R2 Sonic Multibeam Echosounder
The School of Surveying manages a 2026 R2 Sonic Multibeam Echosounder on behalf of users in departments across the University of Otago. Our multibeam echosounder can collect depth, seabed intensity and watercolumn data.
For information please visit: https://oceanexplorer.noaa.gov/explorations/09bermuda/background/multibeam/multibeam.html
The equipment is available for teaching and research when accompanied by a trained University of Otago user. It is also available for commercial hire – for commercial hire enquiries or more information please contact Emily Tidey.

MBES System Mounting Options
The equipment can be fitted to existing over-the-side poles on many University vessels: https://www.otago.ac.nz/marinescience/about/facilities/researchvessels.html#
The current mounting configurations include the vessels R/V Polaris II and R/V Beryl Brewin, and a custom made pontoon for towing or attaching to the side of smaller craft. These three vessels have offsets determined to streamline mobilisation and get you measuring as fast as possible. We can also send flange details if you wish to manufacture your own mount.
University of Otago users need to have a trained operator with the equipment and an account created by Marine Science so that they can book the gear using the Marine Science Fieldwork and Resources Planning tool found at https://www.otago.ac.nz/msfrp
Important: When booking you must allow time for set-up and demobilisation. We recommend you consult the booking calendar and work with adjacent bookings as much as possible.
Before hire you will be asked to sign a User Agreement and fill out a Collection Plan. It is anticipated that data collected with this equipment will become publicly available, after a suitable research interval so it is vital that complete metadata be recorded and stored with the original data. On return you need to fill out a Hiring Period Completion Form to aid billing.
University research and teaching internal hire prices for 2018 are: $250/day in use, $50/day for setup and standby. These are reviewed annually.
Commercial hire is managed separately and handled by university contracting procedures. Door-to-door insurance must be provided. Equipment requirements will be discussed on a case by case basis. Early contact is recommended.
