Coastal Hydrographic Sonar/Advanced Acoustic Techniques Technology Assessment Report
Abstract
Technological options for increasing the productivity of hydrographic survey launches are reviewed, based on observations of the Naval Oceanographic Office survey operations in the Golfe de la Gonave, Haiti, during May 1982. It was found that multi-beam sonars have the potential to increase productivity by 50% in terms of area surveyed per day per launch for water depths between 75 and 200 meters, or possibly by 100% over the very limited depth range of 145 to 200 meters. By contrast, under the operating conditions observed during the May 1982 operation in Golfe de la Gonave, major improvements in reliability and maintainability combined with use of the new LCP(L) MK-12 launches can potentially increase productivity by up to 310%. Sector-scan sonars were found to have an attractive potential for detection of navigation hazards between sounding lines, mapping the perimeters of hazardous areas, and reconnaissance and survey planning. These capabilities will increase productivity provided the sonars are designed for operation at normal survey speeds. (Author)
