... ABSTRACT This paper describes several new developments in the evolution of side scan sonar sea bed mapping systems. A new advanced microprocessor-controlled tuning improves record quality. New deep tow vehicles allow for relatively high speed medium depth towing or low speed full ocean depth...

.... Techniques for the inspection of the submerged portions of structures by side scan sonar have been developed, field tested, and utilized in the arctic. Side scan records of sand bag slope protection and other shore protection structures have been obtained. Real-time side scan records were reviewed...

... Abstract Side-looking sonar records or images are often a valuable addition to conventional marine geophysical surveys. Recently, side-looking sonar images have been computer processed using software originally developed for planetary and terrestrial imaging missions. These general purpose...

The acoustic source is capable of producing a signal with sufficient bandwidth to achieve the required resolution and at the same time sufficient amplitude...

... of experience have been recorded and analyzed. The GAWWMP program made available, on magnetic tapes, some 322 million ocean wave and wind observations (Table 1). BOMP yielded approximately 238 thousand data observations, as only hourly observations of waves were recorded in BOMP. Products of the studies...

... ABSTRACT Oceanographic and meteorological data gathering, analysis, and recording on offshore structures and drilling rigs has been accomplished in several ways in the past. Pure analog recording of parameters with no real time analysis being performed has been used extensively. Digital...

... of the present state of the electronic art, and through the use of event-triggered data recording, it has proved possible to construct a system whose cost and operating power consumption are very low compared with what has been possible for systems of earlier design. In particular, these factors, low cost...

.... For more than a decade scientists have been able to install deep-ocean moored instrumented cable systems capable of recording oceanographic data. These moorings were first designed by "handbook engineering" followed by the application of tabular data which resulted from parametric analyses of current flow...

... ABSTRACT Sea trials were conducted on deep tow Sparker profiling equipment. Preliminary results indicate that data can be obtained of higher quality and in significantly worse sea conditions compared with equivalent surface towed systems. The addition of a tape recording facility should partly...

.... The usual spar buoy is from 50 to 100 feet in length, only a few inches in diameter and indeed, very awkward to handle. Various users have had success in attaching capacitive wave staffs to a spar buoy. The output of the staff can be delivered by a wire to the support ship or it can be recorded on board...
