为了更好地了解挪威沿海鳕鱼（Gadus morhua）的产卵发声，在2019年春季的一项实验中，以固定垂直和拖曳水平模式部署了一个原型八元相干水听器阵列，以监测鳕鱼的声音。鳕鱼聚集的深度分布监测同时与超声波回声测深仪。分析记录在水听器阵列上的鳕鱼发声，以提供时频特性，并在校正从鳕鱼位置到水听器阵列的单向传输损耗后提供源级分布。记录到的鳕鱼发声频率范围为1620 ~ 600 Hz，峰值功率频率为1660 Hz，平均持续时间为300 ms，平均声源强度为163.5 ± 7.9 dB re 1 μPa。接收到的鳕鱼发声率的空间依赖性估计使用水听器阵列的测量，因为该阵列是从较深的周围沃茨水平拖曳到浅水入口区的实验场地。水深依赖的概率检测区域鳕鱼发声量化，并发现显着减少浅水区的入口。我们表明，拖曳水听器阵列部署从一个移动的船只是非常宝贵的，因为它可以调查鳕鱼发声活动在多个位置，提供连续的空间覆盖，是互补的固定传感器系统，提供连续的时间覆盖在一个给定的位置。
To better understand spawning vocalizations of Norwegian coastal cod (Gadus morhua), a prototype eight-element coherent hydrophone array was deployed in stationary vertical and towed horizontal modes to monitor cod sounds during an experiment in spring 2019. Depth distribution of cod aggregations was monitored concurrently with an ultrasonic echosounder. Cod vocalizations recorded on the hydrophone array are analysed to provide time–frequency characteristics, and source level distribution after correcting for one-way transmission losses from cod locations to the hydrophone array. The recorded cod vocalization frequencies range from ∼20 to 600 Hz with a peak power frequency of ∼60 Hz, average duration of 300 ms, and mean source level of 163.5 ± 7.9 dB re 1 μPa at 1 m. Spatial dependence of received cod vocalization rates is estimated using hydrophone array measurements as the array is towed horizontally from deeper surrounding waters to shallow water inlet areas of the experimental site. The bathymetric-dependent probability of detection regions for cod vocalizations are quantified and are found to be significantly reduced in shallow-water areas of the inlet. We show that the towable hydrophone array deployed from a moving vessel is invaluable because it can survey cod vocalization activity at multiple locations, providing continuous spatial coverage that is complementary to fixed sensor systems that provide continuous temporal coverage at a given location.
