Ocean engineering with specialization in Underwater acoustics and data analysis


College or University: University of Rhode Island

Type of degree: M.S.

Brief overview of program: The Department of Ocean Engineering at the University of Rhode Island was the first institution (1966) to establish the M.S. and Ph.D. Degree in Ocean Engineering. High quality education and strong research have been the hallmark of the program since its inception. Over 300 students have graduated from the program. These students are employed by major corporations, small companies, large and small consulting firms, in addition to major government research laboratories. In brief, our students are found in all types of positions in a broad spectrum of working environments at both national and international levels. Prospective ocean engineering students can choose from a diverse group of graduate level courses in widely different ocean related subjects as a result of the broad and interdisciplinary background and research interests of the faculty . Opportunities exist for the student to work with an individual faculty menber or small groups of faculty members from other engineering departments and the Graduate School of Oceanography on specific problems in ocean engineering.

Description of Facilities: The Department of Ocean Engineering is located in the Sheets Building on the Narragansett Bay Campus, which also houses a marine geomechanics laboratory, a wave/tow tank facility, and faculty offices. The adjacent Middleton building contains office space, a machine shop, an acoustic test tank, an electronics laboratory, and an equipment staging area. The department also has computational facilities on the Bay Campus which include personal computers and SUN workstations. These computers are connected by high speed network to the rest of the Bay Campus, Kingston campus and the Internet. Over 3,000 square feet of laboratory space is available, with equipment specially designed for research and the testing of marine sediments in the Marine Geomechanics Laboratory. State-of-the-art geotechnical equipment is used for tests and studies on direct simple shear; anisotropic triaxial compression; drained creep; acoustic velocity; and special flow-pump systems for triaxial, permeability, and compressibility studies. The vessel also has a multi-sensor core logging system. Other associated facilities include X-ray diffraction equipment, a scanning electron microscope, and devices for seafloor sampling. The department maintains and operates a wave and tow tank that is 30 m long, 3.5 m wide, and 1.5 m deep. It is equipped with a flapper- type wave maker that generates both sinusoidal and random waves. A specially designed vertical multi-plate porous wave absorber is employed to damp waves. The tow carriage is equipped with a strain gauge system and is capable of making force and angular measurements of heave, roll, and yawing motions. The wave maker and data acquisition system are computer controlled and are capable of random or regular wave generation. Wave measurements are made using custom-designed wave height and pressure gauges. The tank has been used for a wide variety of experiments including ship resistance and propulsion, wave kinematics and dynamics, diver drag measurements, fishing trawl dynamics, buoy dynamics, and underwater vehicle drag. In the Middleton Building on the Narragansett Bay Campus, the department maintains and operates an acoustics test facility that is 4 m wide, 7.6 m long, and 3.6 m deep. It has two towers, with manual control in the horizontal direction and electrical control in the vertical. The towers can be rotated about the vertical axis with an accuracy of one degree. A third carriage, which is independent of the towers, is mounted on a separate track. A computer data acquisition system processes the data. The tank is filled with fresh water, which is cleansed by a standard filtration system. This facility has been used for extensive experiments including beam pattern measurements of acoustic transducers and arrays, studies of acoustic parametric sources, and the development of subbottom profiling sonar systems and underwater diver communication systems.
