Title: EXCITATION OF EDGE WAVES BY WAVES OBLIQUELY INCIDENT UPON A BEACH.
Creator: CHANG, YUH-HUEI., Florida Atlantic University, Lin, Newman K.
Abstract/Description: Edge waves are the longshore periodic wave motions that are trapped at the edge of water bodies and play an important role in coastal hydrodynamics. This study presents the experimental investigation of the excitation of synchronous edge waves by waves normally and obliquely incident on a uniformly sloping beach. The experimental results show that the edge wave amplitude is linearly proportional to that of the reflected waves. For a perfectly reflecting beach, the conclusion is consistent...
Show moreEdge waves are the longshore periodic wave motions that are trapped at the edge of water bodies and play an important role in coastal hydrodynamics. This study presents the experimental investigation of the excitation of synchronous edge waves by waves normally and obliquely incident on a uniformly sloping beach. The experimental results show that the edge wave amplitude is linearly proportional to that of the reflected waves. For a perfectly reflecting beach, the conclusion is consistent with the Rockliff model. The experimental results also indicate that the ratio of the edge wave amplitude to reflected amplitude is linearly proportional to the approach angle.

Title: EXCITATION OF EDGE WAVES ON AN EXPONENTIAL BEACH.
Creator: LIU, JONG-YU., Florida Atlantic University, Lin, Newman K., College of Engineering and Computer Science, Department of Ocean and Mechanical Engineering
Abstract/Description: Edge waves are the longshore, trapped waves; their amplitude diminishes exponentially seaward from the shoreline. Ursell [1] has shown that there is a family of edge wave solutions of the shallow water equations, and Ball [2] provided a normal mode solution for the exponential beach. This study investigated, experimentally, the excitation of edge waves on a concave exponential beach by waves normally incident on the beach. The experimental investigation included the study of edge wave...
Show moreEdge waves are the longshore, trapped waves; their amplitude diminishes exponentially seaward from the shoreline. Ursell [1] has shown that there is a family of edge wave solutions of the shallow water equations, and Ball [2] provided a normal mode solution for the exponential beach. This study investigated, experimentally, the excitation of edge waves on a concave exponential beach by waves normally incident on the beach. The experimental investigation included the study of edge wave frequency, amplitude and particle motions. The results indicated that resonance occurs under suitable conditions for edge wave excitation. Viscosity, nonlinearity and defraction at the beach sidewalls reduced agreement between experiments and theory. The effects of these parameters on edge waves should be explored in more detail in further research.

Show moreThis thesis describes an active sonar mounted to an Autonomous Underwater Vehicle (AUV) for measuring bubble clouds below breaking waves. A new development is the application of a very broadband sonar signal-processing scheme for the sonar. It is shown that using the active sonar on an Autonomous Underwater Vehicle provides reliable data and that good results are obtained by using a correlation processor. This thesis describes the optimum processing procedure for this application, resolution, and signal to noise constraints. Experimental results are given which show that bubbles can be imaged using an active sonar from an AUV platform. It was shown in the experimental results that the additive and the multiplicative processing produced good results for different situations. The multiplicative procedure was more consistent in the identification of bubble clouds than the additive process. One could see from the multiplicative images for the sea experiment where the bubble clouds were located while in the additive images one could only tell that a bubble cloud was identified.

Show moreThe following study explores the worldwide spatial and temporal distributions of electrical power that can be extracted from the ocean's stored solar energy via the process of closed-cycle ocean thermal energy conversion (OTEC). Special emphasis is placed on resources surrounding the state of Florida. The study combines oceanographic input from a state-of-the-art ocean circulation model, the Hybrid Coordinate Ocean Model, with a state-of-the-industry OTEC plant model to predict achievable power values across the world. These power predictions are then constrained by local replenishment rates of cold deep sea water to provide an upper limit to the sustainable OTEC resource. Next, the geographic feasibility of OTEC-coupled and OTEC-independent sea water cooling (air conditioning and refrigeration) are explored. Finally, the model data is validated against in situ oceanic measurements to ensure the quality of the predictions.

