A technical description of an acoustic Doppler based upper ocean profiling system
MetadataShow full item record
An acoustic Doppler profiler has been designed into a multi-sensor Acoustic Profiler of Ocean Currents system (APOC). All four major components of this data collecting ensemble are microprocessor based units, allowing programmatic flexibility. Various water column, meteorological, and navigation data are recorded in a raw and/or processed form. Plots and listings of processed data are generated and displayed in real-time for use by investigators. Once installed, the system requires only a periodic change of cartridge recording media. The equipment has collected data during five cruises, for a total of approximately 190 days at sea. A hardware and software description of the system is presented. Preliminary technical results are discussed and evaluated.

(Acoustical Society of America, 2013-10)Ocean bottom seismometer observations at 5000 m depth during the long-range ocean acoustic propagation experiment in the North Pacific in 2004 show robust, coherent, late arrivals that are not readily explained by ocean ...
Observationally constrained modeling of sound in curved ocean internal waves: Examination of deep ducting and surface ducting at short range Duda, Timothy F.; Lin, Ying-Tsong; Reeder, D. Benjamin (Acoustical Society of America, 2011-09)A study of 400 Hz sound focusing and ducting effects in a packet of curved nonlinear internal waves in shallow water is presented. Sound propagation roughly along the crests of the waves is simulated with a three-dimensional ...
Low-frequency broadband sound source localization using an adaptive normal mode back-propagation approach in a shallow-water ocean Lin, Ying-Tsong; Newhall, Arthur E.; Lynch, James F. (Acoustical Society of America, 2012-02)A variety of localization methods with normal mode theory have been established for localizing low frequency (below a few hundred Hz), broadband signals in a shallow water environment. Gauss-Markov inverse theory is employed ...
