Objective

Using the ME70 and ER60s to observe a large number of small pelagic fish schools, under a range of environmental conditions (continental slope, inshore zone, Gironde river plume). Characterizing the environment of small pelagic schools. The abiotic environment will be characterized with CTD profiles and the biotic environment of small pelagics (scattering layers made up of zooplankton and micronecton prey) will be characterized using acoustic data collected by the ME70 and ER60s as well as mesopelagic trawling. An acoustic zooplankton profiler (TAPS) will also be used during the CTD profiles. Automatically identifying the major taxonomic groups in the scattering layers based on multifrequency acoustic data will be tested. The discriminating power of the the ME70's frequency band will be compared to that of combining the single frequency ER60s. The related project was Ifremer ObsHal.
