Our latest generation of multibeam echosounders has passed initial trials onboard the Royal Navy ice patrol ship, HMS Endurance. With the initial trials considered a successful and the impressive capabilities of the EM 710S already noted, the survey suite on HMS Endurance now features one of the most versatile multibeam echosounder systems available.

High resolution seabed mapping system

The EM 710 multibeam echosounder is a high to very high resolution seabed mapping system capable of meeting all relevant survey standards. The system configuration can be tailored to the user requirements, allowing for choice of beam widths as well as transmission modes. The minimum acquisition depth is from less than 3 meters below its transducers, and the maximum acquisition depth is up to 2000 meters. Acrosstrack coverage (swath width) is up to 5.5 times water depth or 140 degrees to a maximum of more than 2000 meters.

HMS Endurance’s mission is to patrol and survey the Antarctic and South Atlantic, maintaining very close links with the United Kingdom Hydrographic Office and the British Antarctic Survey. She normally spends up to 7 months each year on deployment and this year is due to arrive back in Portsmouth in late May, with final EM 710S multibeam echosounder performance trials planned to take place between 6th and 13th July in UK waters.
