Aquantis, LLC, Santa Barbara, California intends to construct and deploy an ocean current turbine (C-Plane) to extract electrical power from the kinetic energy of the Florida Current. This study characterizes the physical oceanographic environment of the Florida Current flow, at a proposed deployment site located at 26.11 North Latitude, 79.50 West Longitude, which will influence the physical and mechanical design of the C-Plane. Local characteristic features of the Florida Current were...
Show moreAquantis, LLC, Santa Barbara, California intends to construct and deploy an ocean current turbine (C-Plane) to extract electrical power from the kinetic energy of the Florida Current. This study characterizes the physical oceanographic environment of the Florida Current flow, at a proposed deployment site located at 26.11 North Latitude, 79.50 West Longitude, which will influence the physical and mechanical design of the C-Plane. Local characteristic features of the Florida Current were determined from data collected during a 19 month in situ study using an Acoustic Doppler Current Profiler (ADCP) moored at 330 meters, a ship-mounted, inertial-correcting ADCP, and data culled from adjacent studies. Principles of physical oceanography and direct observations are applied to characterize the velocity structure of the current and its variability. This thesis presents the motivation behind the study, methods of data collection, statistical and numerical analyses, and available energy analyses.

Six survey missions of one day duration were preformed at 26°N latitude off the coast of south Florida in order to examine the characteristics of the Florida Current front on the coastal side of the current. Observations were made from the R/V Stephan using a conductivity, temperature, and depth (CTD) package and an acoustic Doppler current profiler (ADCP), corresponding meteorological observations were recorded by NOAA C-MAN stations at Fowey Rocks and Lake Worth Florida. The six survey...
Show moreSix survey missions of one day duration were preformed at 26°N latitude off the coast of south Florida in order to examine the characteristics of the Florida Current front on the coastal side of the current. Observations were made from the R/V Stephan using a conductivity, temperature, and depth (CTD) package and an acoustic Doppler current profiler (ADCP), corresponding meteorological observations were recorded by NOAA C-MAN stations at Fowey Rocks and Lake Worth Florida. The six survey missions were preformed over an 8-month period of March 2002 to October 2002. The data collected confirms observations made by previous theoretical studies, which used dynamical models of the Florida Current. The overall picture is of a turbulent cyclonic front with strong vertical shearing and vertical mixing. In addition, the data suggest internal wave generation and intermittent episodes of upwelling that appear to be related to the position of the current and the steepness of the front.

The mechanisms of larval fish transport have been rigorously studied in the past several decades, building foundational knowledge of key biological and environmental factors with which to inform decisions about species management. This study has been built upon information gained from previous studies to further elucidate the processes involved at the recruitment stage of larval fishes.

Show moreThe mechanisms of larval fish transport have been rigorously studied in the past several decades, building foundational knowledge of key biological and environmental factors with which to inform decisions about species management. This study has been built upon information gained from previous studies to further elucidate the processes involved at the recruitment stage of larval fishes. Vertical swimming behaviors of larval fishes enable deliberate orientation within the water column to allow organisms of limited mobility greater control over their horizontal movements. Vertical accumulation patterns of larvae are found to be tightly dependent on the strength of stratification within the water column at nursery entrances, such as estuaries. Onshore currents, such as upwelling and surface intrusions, are found to be conduits for entry into these systems. This study observed and analyzed the influence of intrusions by the Gulf Stream into the Fort Pierce Inlet and the vertical accumulation patterns of late-stage larvae associated with those events. This study incorporated a well-established zooplanktonic abundance sampling technique to achieve two primary goals: (1) to analyze the vertical abundances of larval fishes in stratified flow during Gulf Stream intrusions and (2) to assess the correlation between larval influx and intrusion events. The results of this study show a significant and positive correlation between propagule pressure of larval fishes and incidence of Gulf Stream intrusion events. Whereas previous studies have primarily described the spatiotemporal aspects of larval transport in a broader sense, our findings revealed a greater layer of complexity in the mechanisms of transport by incorporating localized hydrographic features. The information gleaned from these results can inform the ecological considerations of future fisheries management and study efforts via additional understanding about the role of physical oceanographic events in a critical life stage.

- Characterization of Internal Wave Activity in the Straits of Florida.

- Abstract/Description
-
The Gulf Stream current in the Straits is typically dominated by a strong northerly current, associated shear, and eddies. The water column also includes a prominent thermocline and periodically features internal waves centered on the upper or lower edges of the thermocline. Despite numerous previous related studies, there is limited available field data on internal waves in the Straits of Florida. Here, study and analysis of velocity, temperature and conductivity data acquired in the Straits...
Show moreThe Gulf Stream current in the Straits is typically dominated by a strong northerly current, associated shear, and eddies. The water column also includes a prominent thermocline and periodically features internal waves centered on the upper or lower edges of the thermocline. Despite numerous previous related studies, there is limited available field data on internal waves in the Straits of Florida. Here, study and analysis of velocity, temperature and conductivity data acquired in the Straits over a period of time are described, in support of identifying presence of internal waves in the flow. A systematic procedure is employed in modifying the universal Garrett- Munk spectrum for internal waves in the open ocean for application to flow in the Straits of Florida. Using this process, identified internal waves are characterized and related velocity fluctuations in the time series are isolated to facilitate consideration of their correlations with simultaneously observed magnetic fields.

- Abstract/Description
-
The study addresses the coating selection for a proposed placement of a hydroturbine into the Gulf Stream. The turbine will generate energy in a similar manner to a wind turbine. The effects of biofouling and corrosion in the current project are assessed. A review of different types of traditional paint coatings is given, as well as the option for a copper-nickel alloy. Testing that should be undertaken for the coating selection is described in detail. Coating considerations are offered and...
