Lloyd, Steve Lepper, Paul Pomeroy, Simon Evaluation of UAVs as an underwater acoustics sensor deployment platform Marine surveys carried out by Passive Acoustic Monitors conventionally use towed hydrophone arrays, which requires dedicated surface observation boats. This is a costly and slow process, which could be made cheaper and quicker by using Unmanned Aerial Vehicles (UAVs). Presented in this paper are the initial findings from using UAVs to capture underwater acoustic signals from an acoustic test tank. untagged;Mechanical Engineering not elsewhere classified 2016-12-15
