“…There are several studies showing a range of effects of motorboat sound on marine animals (Holles, Simpson, Radford, Berten, & Lecchini, 2013; Nedelec et al., 2014; Simpson et al., 2016). For example, killer whales (Foote et al., 2006), humpback whales, (Risch, Corkeron, Ellison, & Van Parijs, 2012), and common dolphins (May‐Collado & Wartzok, 2008) have been shown to shift their call characteristics out of the frequency bands motorboat sound dominates as well as increasing sound levels (Foote, Osborne, & Hoelzel, 2004; Scheifele et al., 2005).…”

Human‐generated sound affects hearing, movement, and communication in both aquatic and terrestrial animals, but direct natural underwater behavioral observations are lacking. Baited underwater video (BUV) were deployed in near shore waters adjacent to Goat Island in the Cape Rodney–Okakari Point Marine Reserve (protected) or outside the reserve approximately four km south in Mathesons Bay (open), New Zealand to determine the natural behavior of Australian snapper Pagrus auratus exposed to motorboat sound. BUVs worked effectively at bringing fish into video range to assess the effects of sound. The snapper inhabiting the protected area showed no behavioral response to motorboat transits; however, fish in the open zones either scattered from the video frame or decreased feeding activity during boat presence. Our study suggests that motorboat sound, a common source of anthropogenic activity in the marine environment can affect fish behavior differently depending on the status of their habitat (protected versus open).

“…While others have compared acoustic parameters to biophysical variables 52 such as coral cover, fish density, and sea state across several reefs (Nedelec et al 2014;Bertucci 53 et al 2016), this has often come with the trade-off of using relatively brief recordings that likely 54 overlook the appreciable variation in sound cues over longer timescales (Radford et al 2008; 55 Staaterman et al 2014; . 56…”

Acoustic and biological trends on coral reefs off Maui, Hawaii

et al. 2017

13Coral reefs are characterized by high biodiversity and evidence suggests that reef soundscapes 14 reflect local species assemblages. To investigate how sounds produced on a given reef relate to 15 abiotic and biotic parameters and how that relationship may change over time, an observational 16 study was conducted between September 2014 and January 2016 at seven Hawaiian reefs that 17 varied in coral cover, rugosity, and fish assemblages. The reefs were equipped with temperature 18 loggers and acoustic recording devices that recorded on a 10% duty cycle. Benthic and fish 19 visual survey data were collected four times over the course of the study. On average, reefs 20 ranged from 0 to 80% live coral cover, although changes between surveys were noted, in 21 particular during the major El Niño-related bleaching event of October 2015. Acoustic analyses 22 focused on two frequency bands (50-1200 Hz and 1.8-20.5 kHz) that corresponded to the 23 dominant spectral features of the major sound-producing taxa on these reefs, fish and snapping 24 shrimp, respectively. In the low-frequency band, the presence of humpback whales (December-25 May) was a major contributor to sound level, whereas in the high-frequency band sound level 26 closely tracked water temperature. On shorter timescales, the magnitude of the diel trend in 27 sound production was greater than that of the lunar trend, but both varied in strength among 28 reefs, which may reflect differences in the species assemblages present. Results indicated that the 29 magnitude of the diel trend was related to fish densities at low frequencies and coral cover at 30 high frequencies; however, the strength of these relationships varied by season. Thus, long-term 31 acoustic recordings capture the substantial acoustic variability present in coral-reef ecosystems 32 and provide insight into the presence and relative abundance of sound-producing organisms. 33 34

“…North Atlantic right whales (Eubalaena glacialis) have been shown to call louder in the presence of elevated background noise (Parks et al, 2011). Vessel noise may affect embryonic development and increase mortality in sea hares (Stylocheilus striatus) (Nedelec et al, 2014). Temporary hearing threshold shifts after exposure to noise have been documented in aquatic fauna from goldfish (Carassius auratus) (Smith et al, 2004) to harbor seals (Phoca vitulina) (Kastak et al, 1999) and bottlenose dolphins (Tursiops truncatus) (Nachtigall et al, 2004).…”

Coral reef soundscapes : spatiotemporal variability and links to species assemblages

Coral reefs are biodiverse ecosystems that are at risk of degradation as a result of environmental changes. Reefs are constantly in a state of flux: the resident species assemblages vary considerably in space and time. However, the drivers of this variability are poorly understood. Tracking these changes and studying how coral reefs respond to natural and anthropogenic disturbance can be challenging and costly, particularly for reefs that are located in remote areas. Because many reef animals produce and use sound, recording the ambient soundscape of a reef might be one way to efficiently study these habitats from afar. In this thesis, I develop and apply a suite of acoustics-based tools to characterize the biological and anthropogenic acoustic activity that largely comprises marine soundscapes. First, I investigate links between reef fauna and reef-specific acoustic signatures on coral reefs located in the U.S. Virgin Islands. Second, I compare those findings to a more expansive study that I conducted in Maui, Hawaii, in which the drivers of bioacoustic differences among reefs are explored. Third, I investigate the distances over which sounds of biological origin may travel away from the reef and consider the range within which these acoustic cues might be usable by pelagic larvae in search of a suitable adult habitat. Fourth, I assess the extent to which the presence of vessel noise in shallow-water habitats changes the ambient soundscape. Finally, I present the results of a modeling exercise that questions how ocean noise levels might change over the next two decades as a result of major projected increases in the number and size of and distance traveled by commercial ships. The acoustics-based tools presented here help provide insight into ecosystem function and the extent of human activity in a given habitat. Additionally, these tools can be used to inform an effective regulatory regime to improve coral reef ecosystem management.
