Oxygen production and carbon sequestration in an upwelling coastal margin

Creator:: Hales, Burke, Karp-Boss, Lee, Perlin, Alexander, and Wheeler, Patricia A.
Abstract:: We examined high-resolution cross-shelf distributions of particulate organic carbon (POC) and dissolved O₂ during the upwelling season off the Oregon coast. Oxygen concentrations were supersaturated in surface waters, and hypoxic in near-bottom waters, with greatly expanded hypoxic conditions late in the season. Simplified time-dependent mass balances on cross-shelf integrated concentrations...

Seasonal sea surface cooling in the equatorial Pacific cold tongue controlled by ocean mixing

Creator:: Moum, James N., Perlin, Alexander, Nash, Jonathan D., and McPhaden, Michael J.
Abstract:: Sea surface temperature (SST) is a critical control on the atmosphere(1), and numerical models of atmosphere-ocean circulation emphasize its accurate prediction. Yet many models demonstrate large, systematic biases in simulated SST in the equatorial 'cold tongues' (expansive regions of net heat uptake from the atmosphere) of the Atlantic(2) and Pacific(3)...

Evaluation of directly wind-coherent near-inertial surface currents off Oregon using a statistical parameterization and analytical and numerical models

Creator:: Kim, Sung Yong, Kosro, P. Michael, and Kurapov, Alexander L.
Abstract:: Directly wind-coherent near-inertial surface currents off the Oregon coast are investigated with a statistical parameterization of observations and outputs of a regional numerical ocean model and three one-dimensional analytical models including the slab layer, Ekman, and near-surface averaged Ekman models. The transfer functions and response functions, statistically estimated from observed...

Particle resuspension in the Columbia River plume near field

Creator:: Spahn, Emily Y., Homer-Devine, Alexander R., Nash, Jonathan, Jay, David A., and Kilcher, Levi
Abstract:: Measurements of suspended sediment concentration, velocity, salinity, and turbulent microscale shear in the near-field region of the Columbia River plume are used to investigate the mechanisms of sediment resuspension and entrainment into the plume. An east-west transect was occupied during spring and neap tide periods in August 2005 and May...

Assimilation of moored velocity data in a model of coastal wind-driven circulation off Oregon: Multivariate capabilities

Creator:: Kurapov, Alexander, Allen, John S., Egbert, Gary D., Miller, Robert N., Kosro, P. Michael, Levine, Murray D., and Barth, John A.
Abstract:: Horizontal current measurements from an array of moored acoustic Doppler profilers are assimilated sequentially into a model of coastal wind-driven circulation off Oregon during the upwelling season of May–August 2001. Model results are compared against independent moored and ship survey data to document a positive effect of velocity data assimilation...

A nested grid model of the Oregon Coastal Transition Zone: Simulations and comparisons with observations during the 2001 upwelling season

Creator:: Springer, S. R., Samelson, Roger M., Allen, John S., Egbert, Gary D., Kurapov, Alexander, Miller, Robert N., and Kindle, J. C.
Abstract:: The Oregon Coastal Transition Zone (OCTZ) extends several hundred kilometers offshore where shelf flows interact with the northern California Current. A primitive-equation numerical ocean model is used to study the upwelling circulation in this region from 1 May to 1 November 2001. This OCTZ model obtains initial and boundary conditions...

Modulation of Wind Work by Oceanic Current Interaction with the Atmosphere

Creator:: Renault, Lionel, Molemaker, M. Jeroen, McWilliams, James C., Shchepetkin, Alexander F., Lemarié, Florian, Chelton, Dudley, Illig, Serena, and Hall, Alex
Abstract:: In this study, uncoupled and coupled ocean–atmosphere simulations are carried out for the California Upwelling System to assess the dynamic ocean–atmosphere interactions, namely, the ocean surface current feedback to the atmosphere. The authors show the current feedback, by modulating the energy transfer from the atmosphere to the ocean, controls the...

Creator:: Toome, Merje, Ohm, Robin A., Riley, Robert W., Boyd, Alexander, Spatafora, Joseph W., and et al.
Abstract:: Mixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed the genome of M. osmundae, focusing on genes that may provide some insight into its mode of pathogenicity and reproductive biology. Mixia osmundae has the smallest plant pathogenic basidiomycete...

Internal solitary waves of elevation advancing on a shoaling shelf

Creator:: Klymak, Jody M. and Moum, James N.
Abstract:: A sequence of three internal solitary waves of elevation were observed propagating shoreward along a near-bottom density interface over Oregon’s continental shelf. These waves are highly turbulent and coincide with enhanced optical backscatter, consistent with increased suspended sediments in the bottom boundary layer. Nonlinear solitary wave solutions are employed to...
