“…This study demonstrated that the continental shelf environment off NE Taiwan was heavily influenced by sounds generated from shipping and fishing activities. Frequently occurring anthropogenic noise can interfere with the communication, prey detection, predator avoidance, reproduction, and habitat selection of marine organisms [ 58 , 59 ]. As ocean noise continues to increase, noise-induced physiological and behavioral impacts may be observed more frequently.…”

Remote acquisition of information on ecosystem dynamics is essential for conservation management, especially for the deep ocean. Soundscape offers unique opportunities to study the behavior of soniferous marine animals and their interactions with various noise-generating activities at a fine temporal resolution. However, the retrieval of soundscape information remains challenging owing to limitations in audio analysis techniques that are effective in the face of highly variable interfering sources. This study investigated the application of a seafloor acoustic observatory as a long-term platform for observing marine ecosystem dynamics through audio source separation. A source separation model based on the assumption of source-specific periodicity was used to factorize time-frequency representations of long-duration underwater recordings. With minimal supervision, the model learned to discriminate source-specific spectral features and prove to be effective in the separation of sounds made by cetaceans, soniferous fish, and abiotic sources from the deep-water soundscapes off northeastern Taiwan. Results revealed phenological differences among the sound sources and identified diurnal and seasonal interactions between cetaceans and soniferous fish. The application of clustering to source separation results generated a database featuring the diversity of soundscapes and revealed a compositional shift in clusters of cetacean vocalizations and fish choruses during diurnal and seasonal cycles. The source separation model enables the transformation of single-channel audio into multiple channels encoding the dynamics of biophony, geophony, and anthropophony, which are essential for characterizing the community of soniferous animals, quality of acoustic habitat, and their interactions. Our results demonstrated the application of source separation could facilitate acoustic diversity assessment, which is a crucial task in soundscape-based ecosystem monitoring. Future implementation of soundscape information retrieval in long-term marine observation networks will lead to the use of soundscapes as a new tool for conservation management in an increasingly noisy ocean.

“…Shipping activity such as shing is a major contributor to noise pollution in waters 7,8 . This has been evident in several studies, which prove that ships produce lowfrequency noise with varying intensity [9][10][11][12][13][14][15] . The other sources are contributed by another anthropological activities [16][17][18][19] , marine biota [20][21][22][23][24][25][26] , and physical processes [27][28][29] .…”

“…Previous studies on aquatic biota (see [9][10][11][12][13][14][15] shows the existence of a traditional shing boat in the waters of Cilacap should be managed in such a way that the available resources remain sustainable. Several countries and regions have formulated regulations regarding the limits of noise which allowed for shipping making operating vessels to comply with these regulations.…”

As the main contributor to noise pollution in Cilacap waters, the noise characteristics of traditional fishing boats based on distance are very important to be studied. This research aimed to determine noise intensity and frequency based on the distance for each traditional fishing boat (3, 5, and 10 GT). The results showed that these boats emitting noise with broadband frequency and receive levels reached 153 dB re 1 μPa. The noise characteristics were different for each type of ship due to differences in the size, engine type, and operational speed. The receive level had the same decreased pattern based on the distance for each noise frequency, but with a different intensity. Meanwhile, the noise frequency had increased quadratically based on the distance, where the higher frequency, the greater change so that the noise was not detected faster.

“…Coral larvae may be attracted toward near‐shore areas hosting diverse reef organisms for settlement, and demonstrate positive responses to different cues including acoustic signals of a healthy reef consisting of fish calls and grunts, and that of snapping shrimps (Dixson, Abrego, & Hay, ; Lecchini et al, ; Vermeij et al, ). The Suva Harbour municipal site is directly exposed to ranging magnitudes of noise pollution from large ships and small boats from the adjacent major Suva Port, floating dry docks, the Suva Yacht Club, and drilling and construction noises from the nearby industrial area.…”

A relic inshore reef ecosystem adjacent to the Fijian capital of Suva and another remote inshore reef were monitored monthly from July 2014 to July 2015 for coral recruitment, sedimentation rates, coral cover, temperature, and light intensity. Despite a major sewage spill in Suva Harbour in December 2014, the municipal inshore site exposed to constant anthropogenic activity, recorded no significant differences in coral spat abundance (except for the family Poritidae) on artificial substrata compared to the remote inshore site. Total yearly spat abundance was 106 on municipal reef and 132 on remote reef, while average daily sediment trap collection rates (g cm2/day) were significantly higher in the municipal site for the entire duration of monitoring. Total annual particulate organic matter content in sediment was also significantly higher in the municipal site (107.51 g cm2), compared to the remote site (43.37 g cm2). Mean light intensity was significantly lower for the municipal site (69.81 lum/ft2) compared to the remote site (239.26 lum/ft2), with Photosynthetically Active Radiation also lower for the former (800–1,066.66 µmol m−2 s−1) compared to the latter (3,266.66–3,600 µmol m−2 s−1). The lack of significant differences in coral spat recruitment rates suggests that settling larvae may be unable to distinguish between sub‐optimal and optimal sites probably as a consequence of interference with coral settlement cues arising from anthropogenic development.
