“…In contrast, about 1 in 6 of all vessel transits, or 16%, were identified as being ‘noisy’. Although our classification of vessels in this category was a subjective one, this preliminary result is worth consideration given that noise is a specific component of vessel disturbance in aquatic systems [ 45 ], and marine birds may respond to noise as a disturbance [ 35 , 36 , 46 ]. While effects of vessel noise alone has so far not been well studied in the context of waterbird responses [ 3 ], it has been explicitly described as a supposed component of overall vessel disturbance effects (e.g., [ 7 , 47 , 48 ]).…”

“…We identified vessels as noisy based on apparent in-air noise, but some vessels will contribute to both in-air and underwater noise (with the latter unmeasured by us in this study). Effects of underwater noise on birds are perhaps even more poorly understood than are those of in-air noise [ 46 , 49 ], but are likely have both direct and indirect consequences.…”

The coastal waters of southern British Columbia, Canada, encompass habitat of international conservation significance to coastal and marine birds, including sizeable areas designated in the early 1900s as Migratory Bird Sanctuaries (MBS) to protect overwintering waterfowl from hunting near urban centres. Two of these, Shoal Harbour (SHMBS) and Victoria Harbour (VHMBS), have seen significant marine infrastructure development in recent decades and experience considerable vessel traffic. Vessel-related stressors are known to affect waterbirds, but traffic characteristics in coastal urban areas are poorly understood for the smaller vessels not tracked by Automatic Identification Systems (AIS). We conducted a pilot study using shore-based observers to develop small-vessel baselines for the winter months, when regional waterbird numbers are highest. During our surveys we recorded considerable inter-site variability in vessel traffic characteristics, with one site (SHMBS) a source of nearly twice as many vessel transits as the other (VHMBS). Most recorded vessels were small watercraft (mean length 26 ± 17′, mode 18′), and vessels at the high-traffic site were both shorter and faster on average. One in six vessels were classified as ‘noisy’, of interest given that noise is an important component of vessel disturbance of waterbirds and other marine animals. Few vessels (7% of all recorded) were of the type required to carry AIS transponders, which highlights the monitoring gap created by using AIS-based approaches alone in nearshore waters, and allows for correction of AIS-derived vessel counts. Waterbird community composition also varied by locality, with one site dominated by gulls (Laridae), cormorants (Phalacrocoracidae), and seaducks (Tribe Mergini), and the other by gulls, cormorants, and alcids (Alcidae). Our results demonstrate that fine-scale local variability must be taken into account when managing for vessel traffic disturbance of waterbirds, particularly at sites of high human population density and increasing coastal development.

“…The rise in ambient noise is a growing concern due to the adverse effects on marine life, in particular on marine mammals (Southall et al, 2008(Southall et al, , 2019Richardson et al, 2013), invertebrates (Murchy et al, 2019), fishes (Slabbekoorn et al, 2010;Popper et al, 2014;Cox et al, 2018) and birds (Anderson Hansen et al, 2020). Impacts are pervasive and affect individual animals as well as populations (Pirotta et al, 2018;Soudijn et al, 2020), at all taxonomic and trophic levels.…”

The present and future contribution of ships to the underwater soundscape

Since the industrial revolution the ocean has become noisier. The global increase in shipping is one of the main contributors to this. In some regions, shipping contributed to an increase in ambient noise of several decibels, especially at low frequencies (10 to 100 Hz). Such an increase can have a substantial negative impact on fish, invertebrates, marine mammals and birds interfering with key life functions (e.g. foraging, mating, resting, etc.). Consequently, engineers are investigating ways to reduce the noise emitted by vessels when designing new ships. At the same time, since the industrial revolution (starting around 1760) greenhouse gas emissions have increased the atmospheric carbon dioxide fraction x(CO2) by more than 100 μmol mol-1. The ocean uptake of approximately one third of the emitted CO2 decreased the average global surface ocean pH from 8.21 to 8.10. This decrease is modifying sound propagation, especially sound absorption at the frequencies affected by shipping noise lower than 10 kHz, making the future ocean potentially noisier. There are also other climate change effects that may influence sound propagation. Sea surface warming might alter the depth of the deep sound speed channel, ice melting could locally decrease salinity and more frequent storms and higher wind speed alter the depth of the thermocline. In particular, modification of the sound speed profile can lead to the appearance of new ducts making specific depths noisier. In addition, ice melting and the increase in seawater temperature will open new shipping routes at the poles increasing anthropogenic noise in these regions. This review aims to discuss parameters that might change in the coming decades, focusing on the contribution of shipping, climate change and economic and technical developments to the future underwater soundscape in the ocean. Examples are given, contrasting the open ocean and the shallow seas. Apart from the changes in sound propagation, this review will also discuss the effects of water quality on ship-radiated noise with a focus on propeller cavitation noise.

“…Recent studies have investigated the impacts of anthropogenic noise on a wide range of taxa and across a variety of scales (Barber et al, 2009; Morley et al, 2014; Normandeau Associates, 2012; Slabbekoorn et al, 2010; Thomsen et al, 2021; Tyack, 2008). Anthropogenic noiseee can cause a range of physical, physiological, and behavioural disorders in aquatic organisms, including marine mammals (Erbe et al, 2018; Moore et al, 2012; Southall et al, 2008), seabirds (Bermúdez-Cuamatzin et al, 2018; Green et al, 2016; Hansen et al, 2020), reptiles (Injaian et al, 2020; Simmons and Narins, 2018), fish (Hastings and Popper, 2005; Hawkins, 1986; Mills et al, 2020; Popper et al, 2003), and invertebrates (Carroll et al, 2017; Coquereau et al, 2016; Murchy et al, 2019). Because of the high propagation rate and low attenuation over large distances in underwater environments, acoustic stimuli play an important role in aquatic environments (Tyack, 1998; Popper and Hastings, 2009; Slabbekoorn et al, 2010).…”

Anthropogenic sound is currently recognized as a source of environmental pollution in terrestrial and aquatic habitats. Elevated sound levels may cause a broad range of impacts on aquatic organisms among taxa. Sound is an important sensory stimulus for aquatic organisms and it may cause fluctuations in stress-related physiological indices and in a broader extent induce behavioural effects such as driving as a distracting stimulus, masking important relevant acoustic signals and cues in a range of marine and freshwater species. However, sound exposure may also induce changes in swimming activities, feed efficiency and productivity of available food sources in fish. Here, we experimentally tested sound effects on swimming activities and foraging performance in thirty adult Zebrafish (Danio rerio) individually in captivity. We used adult zebrafish and water flea (Daphnia magna) as model predator prey, respectively. We also used four sound treatments with different temporal patterns (all in the same frequency range and moderate exposure level). Our results constitute strong evidence for clear sound-related effects on zebrafish behaviour. All sound treatments induced a significant increase in the number of startle response, brief and prolonged swimming speed for zebrafish (P<0.05). Zebrafish reached to the baseline swimming speed after 60 seconds in all treatments. We found partially brief and prolonged sound effects on spatial distribution of zebrafish; Although we did not find any significant sound-related behavioural changes for horizontal spatial displacement in all treatments (P>0.05), zebrafish swam significantly more in the lower layer of the fish tank except irregular intermittent 1:1-7 in brief sound exposure (P<0.05). The results of foraging performance showed that food discrimination error was low for the zebrafish and unaffected by sound treatments (P>0.05). However, food handling error was affected by sound treatments; all treatments caused a rise in handling error (P<0.001). This study highlights the impact of sound on zebrafish swimming activities, and that more attacks are needed to consume the same number of prey items under noisy conditions.
