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...

Creator:: Thomas, A. C. and Strub, P. Ted
Abstract:: Previously published physical and biological data document a zonally oriented frontal region within the California Current system separating colder and more eutrophic water north of ≈33°N from warmer; more stratified, and oligotrophic water farther to the south. Satellite images of phytoplankton pigment from the coastal zone color scanner from 1979-1983...

Creator:: Thomas, A. C. and Strub, P. Ted
Abstract:: A 5-year time series of coastal zone color scanner imagery (1980-1983, 1986) is used to examine changes in the large-scale pattern of chlorophyll pigment concentration coincident with the spring transition in winds and currents along the west coast of North America. The data show strong interannual variability in the timing...

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...

Creator:: Kelly, Kathryn A. and Strub, P. Ted
Abstract:: Two methods of estimating surface velocity vectors from advanced very high resolution radiometer (AVHRR) data were applied to the same set of images and the results were compared with in situ and altimeter measurements. The first method used and automated feature –tracking algorithm and the second method used an inversion...

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:...

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...

Creator:: Thomas, A. C., Blanco, J. L., Carr, M. E., Strub, P. Ted, and Osses, J.
Abstract:: Time series of satellite measurements are used to describe patterns of surface temperature and chlorophyll associated with the 1996 cold La Nina phase and the 1997-1998 warm El Nino phase of the El Nino - Southern Oscillation cycle in the upwelling region off northern Chile. Surface temperature data are available...

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...

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...
