Purpose
Abstract The EM 710 was seldomly used during the cruise M76/3a. It uses a frequency range from 70 to 100 kHz and is optim ized to survey with higher resolution in water depths shallower than 1,000 m depth. As most of the working area during M76/3a was deeper than 1000 m , the EM 710 system was not used very often.
