Deep-tow side scan sonar systems have also been utilised in past exploration programmes to provide textural information useful in mapping the seafloor geology, and are able to provide data at resolutions better than that of vessel...

... and/or investigated using C & C s AUVs. Several of those surveys resulted in new discoveries and at least, thirteen of the wrecks have been confirmed to be historic vessels. The initial primary geophysical instrument payload of the HUGIN model AUV consisted of dual frequency side scan sonar, subbottom profiler...

... to the nature of the fluid flow, and potentially the associated carbonates and fauna, we then require acoustic data with relevant signal processing, including side scan sonar, swathe bathymetry backscattering, and 3D seismic attributes. This paper will review briefly why carbonates may occur within some...

Abstract An Autonomous Underwater Vehicle (AUV) geophysical sur- vey that acquired detailed bathymetry, side scan sonar, and sub-bottom acoustic profiling was used to identify potential hydrocarbon seep features in Green Canyon Block 607 and 608, west of the Marco Polo field...

... of seafloor features including large high-angle fault scarps (up to 100-feet in relief), a mud volcano (250-feet in relief), two mud vents, multiple mound-like structures, hard grounds, and mudflows. Multibeam bathymetry, side scan sonar, and sub-bottom profiles were collected across the site at a 200-meter...

... required for seismic risk analysis. In order to achieve these objectives, a high-resolution multibeam echosounder, side scan sonar and Chirp sub-bottom profiler was mounted on an ROV to reduce the water column height between the sensors and the seabed. This resulted in increased data accuracy...

... 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...

... ABSTRACT Echo sounding, side scan sonar and seismic profi1ing records have shown that the continental shelf of the Canadian Beaufort Sea has been subjected to extensive scouring by ice features. The scouring phenomena is extremely important in the design and protection of offshore well s...

.... 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 The conventional presentation of the data from a side scan sonar suffers from several types of distortion. Until these distortions are removed, sonar images from two or more overlapping passes through an area can not be combined to form a "mosaic." The major distortions arise from...

... ABSTRACT Echo sounding, side scan sonar and seismic profile records in the Canadian Beaufort Sea provide evidence of trenches or "scours" on the continental shelf sea bottom. These are generally believed to be caused due to grounding of ice masses. Records obtained over a three year period...
