Kongsberg Mesotech’s M3 Bathy System, an entry-level survey system for shallow-water bathymetric applications, is now officially designated compliant with IHO S-44, a reference standard for companies engaged in hydrographic surveying, marine engineering or nautical charting.
The IHO compliance consists of various criteria including vertical accuracy and target detection standards. In order to assess IHO-S44 compliance, these criteria were tested during an experiment performed by the Ocean Mapping Group at the University of New Brunswick.
During the testing, which took place in February 2014, bathymetry data from the M3 was collected in depths ranging from 15 – 40m. The test targets were a series of standard concrete 1m cubes laid along 20m and 40m contours.
The results confirmed that the M3 Bathy is capable of achieving bathymetric survey data that meets two orders of IHO standards.
The core of the M3 Bathy is Kongsberg Mesotech’s M3 Series MultiMode Multibeam Sonar. The M3 Sonar is the only instrument in its price point that produces high-quality imaging records and 3D profiling point cloud data using the same sonar head.
