Autonomous Surveillance of Marine Mammal Populations in South AfricaMarine mammal activity and behaviour is greatly affected by human activity and environmental changes. It is therefore important for their conservation that they are observed and monitored, ideally across a large span of both time and area. Underwater passive acoustic sensors, possibly aided by above-water visual or thermal sensors, are intended to be used for this purpose. The aim is to develop a system whereby a body of water can be monitored and acoustic sources corresponding to marine mammal vocalisations and anthropogenic activity from within this area can be automatically mapped and tracked. The proposed methodology involves the use of two arrays of hydrophones, deployed statically in a body of water. The data from these will be processed with advanced beamforming techniques for a novel, persistent, wide-area solution, with the potential for increased robustness through data fusion with other sensors.

南非海洋哺乳动物种群的自主监测海洋哺乳动物的活动和行为很大程度上受到人类活动和环境变化的影响。因此，对它们进行观察和监测对于它们的保护非常重要，最好是在大范围的时间和区域内进行观察和监测。水下无源声学传感器可能辅以水上视觉或热传感器，旨在用于此目的。其目的是开发一种系统，通过该系统可以监测水体，并可以自动绘制和跟踪与海洋哺乳动物发声和该区域内的人类活动相对应的声源。所提出的方法涉及使用静态部署在水体中的两个水听器阵列。来自这些数据的数据将使用先进的波束成形技术进行处理，以形成一种新颖的、持久的、广域的解决方案，并有可能通过与其他传感器的数据融合来提高鲁棒性。
