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.
