Tillamook volcanic series : further evidence for tectonic rotation of the Oregon Coast Range

Creator:: Magill, James, Cox, Allan, and Duncan, Robert A.
Abstract:: Paleomagnetic directions from the Eocene Tillamook Volcanic Series of the Oregon Coast Range point 460 clockwise from the expected Eocene field direction. Potassium argon dating of six dikes and flows from this formation yields a mean age of 44.3 ± 0.6 m.y. These results establish that the Oregon coastal block...

An arc tangent model of irradiance in the sea

Creator:: Zaneveld, J. Ronald and Spinrad, Richard W.
Abstract:: The solar energy flux as a function of depth (the irradiance profile) in the ocean is an important function. It influences the dynamics of the mixed layer via the heat budget as well as the biology of the euphotic zone. The following three-parameter model can take into account the very...

Heat and salt balances over the northern California shelf in winter and spring

Creator:: Dever, Edward P. and Lentz, S. J.
Abstract:: Heat and salt balances are estimated over the northern California shelf from early December 1988 through late February 1989 (winter) and from early March through early May 1989 (spring) from moored meteorological and oceanographic time series taken in 93 m of water 6.3 km from the coast. We find a...

Crustal wedging triggering recent deformation in the Andean thrust front between 31°S and 33°S: Sierras Pampeanas-Precordillera interaction

Creator:: Verges, J., Ramos, V. A., Meigs, A., Cristallini, E., Bettini, F. H., and Cortes, J. M.
Abstract:: We document a new model of crustal structure of the Andean front in Argentina where numerous historic earthquakes destroyed the cities of Mendoza in 1861 (M[subscript s] = ~7) and San Juan in 1944 (M[subscript w] = 7.0). The Cerro Salinas anticline is formed above the west directed Cerro Salinas...

Atmospheric response to solar radiation absorbed by phytoplankton

Creator:: Shell, K. M., Frouin, R., Nakamoto, S., and Somerville, R. C. J.
Abstract:: Phytoplankton alter the absorption of solar radiation, affecting upper ocean temperature and circulation. These changes, in turn, influence the atmosphere through modification of the sea surface temperature (SST). To investigate the effects of the present-day phytoplankton concentration on the atmosphere, an atmospheric general circulation model was forced by SST changes...

Near-surface trajectories off central and southern California

Creator:: Winant, C. D., Alden, D. J., Dever, Edward P., Edwards, K. A., and Hendershott, M. C.
Abstract:: The near-surface circulation in the Santa Barbara Channel and off the coast of central and southern California is described based on 20 releases of drifters drogued 1 m beneath the surface from 12 sites within the channel at bimonthly intervals. This description includes small-scale features of the circulation which are...

Effects of mesoscale processes on phytoplankton chlorophyll off Baja California

Creator:: T. Leticia Espinosa-Carreon, T. Leticia, Gaxiola-Castro, Gilberto, Beier, Emilio, Strub, P. Ted, and Kurczyn, J. A.
Abstract:: Using satellite sea surface height (SSH) and chlorophyll (CHL), the year 2000 is analyzed to characterize the effects of mesoscale circulation patterns on phytoplankton spatial variability in the California Current (CC) off Baja California. Satellite data are combined with and compared to in situ field measurements (chlorophyll-a and hydrographic variables)...

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...

Satellite-derived variability in chlorophyll, wind stress, sea surface height, and temperature in the northern California Current System

Creator:: Venegas, Roberto M., Strub, P. Ted, Beier, Emilio, Letelier, Ricardo M., Thomas, Andrew C., Cowles, Timothy J., James, Corinne, Soto-Mardones, Luis, and Cabrera, Carlos
Abstract:: Satellite-derived data provide the temporal means and seasonal and nonseasonal variability of four physical and biological parameters off Oregon and Washington (41°–48.5°N). Eight years of data (1998–2005) are available for surface chlorophyll concentrations, sea surface temperature (SST), and sea surface height, while six years of data (2000–2005) are available for...

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.
