...-deepwater, marine archaeologists in the energy sector have greatly benefited from technological improvements originally aimed at the exploitation of offshore oil and gas. Beginning with echosounders, side-scan sonars, and magnetometers in towed arrays, before moving into high-resolution side-scan sonars...

... Abstract. TOBI is a new deep-towed geophysical surveying vehicle (figure 1) developed at the Institute of Oceanographic Sciences, Deacon Laboratory, U.K. Its standard instruments include: 31 kHz side-scan sonar (6 km swathe); a 7kHz high-resolution sub-bottom profiler (>50 metres...

... ABSTRACT Highlights of six years of side-scan sonar use to inspect and monitor a variety of coastal structures under various operating conditions are presented. As a result of these applications, several operational and interpretative guidelines have been developed. INTRODUCTION Side-scan...

.... These demonstrate the feasibility of mapping 100% of the seabed both in profile and contour at speeds up to 12 knots and in sea-states up to 6/7. INTRODUCTION Over the last decade substantial improvements have taken place in conventional surveying equipment, echo-sounders and side-scan sonar...

..., various seismic profilers, and side-scanning sonar. These sub-systems will be described in the following sections along with the micro-processor and how they are integrated operationally. THEORY AND DEFINITION The basic premises through which this system evolved are devoted to operational efficiency...

... was performed with a narrow-beam echo sounder and a side-scan sonar. In addition, potential areas were visually inspected by a two-man submersible and several subbottom profiling lines were run in favorable areas. REGIONAL SETTING Grand Bahama Island, an extensive carbonate shoal, is one of the two large...

The data conclusively show that the South Pass 70 "B" structure failed primarily because of sea floor soil movements. INTRODUCTION...
