Kongsberg M3 Sonar Part of New Fisheries Monitoring System

The M3 Sonar® (Multimode Multibeam Sonar) from Kongsberg Mesotech, is now part of a new acoustic transponder tag monitoring system being introduced to the fisheries research community during the American Fisheries Society annual conference in Portland, Oregon.

This system is the result of engineering cooperation between Kongsberg Mesotech and Sonotronics, with application support from Milne Technologies.

The system is composed of three instruments: The M3 Sonar® and M3 Tag Activator, and Sonotronic’s acoustic transponder tags.

The transponder tags are inserted into targets and remain dormant until the M3 Tag Activator wakes them. Once operational, the M3 Sonar® collects data from the tag including the unique tag code, position and in some cases, depth of the tagged target, while also sampling a large swath for water column targets and bottom habitat.

This enables fisheries researchers to easily identify one fish from among hundreds. Additional benefits of the system include the ability to be used in conjunction with other acoustic tools to provide biomass estimates and the opportunity for extended multi-year studies due to the transponder tags’ longer battery life, Kongsberg explained.

This new system is a reflection of Kongsberg Mesotech’s continued advancement into environmental monitoring applications for the M3 Sonar®. We are excited to introduce a new capability to the environmental monitoring market based on our established technology integrated with leading solutions from Sonotronics and Milne Technologies, which meet the needs of many different fishery research applications,” said Jeff Condiotty, Fisheries Research Manager, Kongsberg Maritime.
