Abstract:
The shallow-water survey with the dive safari vessel was performed with a boomer-plate AA301 (Applied Acoustic) as acoustic source operated with a power of 300 J/shot, a 24-channel MicroEel analog streamer (Geometrics), and a global positioning system (Hemisphere, Canada). Shot intervals was 1.2 s and the applied recording length 0.2 s TWT. Profiling speed was 3 to 3.5 knots.
