EM304 Water Column Sonar Data Collected During EX2101

Description

Between April 14 and May 10, 2021 EX-21-01 performed the sea
acceptance testing of the newly installed Kongsberg EM 304 MKII transmit array,
conducted mission readiness of the mapping systems through annual testing and
calibration, and mapped unexplored areas of the Blake Plateau. 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.
