su, and Cowen, Robert K.
Abstract:: Negative impacts of CO₂-induced ocean acidification on marine organisms have proven to be variable both among and within taxa. For fishes, inconsistency confounds our ability to draw conclusions that apply across taxonomic groups and highlights the limitations of a nascent field with a narrow scope of study species. Here, we...

Effect of Nanophyetus salmincola and Bacterial Co-Infection on Mortality of Juvenile Chinook Salmon

Creator:: Roon, Sean R., Alexander, Julie D., Jacobson, Kym C., and Bartholomew, Jerri L.
Abstract:: The freshwater trematode Nanophyetus salmincola has been demonstrated to impair salmonid immune function and resistance to the marine pathogen Vibrio anguillarum, potentially resulting in ocean mortality. We examined whether infection by the parasite N. salmincola similarly increases mortality of juvenile Chinook Salmon Oncorhynchus tshawytscha when they are exposed to the...

Rapid Microwave Synthesis of the Iron Arsenides NdFeAsO and NdFe₀.₉Co₀.₁AsO

Creator:: Muir, Sean, Rachdi, Omar, and Subramanian, Mas
Abstract:: The future of iron pnictide superconductors in technology is still undecided. While these materials are now known to possess high critical temperatures and critical magnetic fields processing methods for these materials are still in their infancy. Recently we have been investigating possible ways to speed up the synthetic process for...

Rapid Microwave Synthesis of Indium Filled Skutterudites: An energy efficient route to high performance thermoelectric materials

Creator:: Biswas, Krishnendu, Muir, Sean, and Subramanian, Mas A.
Abstract:: Filled skutterudites are promising thermoelectric materials due to reduced thermal conductivity upon inserting a guest atom or 'rattler' into the CoSb₃ structure. By using an indium rattler dimensionless Figure of Merit (ZT) values > 1 at 650 K have been reported. The conventional synthesis of these compounds typically takes several...

The common neural parasite Pseudoloma neurophilia is associated with altered startle response habituation in adult zebrafish (Danio rerio): Implications for the zebrafish as a model organism

Creator:: Spagnoli, Sean, Xue, Lan, and Kent, Michael L.
Abstract:: The zebrafish’s potential as a model for human neurobehavioral research appears nearly limitless despite its relatively recent emergence as an experimental organism. Since the zebrafish has only been part of the research community for a handful of decades, pathogens from its commercial origins continue to plague laboratory stocks. One such...

Crystal structure beneath the central Oregon convergent margin from potential-field modeling: Evidence for a buried basement ridge in local contact with a seaward dipping backstop

Creator:: Fleming, Sean W. and Tréhu, Anne Martine
Abstract:: Models of magnetic and gravity anomalies along two E-W transects offshore central Oregon, one of which is coincident with a detailed velocity model, provide quantitative limits on the structure of the subducting oceanic crust and the crystalline backstop. The models indicate that the backstop-forming western edge of the Siletz terrane,...
