Acoustic scattering by axisymmetric finite-length bodies with application to fish : measurement and modeling
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2002-06)
This thesis investigates the complexities of acoustic scattering by finite bodies in general and by fish in particular through the development of an advanced acoustic scattering model and detailed laboratory acoustic ...
Design considerations for engineering autonomous underwater vehicles
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2007-06)
Autonomous Underwater Vehicles (AUVs) have been established as a viable tool for Oceanographic Sciences. Being untethered and independent, AUVs fill the gap in Ocean Exploration left by the existing manned submersible ...
Absarokites from the Western Mexican Volcanic Belt : constraints on mantle wedge conditions
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2002-08)
We have investigated the near liquidus phase relations of a primitive absarokite from the Mascota region in Western Mexico. Sample M.102 was chosen because it has high MgO contents, a high Mg# and F090 olivine phenocrysts, ...
Analysis of 2-axis pencil beam sonar microbathymetric measurements of mine burial at the Martha’s Vineyard Coastal Observatory
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2005-09)
The changing state of warfare has driven the US Navy's area of operations closer to shore into littoral coastal waters. Mine Warfare has been proven as an extremely effective means of battlespace control in these ...
Experimental stress analysis of model of emergency forebody release device used in deep diving research submarines Alvin, Sea Cliff and Turtle
(Woods Hole Oceanographic Institution, 1969-08)
Tests were conducted on a full-scale model of the emergency forebody release used in the deep-diving submarines ALVIN, SEA CLIFF and TURTLE. The model was machined from metal to the same dimensional tolerances as the ...
Torque tests of a full size model of the Alvin/AUTEC emergency sphere release
(Woods Hole Oceanographic Institution, 1970-11)
Laboratory torque tests were perfoirmed using an actual emergency sphere release shaft of the type used in the research submarines ALVIN, SEA CLIFF and TURTLE. A test fixture was constructed which permitted laboratory ...
Summary of current meter operations in 1968
(Woods Hole Oceanographic Institution, 1969-03)
This report describes work done with Geodyne current meters and wind recorders during 1968. Techniques for testing instruments prior to use at sea, instrument performance at sea and instrument changes evolved during the ...
Bibliography of technical reports for 1994 and 1995
(Woods Hole Oceanographic Institution, 1996-12)
The technical report and theses prepared by the Woods Hole Oceanographic Institution in 1994 and 1995 are listed in ths bibliography.
Loose-tube neutral tether fiber optic termination procedure
(Woods Hole Oceanographic Institution, 2001-06)
Neutral tethers for unmanned underwater vehicles may contain a bundle of single-mode, optical fibers that are protected inside flexible stainless steel tubing. To date the author knows of no commercially available systems ...
Development of a "genome-proxy" microarray for profiling marine microbial communities, and its application to a time series in Monterey Bay, California
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2008-09)
This thesis describes the development and application of a new tool for profiling marine microbial communities. Chapter 1 places the tool in the context of the range of methods used currently. Chapter 2 describes the ...
