RV Investigator Voyage IN2015_E03 Profiling Acoustic and Optical System (pAOS) (DRAFT)

This record describes data from the Profiling Acoustic and Optical System (pAOS) collected on the Marine National Facility RV Investigator voyage IN2015_E03 Titled: Acoustics and pelagic ecosystems, testing equipment, developing procedures and sample collection, departing Hobart on the 16th April and returning to Hobart on the 23rd April, 2015.

Profiling Acoustic and Optical System (pAOS) also known as Profiling Lagrangian Acoustic and Optical System (pLAOS) is a multibeam acoustics platform used for pelagic biomass studies. The system is equipped with several transducer frequencies (38kHz, 120kHz, and 333kHz), a downward looking video camera, and a downward and oblique digital stills. The system is deployed using the coring boom and allowed to free-fall from the surface to the desired depth to collect data.
