Abstract

Single Beam Echosounder (SBES) is the first modern technique used to acquire bathymetric data. This system was introduced since early 1960’s. SBES has a simple operating principle with small error budget. However, SBES can be considered inadequate to meet modern standard in hydrographic surveying. SBES did not provide continuous, gap-free coverage of the bottom neither satisfies the needs of present users nor the need of modern commercial shipping. SBES also is a time consuming system due to the fact that closer sounding line needs to be surveyed to get good contour interpretation. Survey lines need to be plan carefully and this depends on the complexity of the seabed. In hazardous waters, complete coverage of the bottom is required. Most of today’s users require such information, which exactly describes not only the sea depths, isobaths, underwater obstacles and nature of bottom but also the sea bottom sediment movement and subbottom layers.
