AN UNBIASED VIEW OF HYDROGRAPHIC SURVEY

Data lower than 3dB can not be made use of as it establishes the maximum profiling number of the devices. It can be seen that SNR is close to 0 dB beyond 10m-12m depth. Again, through slack water, the Minimize off line for 3dB extends past as a result of existence of large turbidity in the water columns.Hydrographic surveying requires measuring all
