1. Develop robust, scientific calibration methods for two specific sonar systems, using new, large standard spheres and individual beam mapping. 2. Specify new scientific data output, including raw element data, and to study the effect of different pulse transmission forms to maximize the overall signal to noise ratio across the available frequency band. Prototype post-processing tools. 3. Conduct field trials ex situ experiments on controlled, schooling populations of fish inside acoustically transparent cages at Austevoll Aquaculture station, as well as at sea, coupled with echo sounder, HD video and stereo camera methods. 4. Conduct three field trial surveys, using commercial fishing vessels with purse seine on two selected fish species, and one research vessel survey on whales. |
