Assimilation of surface velocity data into a primitive equation coastal ocean model

Creator:: Oke, Peter R., Allen, John S., Miller, Robert N., Egbert, Gary D., and Kosro, P. Michael, 1951-
Abstract:: A data assimilation system (DAS) of the wind‐driven, mesoscale shelf circulation off the Oregon coast is developed. The DAS assimilates low‐pass filtered surface velocity measurements, obtained from land‐based high‐frequency coastal radar arrays, into a primitive equation coastal ocean model using a sequential optimal interpolation scheme. Inhomogeneous and anisotropic estimates of...

Tidal currents on the central Oregon shelf : models, data, and assimilation

Creator:: Erofeeva, Svetlana Y., Egbert, Gary D., and Kosro, P. Michael, 1951-
Abstract:: Measurements of tidal currents on the central Oregon shelf are available from several sources, including recent high frequency (HF) coastal radar and Acoustic Doppler Profiler (ADP) deployments, and historical current moorings. In this paper we use a generalized inverse (GI) approach to compare these data to, and then assimilate them...

Secondary circulation associated with a shelfbreak front

Creator:: Barth, John A., Bogucki, Darek, Pierce, Stephen D., and Kosro, P. Michael, 1951-
Abstract:: Evidence for secondary circulation associated with a shelfbreak front is obtained from a high‐resolution, cross‐shelf section of hydrographic, optical and velocity fields. Convergence in the bottom boundary layer on the inshore side of the front and subsequent upwelling into the interior is evident by a mid‐water region of suspended bottom...

Horizontal transport and the distribution of nutrients in the coastal transition zone off Northern California: effects on primary production, phytoplankton biomass and species composition

Creator:: Chavez, Francisco P., Barber, Richard T., Kosro, P. Michael, 1951-, Huyer, Adriana, 1945-, Ramp, Steven R., Stanton, Timothy P., and Rojas de Mendiola, Blanca
Abstract:: Conductivity‐temperature‐depth surveys during 1988 encountered strong baroclinic jets that were evident in acoustic Doppler current profiler and hydrographic data. During June and July 1988 a filament with high surface nitrate, high chlorophyll, abundant populations of neritic centric diatoms, and higher rates of primary production was evident perpendicular to the coast...

Estimation of surface winds from upward looking acoustic doppler current profilers

Creator:: Brown, J., Barton, E.D., Trasvina, A., Velez, H.S., Kosro, P. Michael, 1951-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: Three upward looking acoustic Doppler current profilers (ADCP) were deployed beneath meteorological buoys in the Gulf of Tehuantepec, Mexico, during winter 1988-1989. Hourly averaged wind speed data from the buoys and from ship when in the vicinity were compared with surface acoustic backscatter intensity recorded at the ADCPs. The backscatter...

Structure of the coastal current field off Northern California during the coastal ocean dynamics experiment

Creator:: Kosro, P. Michael, 1951-
Abstract:: For 74 days during the spring and summer upwelling seasons of 1981 and 1982, in conjunction with the Coastal Ocean Dynamics Experiment, profiles of upper ocean currents were collected in the waters over the shelf and slope off northern California using a shipboard Doppler acoustic log. These measurements provide detailed...

Offshore wind forcing in the Gulf of Tehuantepec, Mexico: the asymmetric circulation

Creator:: Trasviña, A., Barton, E.D., Brown, J., Velez, H.S., Kosro, P. Michael, 1951-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: Since the early surveys carried out by the Eastern Tropical Pacific (EASTROPIC) and Scripps Tuna Oceanographic Research (STOR) projects in the tropical Pacific off Mexico, the northerly winds which blow over the Gulf of Tehuantepec were described as an Important factor controlling the dynamics of this coastal ocean. In January-February...

Mesoscale surveys over the shelf and slope in the upwelling region near Point Arena, California

Creator:: Huyer, Adriana, 1945- and Kosro, P. Michael, 1951-
Abstract:: Repeated mesoscale surveys of a 40-km-wide, 100-km-long, coastal region near Point Arena, California, were conducted during the upwelling season (April-August) in 1981 and 1982. Each survey included conventional conductivity-temperature-depth casts at standard locations over the continental shelf and slope between 38°N and 39°10'N, and continuous operation of a Doppler acoustic...

Currents and water masses of the coastal transition zone off Northern California, June to August 1988

Abstract:: In summer 1988, we made repeated mesoscale surveys of a grid extending 200 km offshore between 37°N and 39°N in the coastal transition zone off northern California, obtaining continuous acoustic Doppler current profiler data and conductivity-temperature-depth data at standard stations 25 km apart on alongshore sections 40 km apart. All...

Spatial and temporal characteristics of the mesoscale circulation of the California Current from eddy-resolving moored and shipboard measurements

Abstract:: Moored observations of currents and temperatures made in the upper 600 m on eddy-resolving scales over a 2-year period are used to examine the spatial and temporal characteristics of the California Current mesoscale circulation. The observations were made at three principal longitudes: 124°W, 126°W, and 128°W in the vicinity of...
