SeaSoar observations during the GLOBEC NEP California Current survey IV (R0208) : 31 July - 19 August 2002

Creator:: O'Malley, Robert T. and Barth, John A.
Abstract:: As part of the GLOBEC NEP collaborative research project on the California Current (CC), this was the second of two cruises in 2002 to study the physical and biological oceanographic distributions and processes that influence juvenile salmonid habitat along the Oregon and northern California coast. The 2002 cruises followed similar...

Sea surface height and geostrophic velocity variability in the California current system as observed from the TOPEX altimeter

Creator:: Righi, Dylan D.
Abstract:: Eight years (1994-2000) of data from the TOPEX/Poseidon satellite altimeter are used to investigate the variability of the sea surface height and geostrophic velocity of the California Current system. The TOPEX/Posiedon satellite measures SSH along an exact-repeat set of groundtracks with a 10-day repeat cycle. In the domain studied here...

Variability in mesoscale circulation and its effects on zooplankton distribution in the Northern California Current

Creator:: Keister, Julie Eileen
Abstract:: In eastern boundary current upwelling ecosystems, mesoscale circulation features such as eddies and upwelling filaments play a prominent role in the transfer of water and the associated plankton from the productive nearshore to the oligotrophic deep sea. The relationship between mesoscale circulation, zooplankton distributions, and the across-shelf transport of coastal...

Distribution, structure, and function of marine ecological communities in the northern California Current upwelling ecosystem

Creator:: Reese, Douglas Charles
Abstract:: Within systems characterized by substantial spatial and temporal variability, abundances of organisms tend to be higher in localized areas. Within the northern California Current system, the identification of such marine, biological hotspots would be of great importance to resource managers, conservationists, and research planners, and is consequently a growing area...

Bio-physical interactions of small pelagic fish schools and zooplankton prey in the California Current System over multiple scales

Creator:: Kaltenberg, Amanda May
Abstract:: Small pelagic fish represent a critical trophic link between plankton and large predators in marine upwelling ecosystems such as the California Current System. Populations of these fish are highly variable over time and are characterized by extreme fluctuations in abundance, which have significant ecosystem impacts. The causes driving this instability...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

Current measurements from moorings off Northern California, September 1984 - July 1985

Creator:: Smith, Robert L. (Robert Lloyd), 1935-, Pittock, Glenna, and Fleischbein, Jane
Abstract:: Three deep-sea subsurface moorings, each equipped with five current meters at depths from 150m below the surface to 200m above the bottom, were deployed off Northern California from September 1984 to July 1985 as part of the OPTOMA program. The triad of moorings, centered near 38.5°N, 125°W, had mutual separations...

Organization of persistent upwelling structures : hydrographic observations, 5 April-10 May 1983. Vol. 2

Creator:: Chelton, Dudley B., Paluszkiewicz, Theresa, Chandler, William, and Atkinson, Larry P.
Abstract:: The area near Point Arguello has long been recognized as a location of strong upwelling. A tongue of biologically active waters was observed in the earliest studies of this region (Sverdrup and Allen, 1939). More recently, satellite estimates of chlorophyll by the Coastal Zone Color Scanner (CZCS) on Nimbus-7 have...