Title: Three-Dimensional Inversion Technique in Ocean Acoustics Using the Parabolic Equation Method.
Creator: Roa, Camilo Carlos, Frisk, George V., Florida Atlantic University, College of Engineering and Computer Science, Department of Ocean and Mechanical Engineering
Abstract/Description: A three-dimensional parabolic equation (PE) and perturbation approach is used to invert for the depth- and range-dependent geoacoustic characteristics of the seabed. The model assumes that the sound speed profile is the superposition of a known range-independent profile and an unknown depth- and range-dependent perturbation. Using a Green’s function approach, the total measured pressure field in the water column is decomposed into a background field, which is due to the range-independent...
Show moreA three-dimensional parabolic equation (PE) and perturbation approach is used to invert for the depth- and range-dependent geoacoustic characteristics of the seabed. The model assumes that the sound speed profile is the superposition of a known range-independent profile and an unknown depth- and range-dependent perturbation. Using a Green’s function approach, the total measured pressure field in the water column is decomposed into a background field, which is due to the range-independent profile, and a scattered field, which is due to the range-dependent perturbation. When the Born approximation is applied to the resulting integral equation, it can be solved for the range-dependent profile using linear inverse theory. Although the method is focused on inverting for the sound speed profile in the bottom, it can also invert for the sound speed profile in the water column. For simplicity, the sound speed profile in the water column was assumed to be known with a margin of error of ± 5 m/s. The range-dependent perturbation is added to the index of refraction squared n2(r), rather than the sound speed profile c(ro). The method is implemented in both Cartesian (x,y,z) and cylindrical (r,q,z) coordinates with the forward propagation of the field in x and r, respectively. Synthetic data are used to demonstrate the validity of the method [1]. Two inversion methods were combined, a Monte Carlo like algorithm, responsible for a starting approximation of the sound speed profile, and a steepest descent method, that fine-tuned the results. In simulations, the inversion algorithm is capable of inverting for the sound speed profile of a flat bottom. It was tested, for three different frequencies (50 Hz, 75 Hz, and 100 Hz), in a Pekeris waveguide, a range-independent layered medium, and a range-dependent medium, with errors in the inverted sound speed profile of less than 3%. Keywords: Three-dimensional parabolic equation method, geoacoustic inversion, range-dependent sound speed profile, linear inversion, Born approximation, Green’s functions.

Title: A resource assessment of Southeast Florida as related to ocean thermal energy.
Creator: Leland, Anna E., College of Engineering and Computer Science, Department of Ocean and Mechanical Engineering
Abstract/Description: An assessment of the thermal resource in the Straits of Florida was performed to estimate the Ocean Thermal Energy Conversion (OTEC) potential. Direct measurements of the temperature profile across the Florida Straits were taken from nearshore Southeast Florida to the Exclusive Economic Zone boundary along four evenly spaced transects perpendicular to Florida's Southeast coast, spanning 160 km. Along the southern transects in summer, nearshore cold and warm water resources meet or exceed the...
Show moreAn assessment of the thermal resource in the Straits of Florida was performed to estimate the Ocean Thermal Energy Conversion (OTEC) potential. Direct measurements of the temperature profile across the Florida Straits were taken from nearshore Southeast Florida to the Exclusive Economic Zone boundary along four evenly spaced transects perpendicular to Florida's Southeast coast, spanning 160 km. Along the southern transects in summer, nearshore cold and warm water resources meet or exceed the average 20ÀC temperature difference required for OTEC. In winter, the nearshore average DT of 17.76ÀC can produce 59-75% design net power and 70-86% in spring with DT averaging 18.25ÀC. Offshore along the southern transects, a high steady DT from 18.5- 24ÀC creates an annual average net power of 120-125MW. Along the northern transects, the nearshore resource does not exist, but a consistent OTEC resource is present offshore, providing 70-80% design net power in winter, and 100-158% in spring and summer.

Show moreThe Buried Object Scanning Sonar (BOSS) is being developed at Florida Atlantic University to image targets buried under the seabed. Tomographic images are constructed using a sequence of sonar transmissions while the vehicle is moving. This motion causes image distortion and should be measured and removed by mapping the echoes received to an absolute coordinate system. The aim of this thesis is to develop and simulate a technique for generating BOSS images that provide an accurate representation of target shape and size, by removing vehicle motion while mapping the image pixels. Synthetic acoustic data sets are generated by convolving the auto-correlated FM transmission pulse with the impulse response of an elastic sphere. Synthetic outputs of a Doppler velocity log and a 3-axis inertial measurement unit are generated to simulate vehicle motion. Noise is added to the sensor data to show the effects of motion sensor errors on image quality.

Title: Spatial and trophic ecology of the sawtooth eel, Serrivomer beanii, a biomass-dominant bathypelagic fish over the northern Mid-Atlantic ridge.
Creator: Geidner, Megan E., Charles E. Schmidt College of Science, Department of Biological Sciences
Abstract/Description: The role of Serrivomer beanii in bathypelagic food webs is poorly known, but abundance and biomass estimates from the 2004 G.O. Sars MAR-ECO Expedition suggest it to have a high level of importance. MAR-ECO, a Census of Marine Life field project, has allowed us to increase our knowledge of S. beanii through spatial analysis, including the congeneric species Serrivomer lanceolatoides, and trophic analysis.

Show moreThe role of Serrivomer beanii in bathypelagic food webs is poorly known, but abundance and biomass estimates from the 2004 G.O. Sars MAR-ECO Expedition suggest it to have a high level of importance. MAR-ECO, a Census of Marine Life field project, has allowed us to increase our knowledge of S. beanii through spatial analysis, including the congeneric species Serrivomer lanceolatoides, and trophic analysis. Serrivomer beanii abundance and biomass exhibited a decreasing trend along the northern Mid-Atlantic Ridge from north to south. In terms of size, S. beanii was found to increase as distance from the ridge decreased, suggesting a topographic aggregation strategy. The diet of S. beanii consisted of crustaceans, cephalopods, and teleosts. The trophic results of this study reveal a likely "alternative" trophic pathway in the deep mid-North Atlantic, and perhaps other, bathypelagic ecosystems: higher trophic-level predators are supported by micronektonic invertebrates as primary prey.
