Such observations are very difficult to make from the ocean surface. Acoustical Studies The increasing use of sonar in fishing makes it important to study its effectiveness in differentiating fish species--either by a characteristic signal return from one fish, or by signal recognition of swimming or school- ing behavior of a group of fish. TEKTITE I will be an unique opportunity to identify sonar target species and correlate them with their acoustical "; TEKTITE SITE The site of TEKTITE I is Beehive Cove in Greater Lameshur Bay, on the south shore of St. John Island in the Virgin Islands, about 900 miles southeast of Miami, Florida. The cove is in Virgin Islands National Park, ad- ministered by the National Park Service. The water is very clear and warm, and tropical plant and animal life is abundant. The many coral reefs are home to vast reef- fish populations, spiny lobsters, and other marine Fig. 4-TEKTITE SITE.
