Abstract | For multibeam swathmapping in the EM710 was used during the cruise M67/2. The EM710 installed is a new 1- by-1-degree broadband multibeam echosounder operating in the 70-kHz to 100-kHz band. It uses CW (continuous wave) pulses in shallow modes and FM (chirp) pulses in deep modes. The maximum water depth for this system is up to 1500 m to 2000 m, however, the most efficient depth range for the EM710 is less than 500 m. As the main area of investigation of Cruise M67/2 had water depths of more than 2000 m the EM710 was operated only in test mode e.g. close to Tampico. |
