Modeling studies of ocean circulation using inverse methods and bifurcation theory

Creator:: Vernieres, Guillaume
Abstract:: We present a study of the ocean circulation using state of the art numerical and data assimilation techniques. The second chapter of the thesis presents the development and application of generalized inversion to a simple dynamical model of Lake Kinneret. The intent was to develop the necessary tools to implement...

Modeling studies of the coastal circulation off northern California

Creator:: Pullen, Julie D.
Abstract:: By implementing a series of mass-conserving nested high-resolution models down to approximately 1 km resolution that have realistic bathymetry, coastline, wind forcing and river run-off, the winter 1996-1997 shelf flow near Cape Mendocino, California, is simulated and compared with available observations from the Strata Formation on Margins (STRATAFORM) marine geology...

Development, performance evaluation and application of a physical model of the Kenyan-Tanzanian coastal region

Creator:: Mayorga Adame, Claudia Gabriela
Abstract:: A Regional Ocean Modeling System (ROMS) application for the coastal region of Kenya and Tanzania (0-10° S, 38.7-46.98° E) was developed with the aim of better resolving the circulation patterns in the coastal region that is poorly represented in global models. The model has a horizontal resolution of 4 km,...

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...

Spatial structure of the physical and biological distributions across the Antarctic Polar Front in austral spring and summer

Creator:: Howard, Cidney
Abstract:: Mesoscale surveys to examine the relationship between the physical processes and biological response along the Antarctic Polar Front (PF) were conducted as part of the US JGOFS Southern Ocean Program during austral spring and summer 1997/98. Multiple crossings of the PF near 170° W, using a towed undulating instrument, provided...

Sea surface water motion off Chile latitudes18°S-40°S, revealed from satellite images ofchlorophyll and temperature distribution

Creator:: Espinoza, Felix R.
Abstract:: The mesoscale sea-surface circulation pattern within 400 km off Chile and between 18°S and 40°S latitude is described using chlorophyll and temperature images from the Coastal Zone Color Scanner NIMBUS-7 satellite. The data base is a set of four mosaics developed from band-3 (550 nm) images taken on June 4...

Numerical and assimilative studies of the equatorial Pacific cold tongue

Creator:: Perez, Renellys Christine
Abstract:: Numerical model and assimilation experiments were conducted in the tropical Pacific Ocean to obtain a better understanding of the processes that control the cold tongue surface mixed layer temperature balance during August 1999 to July 2004. The numerical model was first applied to test two hypotheses (asymmetric background currents and...

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...

Influence of a Sedimentary Source of Nd on Deep Ocean εNd Distributions

Creator:: Abbott, April N.
Abstract:: Ocean circulation is an important component in Earth's climate system. Predicting future climate and circulation changes requires an improved understanding of the past relationship between climate and ocean currents. The neodymium isotope composition (εNd) of water masses is frequently used as a quasi-conservative tracer to reconstruct ocean circulation. The current...
