Energy and heat fluxes due to vertically propagating Yanai waves observed in the equatorial Indian Ocean

Creator:: Smyth, W. D., Durland, T. S., and Moum, J. N.
Abstract:: Shipboard current measurements in the equatorial Indian Ocean in October and November of 2011 revealed oscillations in the meridional velocity with amplitude ~0.10 m/s. These were clearest in a layer extending from ~300 to 600 m depth and had periods near 3 weeks. Phase propagation was upward. Measurements from two...

Climate change impacts on wave and surge processes in a Pacific Northwest (USA) estuary

Creator:: Cheng, T. K., Hill, D. F., Beamer, J., and García-Medina, G.
Abstract:: Total water levels (TWLs) within estuaries are influenced by tides, wind, offshore waves, and streamflow, all of which are uniquely affected by climate change. The magnitude of TWL associated with various return periods is relevant to understanding how the hydrodynamics of a bay or estuary may evolve under distinct climate...

Photosynthetic Characteristics and Estimated Growth Rates Indicate Grazing Is the Proximate Control of Primary Production in the Equatorial Pacific

Creator:: Cullen, John J., Lewis, Marlon R., Davis, Curtiss O., and Barber, Richard T.
Abstract:: Macronutrients persist in the surface layer of the equatorial Pacific Ocean because the production of phytoplankton is limited; the nature of this limitation has yet to be resolved. Measurements of photosynthesis as a function of irradiance (P-I) provide information on the control of primary productivity, a question of great biogeochemical...

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...

Observations of near-inertial waves in acoustic doppler current profiler measurements made during the mixed layer dynamics experiment

Creator:: Chereskin, T. K., Levine, Murray D., Harding, A. J., and Regier, L. A.
Abstract:: Measurements of upper ocean shear made during the Mixed Layer Dynamics Experiment (MILDEX) provide evidence of large horizontal scale motion at near‐inertial frequency. The measurements consist of shipboard acoustic Doppler current profiles. Four large‐scale spatial surveys of 2–4 days duration were made by the R/V Wecoma as a set of...

Formation and pathways of the intermediate water in the Parallel Ocean Circulation Model's Southern Ocean

Creator:: Schouten, Mathijs W. and Matano, Ricardo P.
Abstract:: The formation mechanisms and pathways of intermediate water in the Southern Ocean are analyzed from output of a high-resolution ocean general circulation model. Deep winter mixed layer formation in the Southern Ocean is diagnosed from the model results and is found to be mostly consistent with observations. Diapycnal water mass...

Forcing and variability of nonstationary rip currents

Creator:: Long, J. W. and Özkan-Haller, H. Tuba
Abstract:: urface wave transformation and the resulting nearshore circulation along a section of coast with strong alongshore bathymetric gradients outside the surf zone are modeled for a consecutive 4 week time period. The modeled hydrodynamics are compared to in situ measurements of waves and currents collected during the Nearshore Canyon Experiment...

Surf zone bathymetry and circulation predictions via data assimilation of remote sensing observations

Creator:: Wilson, G. W., Özkan-Haller, H. Tuba, Holman, R. A., Haller, M. C., Honegger, D. A., and Chickadel, C. C.
Abstract:: Bathymetry is a major factor in determining nearshore and surf zone wave transformation and currents, yet is often poorly known. This can lead to inaccuracy in numerical model predictions. Here bathymetry is estimated as an uncertain parameter in a data assimilation system, using the ensemble Kalman filter (EnKF). The system...

Biological production in the NE Pacific and its influence on air-sea CO2 flux: Evidence from dissolved oxygen isotopes and O2/Ar

Creator:: Juranek, L. W., Quay, P. D., Feely, R. A., Lockwood, D., Karl, D. M., and Church, M. J.
Abstract:: We determine rates of gross photosynthetic O₂ production (GOP) and net community O₂ production (NCP) using the triple oxygen isotope and O₂/Ar approach on two spring and two late summer meridional transects of the NE Pacific. Observed GOP and NCP in the subtropical (89 ± 9 and 8.3 ± 1.3...

Abstract:: We have applied a normalized difference algorithm to 8 day composite chlorophyll-a (CHL) and fluorescence line height (FLH) imagery obtained from the Moderate Resolution Imaging Spectroradiometer aboard the Aqua spacecraft in order to detect and monitor phytoplankton blooms in the Oregon coastal region. The resulting bloom products, termed CHL[subscript rel]...
