Summary of measurements |
- -Acoustic calibration of the shipboard echosounders (38 kHz, 120 kHz, 12 kHz,
37.5 kHz). -Testing the performance of the OSSIAN 2500 (deep) echosounder, compared to the OSSIAN 1500/38 kHz and OSSIAN 500/12 kHz sounders. -Pelagic trawling (76x70) with acquisition of data on the trawl's shape, stress and strain at various points on the fishing gear and the trawl's position with respect to the vessel. -Archiving of sonar images for later processing. -Continuing to develop the SABRINA system for real time analysis of radiated noise from the vessel: acquisition of reference curves for different engine power for the vessel or different acoustic equipment. -Various trials and tests for version 2 of the MOVIES+ software to process echosounder data: EK500 data acquisition, simultaneous acquisition of 3 different frequencies. -Trials and tests of the vessel's software programs to prepare the BAHIA cruise: TS-Archiv, S_DIV, VIDOP, CASINO, MOVIES+, FISHVIEW, RAPTRI and PUPITRI. -Trials for the SEABIRD SBE 19 CTD, particularly when equipped with a Chelsea Mini-track fluorometer.
