“…Fish sounds and hearing abilities (for species without auditory specializations) are largely below 1000 Hz (Popper and Fay, 2011;Tricas and Boyle, 2014). The frequency overlap with vessel noise could result in masking of sounds vital to reproduction, feeding and territorial defense (Ladich, 2013), adding another stressor on these already impacted reefs (Figure 8).…”

Human activity is contributing increasing noise to marine ecosystems. Recent studies have examined the effects of boat noise on marine fishes, but there is limited understanding of the prevalence of this sound source. This investigation tracks vessel noise on three reefs in the US Virgin Islands National Park over four months in 2013. Ambient noise levels ranged from 106-129 dB rms re 1 µPa (100 Hz -20 kHz). Boat noise occurred in 6-12% of samples. In the presence of boat noise, ambient noise in a low-frequency band (100-1000 Hz) increased by >7 dB above baseline levels and sound levels were significantly higher. The frequency with the most acoustic energy shifted to a significantly lower frequency when boat noise was present during the day.These results indicate the prevalence of boat noise and its overlap with reef organism sound production, raising concern for the communication abilities of these animals.

“…Most fishes without specialized morphological adaptations cannot hear frequencies higher than around 1000 Hz (Popper and Fay, 2011), and the majority of fish calls are often below 1000 Hz (Tricas and Boyle, 2014). Thus, low-frequency sounds Figure 2.8: Power spectral density at (A) 500 Hz and (B) 5 kHz for 3 reefs from the entire long-term deployment period.…”

“…Striped parrotfish (Scarus iserti) spawn in groups of 5-30 individuals, and sound production occurs during the spawning rush, in which the parrotfish swim upward rapidly en masse (Lobel, 1992). Sound production abilities are indeed common among fishes; for example, soniferous behaviors have been characterized for 45 species in 12 families of Hawaiian reef fish, representing just shy of half of the total number of species surveyed (Tricas and Boyle, 2014).…”

“…Fish survey data were pooled across transects and summarized by species and size classes. Whether a species was soniferous or not was assessed by comparing these results to a previously published list of soniferous Hawaiian reef fish (Tricas and Boyle, 2014). Analyses were carried out in MATLAB 9.1 (MathWorks, Natick, MA).…”

“…These bands were chosen based on published frequency ranges of the majority of fish calls (Tricas and Boyle, 2014) and snapping shrimp sounds (Au and Banks, 1998). SPL was only calculated for DSG recordings from the same recording period as the DMONs and only for the DMON MF recordings, in order to match the DSG hydrophone frequency response more closely.…”

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.
