Purpose | |
Abstract | The EM120 system was used for mapping during the cruise.The EM120 system is a multibeam echosounder (with 191 beams) providing bathymetric mapping up to depths exceeding 11000 m. This system is composed of two transducer arrays fixed on the hull of the ship, which send successive frequency coded acoustic signals (11.25 to 12.6 kHz). |
