Feasibility study of non-invasive telemetry techniques for use with submarine telephone cables
(Woods Hole Oceanographic Institution, 1993-01)
The feasibility of using inductive coupling with existing submarine telephone cables for telemetry of data from ocean sensors was investigated. The submarine telephone cable was simulated with a computer model and the ...
Smoothly modulated frequency-bounded impulse signals for tomography
(Woods Hole Oceanographic Institution, 1991-06)
A group of amplitude and frequency modulated signals which generate narrow synthesized pulses and which also have smoothly varying phase are described. The frequency-sweep (chirp) signals have exactly-defined frequency ...
A SAIL compatible three channel acoustic navigation interrogator
(Woods Hole Oceanographic Institution, 1990-09)
Ocean Acoustic Tomography data are significantly degraded if mooring motion is unknown. An autonomous instrument employing a solid state data logger designed to track and record mooring motion is described. Navigation ...
The N456 Navigator system
(Woods Hole Oceanographic Institution, 2009-01)
The N456 Navigator has been developed to assist in Long Baseline (LBL) acoustic navigation. Its two basic functions are generation of acoustic signals, and receipt and timing of returns. When combined with the new dsnav ...
CTD electromechanical termination users manual
(Woods Hole Oceanographic Institution, 1990-08)
This report desribes a new, easy to install, reliable electromechanical cable termination to mechanically attach and electrically connect cable lowered instrument packages to their lowering cable.
Universal criteria for blind deconvolution
(Woods Hole Oceanographic Institution, 1990-02)
We present necessary and sufficient conditions for blind equalization/deconvolution (without observing the input) of an unknown, possible non-minimum phase linear time invariant system (channel). Based on that, we propose ...
Ocean acoustical ray-tracing : Software Ray
(Woods Hole Oceanographic Institution, 1992-10)
A new computer program for accurate calculation of acoustic ray paths through a range-varing ocean sound channel has been written. It is based on creating a model of the speed of sound in the ocean, consistent with input ...
Initial results from a cartesian three-dimensional parabolic equation acoustical propagation code
(Woods Hole Oceanographic Institution, 2006-12)
A three-dimensional (3D) parabolic equation acoustical propagation code has been developed and run successfully. The code is written in the MATLAB language and runs in the MATLAB environment. The code has been implemented ...
Coastal ocean processes symposium : a tribute to William D. Grant, September 27 - September 30, 1998
(Woods Hole Oceanographic Institution, 1999-05)
This report is a compilation of abstracts distrbuted at the Coastal Ocean Processes Symposium: A Tribute to Willam D. Grant at the Woods Hole Oceanographic Institution from September 27 - September 30, 1998.
Electronic still camera processing and mosaicking
(Woods Hole Oceanographic Institution, 1999-12-23)
Since 1990, the Deep Submergence Laboratory and Deep Submergence Group of the Woods Hole Oceanographic Institution have been collecting large quantities of digital imagery and creating digital photomosaics of the sea ...
