SITE SURVEY OF THE SOUTHERN PORTION OF THE SAN JUAN SEAMOUNT

Abstract

As coparticipants with the Naval Underseas Warfare Center, San Diego, in a program to install the transmission end of an interseamount acoustic range, NCEL conducted a site survey of the southern portion of the San Juan Seamount. A detailed topographic chart was developed for the area, underwater photographs were taken and water and sea floor samples were collected and analyzed. It was found that the surface of the area is irregular and rough; it is volcanic in origin, consisting of vesicular basalt bearing a ferro-manganese coating. The current at depth is judged to be slight - no greater than 1 knot. It is anticipated that unless the biological and chemical environment is materially changed locally by acoustic energy or heat emission from the operation of the installed equipment, no more than normal corrosion or fouling will result.
