Bathymetric techniques and Indian Ocean applications
Abstract
The acoustic echosounders are the traditional workhorse of bathymetry measurements. The article highlights the differences between single beam and multibeam echosounders, besides indicating how complimentary they are to each other. It also explains the different steps of processing, backed by the examples as experiences of the authors of their use in the Indian Ocean. It proposes innovative and interesting approaches for data analysis. The article is backed with a short but complete bibliography illustrating clearly the traditional approach to bathymetry measurements.
