NOAA Ship Pisces Cruise PC-11-06 (14) Multibeam Sonar Workshop on NOAA Ship Pisces (EK60)
The overall objective is to familiarize participating scientists with PISCES multibeam echosounder (Simrad ME70) configuration, operation, calibration and data collection and test the sonar's capabilities for a variety of applications. An additional objective is to collect water column and seafloor scattering data using PISCES multibeam echosounder and splitbeam echosounders (Simrad EK60) in coordination with measurements being conducted on OKEANOS EXPLORER using Simrad EM302 multibeam echosounder for comparison between systems.

|Purpose||1) Review ME70 configuration options, performance consequences of configuration choices, calibration procedures, and methods of synchronizing ME70 with other acoustic systems for simultaneous operation. 2) Collect acoustic scattering data from schools of fish for school size and shape analysis. 3) Collect acoustic scattering data from individual fish for spectral and directivity estimation. 4) Collect acoustic scattering data from the seabed to estimate bottom roughness and bottom type characterization and to compare with OKEANOS EXPLORER EM302 echosounder data at the same survey location. 5) Collect data using ME70 and EK60 echosounders from same water column targets as EM302 echosounder on OKEANOS EXPLORER. These targets will be both biological constituents of the offshore Deep Scattering Layer as well as gas bubbles released from natural gas seeps. 6) Calibrate ME70 in each configuration used for data collection.|
