Seasonal Cross-Shelf Flow Structure, Upwelling Relaxation, and the Alongshelf Pressure Gradient in the Northern California Current System

Creator:: McCabe, Ryan M., Hickey, Barbara M., Dever, Edward P., and MacCready, Parker
Abstract:: Moored observations are used to investigate the seasonal change in vertical structure of the cross-shelf circulation at a midshelf location in the northern California Current System. A streamwise–normal coordinate system is employed to eliminate meander- and eddy-induced biases in the cross-shelf flow that are unaccounted for with an alternative, commonly...

Anomalous Near-Surface Low-Salinity Pulses off the Central Oregon Coast

Creator:: Mazzini, Piero L. F., Risien, Craig M., Barth, John A., Pierce, Stephen D., Erofeev, Anatoli, Dever, Edward P., Kosro, P. Michael, Levine, Murray D., Shearman, R. Kipp, and Vardaro, Michael F.
Abstract:: From mid-May to August 2011, extreme runoff in the Columbia River ranged from 14,000 to over 17,000 m³/s, more than two standard deviations above the mean for this period. The extreme runoff was the direct result of both melting of anomalously high snowpack and rainfall associated with the 2010–2011 La Niña....

River influences on shelf ecosystems: Introduction and synthesis

Creator:: Hickey, B. M., Kudela, R. M., Nash, Jonathan, Bruland, K. W., Peterson, W. T., MacCready, P., Lessard, E. J., Jay, D. A., Banas, N. S., Baptista, A. M., Dever, Edward P., Kosro, P. Michael, Kilcher, L. K., Homer-Devine, A. R., Zaron, E. D., McCabe, R. M., Peterson, J. O., Orton, P. M., Pan, J., and Lohan, M. C.
Abstract:: River Influences on Shelf Ecosystems (RISE) is the first comprehensive interdisciplinary study of the rates and dynamics governing the mixing of river and coastal waters in an eastern boundary current system, as well as the effects of the resultant plume on phytoplankton standing stocks, growth and grazing rates, and community...

Multiple trophic levels fueled by recirculation in the Columbia River plume

Creator:: Kudela, Raphael M., Horner-Devine, Alexander R., Banas, Neil S., Hickey, Barbara M., Peterson, Tawnya D., McCabe, Ryan M., Lessard, Evelyn J., Frame, Elizabeth, Bruland, Kenneth W., Jay, David A., Peterson, Jay O., Peterson, William T., Kosro, P. Michael, Palacios, Sherry L., Lohan, Maeve C., and Dever, Edward P.
Abstract:: Large rivers represent gateways for the transport of terrigenous and anthropogenic material to the coastal ocean. Here we document a ∼700 km2 recirculation or bulge associated with the Columbia River plume that retains recently discharged river water sufficiently to create a regional bioreactor. Fueled by a fluvial nitrate source, this...

Metabolism of Nonesterified and Esterified Hydroxycinnamic Acids in Red Wines by Brettanomyces bruxellensis

Creator:: Schopp, Lauren M., Lee, Jungmin, Osborne, James P., Chescheir, Stuart C., and Edwards, Charles G.
Abstract:: While Brettanomyces can metabolize nonesterified hydroxycinnamic acids found in grape musts/wines (caffeic, p-coumaric, and ferulic acids), it was not known whether this yeast could utilize the corresponding tartaric acid esters (caftaric, p-coutaric, and fertaric acids, respectively). Red wines from Washington and Oregon were inoculated with B. bruxellensis, while hydroxycinnamic acids...

Hydrothermal Discharge During Submarine Eruptions

Creator:: Baker, Edward T., Chadwick, Wi l l iam W. Jr., Cowen, James P., Dziak, Robert P., Rubin, Kenneth H., and Fornari, Daniel J.
Abstract:: Submarine volcanic eruptions and intrusions construct new oceanic crust and build long chains of volcanic islands and vast submarine plateaus. Magmatic events are a primary agent for the transfer of heat, chemicals, and even microbes from the crust to the ocean, but the processes that control these transfers are poorly...

Fishery-specific solutions to seabird bycatch in the U.S. West Coast sablefish fishery

Creator:: Good, Thomas P., Jannot, Jason E., Melvin, Edward F., Gladics, Amanda J., Suryan, Robert M., and Guy, Troy J.
Abstract:: Bird scaring lines (BSLs) protect longline fishing gear from seabird attacks, save bait, reduce incidental seabird mortality and are the most commonly prescribed seabird bycatch mitigation measure worldwide. We collaborated with fishermen to assess the efficacy of applying BSL regulations from the demersal longline sablefish fishery in Alaska to a...

In situ cosmogenic radiocarbon production and 2-D ice flow line modeling for an Antarctic blue ice area

Creator:: Buizert, Christo, Petrenko, Vasilii V., Kavanaugh, Jeffrey L., Cuffey, Kurt M., Lifton, Nathaniel A., Brook, Edward J., and Severinghaus, Jeffrey P.
Abstract:: Radiocarbon measurements at ice margin sites and blue ice areas can potentially be used for ice dating, ablation rate estimates and paleoclimatic reconstructions. Part of the measured signal comes from in situ cosmogenic ¹⁴C production in ice, and this component must be well understood before useful information can be extracted...

Radiometric ⁸¹Kr dating identifies 120,000-year-old ice at Taylor Glacier, Antarctica

Creator:: Buizert, Christo, Baggenstos, Daniel, Jiang, Wei, Purtschert, Roland, Petrenko, Vasilii V., Lu, Zheng-Tian, Mueller, Peter, Lee, James, Severinghaus, Jeffrey P., and Brook, Edward J.
Abstract:: We present the first successful ⁸¹Kr-Kr radiometric dating of ancient polar ice. Krypton was extracted from the air bubbles in four ~350 kg polar ice samples from Taylor Glacier in the McMurdo Dry Valleys, Antarctica, and dated using Atom Trap Trace Analysis (ATTA). The ⁸¹Kr radiometric ages agree with independent...
