MR1 is portable, and can be deployed by the Hawaii Mapping Research Group from research or survey vessels anywhere in the world. With acoustic imagery swaths up to 25 km wide and a survey speed of 9 knots, MR1 can image up to 415 square kilometers per hour. MR1 simultaneously acquires digital bathymetry (swath width ~ 3.4 times water depth) and sidescan sonar imagery (swath width ~ 7.5 times water depth). The MR1 towfish uses separate transducer arrays on its port and starboard sides, which operate at different frequencies (11 and 12 kHz, respectively) to minimize crosstalk. </gco:CharacterString> </gmi:description> </gmi:MI_Instrument>
