Stellwgen Bank国家海洋保护区位于美国人口稠密的东北海岸附近的马萨诸塞湾；随后，该地区的海洋居民暴露在高水平的人为水下声音中，特别是由于商业航运。本研究调查了具有商业和生态重要性的大西洋鳕鱼(Gadus Morhua)和黑线鳕(Melanogrammus Aeglefinus)种群在三个产卵地点估计有效交流空间的变化。在三个月的录音期间，通过球形传播模型估计的环境声压级和估计的有效发声半径都发生了剧烈波动。声压级的增加似乎在很大程度上是由大型血管活动推动的，因此，与三个地点中的两个地点的自动识别系统跟踪的血管数量呈显著正相关。在发声活动频繁的时候，在这些记录地点观察到的几乎持续的高水平低频声音和相应的通信空间的减少引起了人们的严重关切，即在关键的生物学时期，同种生物之间的通信可能会受到损害。这项研究初步评估了这些动物的交流空间以及这些空间因人为水声而发生的变化。
Stellwagen Bank National Marine Sanctuary is located in Massachusetts Bay off the densely populated northeast coast of the United States; subsequently, the marine inhabitants of the area are exposed to elevated levels of anthropogenic underwater sound, particularly due to commercial shipping. The current study investigated the alteration of estimated effective communication spaces at three spawning locations for populations of the commercially and ecologically important fishes, Atlantic cod (Gadus morhua) and haddock (Melanogrammus aeglefinus). Both the ambient sound pressure levels and the estimated effective vocalization radii, estimated through spherical spreading models, fluctuated dramatically during the three-month recording periods. Increases in sound pressure level appeared to be largely driven by large vessel activity, and accordingly exhibited a significant positive correlation with the number of Automatic Identification System tracked vessels at the two of the three sites. The near constant high levels of low frequency sound and consequential reduction in the communication space observed at these recording sites during times of high vocalization activity raises significant concerns that communication between conspecifics may be compromised during critical biological periods. This study takes the first steps in evaluating these animals’ communication spaces and alteration of these spaces due to anthropogenic underwater sound.
