In marine surveying and mapping work, a commonly used instrument is the echo sounder, also known as a depth sounder or sonar. The English abbreviation for this instrument is DE, which stands for Depth Echo.

The DE is an indispensable tool in oceanographic research, hydrographic surveys, and maritime navigation. It measures the depth of water by transmitting sound waves and analyzing the time it takes for the waves to travel from the instrument to the seabed and back. This information is then used to create depth profiles and bathymetric maps of the surveyed area., m- k! i- K/ N' G% z
