Integrating traceability with onboard handling to enhance product quality and marketability of Eastern Pacific troll-caught albacore tuna (Thunnus alalunga)

Creator:: Thompson, Michael J.
Abstract:: The fishing industry in the Pacific Northwest is a dynamic and highly competitive industry that must constantly respond to rapidly changing resource, regulatory and market forces. These forces have already had a significant impact on our fisheries and will continue to do so as we learn more about the biology...

Coastal Wind-Driven Circulation in the Vicinity of a Bank. Part II: Modeling Flow over the Heceta Bank Complex on the Oregon Coast

Creator:: Whitney, Michael M. and Allen, J. S.
Abstract:: This study investigates wind-driven circulation in the vicinity of the Heceta Bank complex along the Oregon shelf. Numerical experiments forced with steady winds (0.1 Pa) are conducted; upwelling and downwelling cases are compared. The asymmetric bank bathymetry is the only configurational difference from the symmetric bank runs analyzed in Part...

Coastal Wind-Driven Circulation in the Vicinity of a Bank. Part I: Modeling Flow over Idealized Symmetric Banks

Creator:: Whitney, Michael M. and Allen, J. S.
Abstract:: This study examines how coastal banks influence wind-driven circulation along stratified continental shelves. Numerical experiments are conducted for idealized symmetric banks; the standard bank (200 km long and 50 km wide) has dimensions similar to the Heceta Bank complex along the Oregon shelf. Model runs are forced with 10 days...

Oceanic phosphorus imbalance : magnitude of the mid-ocean ridge flank hydrothermal sink

Creator:: Wheat, C. Geoffrey, McManus, James, Mottl, Michael J., and Giambalvo, Emily
Abstract:: We present a new estimate for the crustal phosphorous sink that results from reactions among seawater, basalt, and sediment blanketing low temperature mid-ocean ridge flank hydrothermal systems. New estimates for global hydrothermal power output, sediment thickness, and the dissolved phosphate concentrations in basement formation fluids indicate that fluid flow through...

Potential for non-destructive astrochemistry using the ExoMars PanCam

Creator:: Storrie-Lombardi, Michael C., Muller, J.-P., Fisk, Martin R., Griffiths, A. D., and Coates, A. J.
Abstract:: We investigate the utility of adding a 365 nm ultraviolet (UV) light source to the ExoMars panoramic camera (PanCam) scheduled for launch in 2013. The modification makes it feasible to monitor rover drill cuttings for aromatic organic molecules and provide constraints on polycyclic aromatic hydrocarbons (PAH) as a function of...

Possible emplacement of crustal rocks into the forearc mantle of the Cascadia Subduction Zone

Creator:: Calvert, Andrew J., Fisher, Michael A., Ramachandran, Kumar, and Tréhu, Anne Martine
Abstract:: Seismic reflection profiles shot across the Cascadia forearc show that a 5–15 km thick band of reflections, previously interpreted as a lower crustal shear zone above the subducting Juan de Fuca plate, extends into the upper mantle of the North American plate, reaching depths of at least 50 km. In...

Satellite Microwave SST Observations of Transequatorial Tropical Instability Waves

Creator:: Chelton, Dudley B., Wentz, Frank J., Genremann, Chelle L., de Szoeke, Roland A., and Schlax, Michael G.
Abstract:: Satellite measurements of sea-surface temperature (SST) by the TRMM Microwave Imager reveal previously unreported features of tropical instability waves (TIWs). In the Pacific, TIW-related variability is observed from the eastern boundary to at least 160°E. Cusp-shaped distortions of SST fronts and associated trains of anticyclonic vortices both north and south...

Changes in equatorial Pacific thermocline depth in response to Panamanian seaway closure: Insights from a multi-model study

Creator:: Zhang, Xiao, Prange, Matthias, Steph, Silke, Butzin, Martin, Krebs, Uta, Lunt, Daniel J., Nisancioglu, Kerim H., Park, Wonsun, Schmittner, Andreas, Schneider, Birgit, and Schulz, Michael
Abstract:: The early Pliocene warm phase was characterized by high sea surface temperatures and a deep thermocline in the eastern equatorial Pacific. A new hypothesis suggests that the progressive closure of the Panamanian seaway contributed substantially to the termination of this zonally symmetric state in the equatorial Pacific. According to this...

Optical scattering and backscattering by organic and inorganic particulates in U.S. coastal waters

Creator:: Snyder, William A., Arnone, Robert A., Davis, Curtiss O., Goode, Wesley, Gould, Richard W., Ladner, Sherwin, Lamela, Gia, Rhea, William J., Stavn, Robert, Sydor, Michael, and Weidemann, Allen
Abstract:: We present the results of a study of optical scattering and backscattering of particulates for three coastal sites that represent a wide range of optical properties that are found in U.S. near-shore waters. The 6000 scattering and backscattering spectra collected for this study can be well approximated by a power-law...

Spectral particulate attenuation and particle size distribution in the bottom boundary layer of a continental shelf

Creator:: Boss, Emmanuel, Pegau, W. Scott, Gardner, Wilford D., Zaneveld, J. Ronald, Barnard, Andrew H., Twardowski, Michael S., Chang, G. C., and Dickey, T. D.
Abstract:: Spectral attenuation and absorption coefficients of particulate matter and collocated hydrographic measurements were obtained in the Mid-Atlantic Bight during the fall of 1996 and the spring of 1997 as part of the Coastal Mixing and Optics experiment. Within the bottom boundary layer (BBL) the magnitude of the beam attenuation decreased...
