CTD and velocity surveys of seaward jets off Northern California, July 1981 and 1982

Creator:: Kosro, P. Michael, 1951- and Huyer, Adriana, 1945-
Abstract:: Two mesoscale surveys were conducted (in July 1981 and July 1982) near Point Arena, California, to determine the structure and circulation associated with tongues of cold surface water extending seaward from the coastal zone. Both surveys were designed at sea on the basis of available satellite IR data, and each...

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...

Ocean data assimilation using optimal interpolation with a quasi-geostrophic model

Creator:: Rienecker, Michele M. and Miller, Robert N.
Abstract:: Optimal interpolation (OI) has been used to produce analyses of quasi-geostrophic (QG) stream function over a 59-day period in a 150-km-square domain off northern California. Hydrographic observations acquired over five surveys, each of about 6 days' duration, were assimilated into a QG open boundary ocean model. Since the true forecast...

Data assimilation and bathymetric inversion in a two‐dimensional horizontal surf zone model

Creator:: Wilson, G. W., Özkan-Haller, H. Tuba, and Holman, R. A.
Abstract:: A methodology is described for assimilating observations in a steady state twodimensional horizontal (2‐DH) model of nearshore hydrodynamics (waves and currents), using an ensemble‐based statistical estimator. In this application, we treat bathymetry as a model parameter, which is subject to a specified prior uncertainty. The statistical estimator uses state augmentation...

Seismic attribute inversion for velocity and attenuation structure using data from the GLIMPCE Lake Superior experiment

Creator:: Matheney, Michael P., Nowack, Robert L., and Tréhu, Anne Martine
Abstract:: A simultaneous inversion for velocity and attenuation structure using multiple seismic attributes has been applied to refraction data from the 1986 GLIMPCE Lake Superior experiment. The seismic attributes considered include envelope amplitude, instantaneous frequency, and travel time of first arrival data. Instantaneous frequency is converted to t* using a matching...

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 model-data comparison of gross primary productivity: Results from the North American Carbon Program site synthesis

Altaf, Barr, Alan, Chen, Jing M., Davis, Kenneth J., Dimitrov, Dimitre, Hilton, Timothy W., Hollinger, David Y., Humphreys, Elyn, Poulter, Benjamin, Raczka, Brett M., Richardson, Andrew D., Sahoo, Alok, Thornton, Peter, Vargas, Rodrigo, Verbeeck, Hans, Anderson, Ryan, Baker, Ian, Black, T.

Abstract:: Accurately simulating gross primary productivity (GPP) in terrestrial ecosystem models is critical because errors in simulated GPP propagate through the model to introduce additional errors in simulated biomass and other fluxes. We evaluated simulated, daily average GPP from 26 models against estimated GPP at 39 eddy covariance flux tower sites...

Evolution of the Gorda Escarpment, San Andreas fault and Mendocino triple junction from multichannel seismic data collected across the northern Vizcaino block, offshore northern California

Creator:: Godfrey, Nicola J., Meltzer, Anne S., Klemperer, Simon L., Tréhu, Anne Martine, Leitner, Beate, Clarke, Samuel H., and Ondrus, Amy
Abstract:: The Gorda Escarpment is a north facing scarp immediately south of the Mendocino transform fault (the Gorda/Juan de Fuca-Pacific plate boundary) between 126°W and the Mendocino triple junction. It elevates the seafloor at the northern edge of the Vizcaino block, part of the Pacific plate, ~1.5 km above the seafloor...

Variation in the position of the upwelling front on the Oregon shelf

Creator:: Austin, Jay A. and Barth, John A.
Abstract:: As part of an experiment to study wind-driven coastal circulation, 17 hydrographic surveys of the middle to inner shelf region off the coast of Newport, OR (44.65°N, from roughly the 90 m isobath to the 10 m isobath) were performed during Summer 1999 with a small, towed, undulating vehicle.

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.
