Applied Underwater Acoustics

7.4. Some Newer Topics

Although shallow-water acoustics is a well-developed area of ocean acoustics at this point in time, there are still some new topics to research. We look, in a broad-brush sense, at three of them, namely (1) canyons, the continental slope, and the shelf break; (2) arctic shallow-water acoustics; and (3) climate change effects on shallow-water acoustics.

7.4.1. The Shelf Break, Slope, and Canyon Regions and the Transition to Deep Water

The shelf break, slope, and canyon regions are of course not entirely new topics, but it is safe to say that, due to their complicated natures, it is only recently that we can address them rigorously via theory, experiment, and numerical modeling. Geologically, the shelves, slopes, and canyons ...
