Large-scale structure of the spring transition in the coastal ocean off western North America

Creator:: Strub, P. Ted, Allen, John S., Huyer, Adriana, 1945-, and Smith, Robert L. (Robert Lloyd), 1935-
Abstract:: Past measurements off the coast of central Oregon and Washington have shown that the rapid change from northward monthly mean winter winds to southward summer winds forces a "spring transition" of the coastal ocean: sea levels and temperatures drop, and mean surface currents shift from northward to southward. Current and...

Seasonal cycles of currents, temperatures, winds, and sea level over the northeast pacific continental shelf: 35°N to 48°N

Creator:: Strub, P. Ted, Allen, John S., Huyer, Adriana, 1945-, Smith, Robert L. (Robert Lloyd), 1935-, and Beardsley, R. C.
Abstract:: Seasonal cycles of coastal wind stress, adjusted sea level (ASL), shelf currents, and water temperatures off the west coast of North America (35°N to 48°N) are estimated by fitting annual and semiannual harmonics to data from 1981-1983. Longer records (9-34 years) of monthly ASL indicate that these two harmonics adequately...

Seasonal climatology of hydrographic conditions in the upwelling region off northern Chile

Creator:: Blanco, J. L., Thomas, A. C., Carr, M.-E., and Strub, P. Ted
Abstract:: Over 30 years of hydrographic data from the northern Chile (18°S-24°S) upwelling region are used to calculate the surface and subsurface seasonal climatology extending 400 km offshore. The data are interpolated to a grid with sufficient spatial resolution to preserve crossshelf gradients and then presented as means within four seasons:...

The nature of the cold filaments in the California current system

Creator:: Strub, P. Ted, Kosro, P. Michael, 1951-, Huyer, Adriana, 1945-, Brink, K. H., Hayward, T., Niiler, Pearn P., James, C., Dewey, R., Walstad, L., Chavez, F., Ramp, S., Mackas, D. L., Swenson, M., Washburn, L. A., Barth, John A., Hood, R. R., Abbott, Mark R., Kadko, D., Barber, R., Haidvogel, D., Batteen, M., and Haney, R.
Abstract:: Data from the Coastal Transition Zone (CTZ) experiment are used to describe the velocity fields and water properties associate with cold filaments in the California Current. Combined with previous field surveys and satellite imagery, these show seasonal variability with maximum dynamic height ranges and velocities in summer and minimum values...

Hydrographic conditions off northern Chile during the 1996–1998 La Nina and El Nino events

Creator:: Blanco, Jose Luis, Carr, Mary-Elena, Thomas, Andrew C., and Strub, P. Ted
Abstract:: The evolution of oceanographic conditions in the upwelling region off northern Chile (18°–24°S) between 1996 and 1998 (including the 1997–1998 El Niño) is presented using hydrographic measurements acquired on quarterly cruises of the Chilean Fisheries Institute, with sea surface temperature (SST), sea level, and wind speeds from Arica (18.5°S), Iquique...

Estimates of sea surface height and near-surface alongshore coastal currents from combinations of altimeters and tide gauges

Creator:: Saraceno, M., Strub, P. Ted, and Kosro, P. Michael, 1951-
Abstract:: Present methods used to retrieve altimeter data do not provide reliable estimates of sea surface height (SSH) in the nearshore region, resulting in a measurement gap of 25–50 km next to the coast. In the present work, gridded SSH fields produced by Archiving, Validation, and Interpretation of Satellite Oceanographic data...

Dynamical analysis of the upwelling circulation off central Chile

Creator:: Mesias, Jorge M., Matano, Ricardo P., and Strub, P. Ted
Abstract:: In this article we analyze the momentum and vorticity balances of a numerical simulation of the upwelling circulation off central Chile (34° –40°S) and its response to interannual local wind changes. Our analysis indicates that the path of the upwelling jet is strongly controlled by the bottom topography. This topographic...

Spatial and interannual variability in mesoscale circulation in the northern California Current System

Creator:: Keister, Julie Eileen and Strub, P. Ted
Abstract:: We used wavelet analyses of sea surface height (SSH) from >13 years of satellite altimeter data to characterize the variability in mesoscale circulation in the northern California Current (35°N–49°N) and explore the mechanisms of variability. We defined ‘‘mesoscale’’ circulation as features, such as eddies and filaments, which have 50- to...

Wind-driven surface transport in stratified closed basins: Direct versus residual circulations

Creator:: Strub, P. Ted and Powell, Thomas M.
Abstract:: A numerical model has been used to investigate the wind-driven circulation in a stratified basin of moderate size, Lake Tahoe, California-Nevada. Two types of circulation are identified: "direct" circulations, in which the current directions remain relatively constant and the mean circulation formed over several days resembles the instantaneous circulation, and...

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...
