Multibeam Advisory Committee (MAC)
The Multibeam Advisory Committee (MAC) works with vessel operators to promote consistent operation and calibration of multibeam sonars across the US Academic Fleet. In addition to ship visits, the MAC develops best practice guidelines, software tools, and cookbooks to assist vessel operators and scientists with multibeam sonar operations. MAC Resources
