Multibeam System: EM2040
Dates: September 12-21, 2017
We installed four Kongsberg EM2040 multibeam echo sounders on each of Rainier’s four hydrographic survey launches from September 12th through September 13th in Everett, WA. We accomplished the test and qualification of these systems on Puget Sound from September 14th through September 21st. Conditions were generally agreeable for testing with some environmental effects potentially affecting a limited set of noise tests. All systems were successfully integrated. Measured performance is in compliance with vendor specifications and is suitable for NOAA hydrographic surveys.
