DTIC ADA068875: A Synopsis of Marine Animal Underwater Sounds in Eight Geographic Areas

The purposes of this report are to list the soniferous marine animals that occur in eight geographic areas of interest, to rank them according to their importance as sound producers, and to describe certain features of their sounds. The geographic areas are identified in a separate enclosure that accompanies this report. In preparing the information, over 200 papers were reviewed for their applicability to the general needs of the project. Although all of the data included here pertain to marine mammals, we would also expect to find soniferous fishes at all of these areas. However, information on fish acoustics is not presented for the areas, either because it was to scanty, or it did not exist. For the most part, fish sounds are relatively low-level transients that would not seem to apply to this problem. Elsewhere, certain species of fish are known to emit high-level choruses in the early morning or evening hours, but it is not known whether or not these phenomena also occur in the subject areas.
