In addition to the EM 304 multibeam sonar objectives, EK60/80 split-beam echosounder objectives included acceptance of the newly installed EK80 38 kHz transducer and calibration of each frequency (18, 38, 70, 120, 200 kHz). Other mission readiness objectives included ensuring functionality of all ancillary equipment, including sound speed profiling equipment, updating and refining procedural documents, and defining new procedures for supporting shore-based processing using the Cloud. EX-21-01 collected 22,187 square kilometers of bathymetry and associated water column data, with 18,773 square kilometers being within the U.S. Exclusive Economic Zone and Territorial Sea deeper than 200 m. EX-21-01 operations will involve a transit southwestward followed by multiple equipment calibration operations that will occur in U.S. waters southwest of Florida, followed by calibration of the dynamic positioning system, and then a transit to the U.S. Blake Plateau where additional calibrations and focused mapping operations will occur, mostly in deep water (>200 m). Equipment calibration will include (but is not limited to) a GNSS Azimuth Measurement System (GAMS) test, a patch test, a speed noise test, multiple reference surveys, backscatter normalization, and EK calibrations. Remote watchstanding and integration of Cloud processing procedures will also be tested during this cruise. A Kongsberg Engineer is sailing to perform the SAT, and will provide critical DAS for troubleshooting the newly installed systems.
