Abstract:
This presentation will introduce the audience to
the basic elements of Underwater Acoustics. In particular,
it will address issues such as how complications in
the ocean environment affect ocean sound propagation.
These issues include: water temperature and pressure,
boundary roughness and elasticitiy, bottom topography
(canyons, seamounts, etc.), bubbles, fish, inhomogeneities,
and more. Additional considerations include mention of
other technical fields of importance and their
associated calculations. Technical details will be kept
to a minimum and only basic math and physics will be
assumed. In the end, all the complications of the ocean
can help locate such objects as submarines (as in
the Hunt for Red October), fish, manganese nodules,
and more - if one can adequately describe the ocean
scenario.
