Atmospheric interactions with Gulf Stream Rings
Four different problems concerning Gulf Stream Rings are considered. The first deals with the particle trajectories of, and advection-diffusion by, a dynamic model of a Ring. It is found that the streaklines computed from the assumptions that the Ring is a steadily propagating and permanent form …

Generation and maintenance of recirculations by Gulf Stream instabilities
… generation and maintenance of recirculations by Gulf Stream instabilities. Observations show that the horizontal structure of the jet and its recirculations suffer significant changes in time. Here, the role of internal dynamics of the jet is isolated as one of the possible sources of such …

Temporal, spatial and pulse instabilities of the Gulf Stream
… theory- is the most appropriate model for the Gulf Stream?" I also address the question of how the observations might be compared to theory. This thesis consists of two closely related parts: analytical studies that compare the three types of instability using the same realistic velocity and …

Gulf Stream temperature, salinity and transport during the last millennium
… Straits of Florida reveal significant changes in Gulf Stream cross-current density gradient during the last millennium. These data imply that Gulf Stream transport during the Little Ice Age (LIA: 1200-1850 A.D.) was 2-3 Sv lower than today. The timing of reduced flow is consistent with cold …

Flow Kinematics and Dynamics of the Gulf Stream From Composite Imagery
… near-surface flow kinematics and dynamics of the Gulf Stream. Using fractal and spectral analyses, two kinematic models, and a potential vorticity model, detailed comparisons are made between these data sets.</p> <p>Fractal and spectral analyses show that the data set is not fractal, there is no …

Instability Waves in the Gulf Stream Front and Its Thermocline Layer
… calculations were carried out on a three layer Gulf Stream front model in an attempt to elucidate the interaction of the thermocline layer with surface slopewater shoreward of the front. The basic state is geostrophic balance and constant potential vorticity in the two active layers, but the …

The entrainment and homogenization of tracers within the cyclonic gulf stream recirculation gyre
… with the Northern Recirculation Gyre of the Gulf Stream (NRG) are studied to try to obtain information about the flow. An advective-diffusive numerical model is implemented to aid in the investigation. The model is composed of a gyre adjacent to a boundary current in which a source of tracer …

Nonlinear Solutions to a Two-Layer Quasi-Geostrophic Model of the Gulf Stream
<p>The Gulf Stream shows a large meander off Cape Hatteras. This is driven by an energy conversion process known as baroclinic instability and observations suggest that nonlinearity is an important part in this process. In order to understand the fundamental role of nonlinearity in baroclinic …

Submesoscale Biophysical Interactions on the Gulf Stream: Eddies, Fronts, and New Observational Methods
… fronts of western boundary currents like the Gulf Stream are hotspots for submesoscale dynamics that may influence phytoplankton productivity and diversity with ramifications across marine ecosystems. In this dissertation I: 1) review the use of drones and ocean color remote sensing for …
