The soundscape of the Anthropocene ocean

Science, Journal Year: 2021, Volume and Issue: 371(6529)

Published: Feb. 4, 2021

Oceans have become substantially noisier since the Industrial Revolution. Shipping, resource exploration, and infrastructure development increased anthrophony (sounds generated by human activities), whereas biophony of biological origin) has been reduced hunting, fishing, habitat degradation. Climate change is affecting geophony (abiotic, natural sounds). Existing evidence shows that affects marine animals at multiple levels, including their behavior, physiology, and, in extreme cases, survival. This should prompt management actions to deploy existing solutions reduce noise levels ocean, thereby allowing reestablish use ocean sound as a central ecological trait healthy ocean.

An overview of fish bioacoustics and the impacts of anthropogenic sounds on fishes

Journal of Fish Biology, Journal Year: 2019, Volume and Issue: 94(5), P. 692 - 713

Published: March 13, 2019

Fishes use a variety of sensory systems to learn about their environments and communicate. Of the various senses, hearing plays particularly important role for fishes in providing information, often from great distances, all around these animals. This information is three spatial dimensions, overcoming limitations other senses such as vision, touch, taste smell. Sound used communication between fishes, mating behaviour, detection prey predators, orientation migration habitat selection. Thus, anything that interferes with ability fish detect respond biologically relevant sounds can decrease survival fitness individuals populations. Since onset Industrial Revolution, there has been growing increase noise humans put into water. These anthropogenic are wide range sources include shipping, sonars, construction activities (e.g., wind farms, harbours), trawling, dredging exploration oil gas.

Sounding the Call for a Global Library of Underwater Biological Sounds

Frontiers in Ecology and Evolution, Journal Year: 2022, Volume and Issue: 10

Published: Feb. 8, 2022

Aquatic environments encompass the world’s most extensive habitats, rich with sounds produced by a diversity of animals. Passive acoustic monitoring (PAM) is an increasingly accessible remote sensing technology that uses hydrophones to listen underwater world and represents unprecedented, non-invasive method monitor environments. This information can assist in delineation biologically important areas via detection sound-producing species or characterization ecosystem type condition, inferred from properties local soundscape. At time when worldwide biodiversity significant decline soundscapes are being altered as result anthropogenic impacts, there need document, quantify, understand biotic sound sources–potentially before they disappear. A step toward these goals development web-based, open-access platform provides: (1) reference library known unknown biological sources (by integrating expanding existing libraries around world); (2) data repository portal for annotated unannotated audio recordings single soundscapes; (3) training artificial intelligence algorithms signal classification; (4) citizen science-based application public users. Although individually, resources often met on regional taxa-specific scales, many not sustained and, collectively, enduring global database integrated has been realized. We discuss benefits such program provide, previous calls data-sharing libraries, challenges be overcome bring together bio- ecoacousticians, bioinformaticians, propagation experts, web engineers, processing specialists (e.g., intelligence) necessary support funding build sustainable scalable could address needs all contributors stakeholders into future.

Marine invertebrates and noise

Frontiers in Marine Science, Journal Year: 2023, Volume and Issue: 10

Published: March 7, 2023

Within the set of risk factors that compromise conservation marine biodiversity, one least understood concerns is noise produced by human operations at sea and from land. Many aspects how other forms energy may impact natural balance oceans are still unstudied. Substantial attention has been devoted in last decades to determine sensitivity mammals—especially cetaceans pinnipeds—and fish because they known possess hearing organs. Recent studies have revealed a wide diversity invertebrates also sensitive sounds, especially via sensory organs whose original function allow maintaining equilibrium water column sense gravity. Marine not only represent largest proportion biomass indicators ocean health but many species important socio-economic values. This review presents current scientific knowledge on invertebrate bioacoustics (sound production, reception, sensitivity), as well affected anthropogenic noises. It critically revisits literature identify gaps will frame future research investigating tolerance ecosystems.

Predicting the effects of anthropogenic noise on fish reproduction

Reviews in Fish Biology and Fisheries, Journal Year: 2020, Volume and Issue: 30(2), P. 245 - 268

Abstract Aquatic animals use and produce sound for critical life functions, including reproduction. Anthropogenic noise is recognized as a global source of environmental pollution adequate conservation management strategies are urgently needed. It becomes therefore to identify the reproductive traits that render species vulnerable acoustic disturbances, types anthropogenic most likely impact Here, we provide predictions about on fish reproduction following two-step approach: first, grouped documented effects into three mechanistic categories: stress, masking hearing-loss, test which type (continuous vs intermittent regular irregular) was significant response in each category with either meta-analysis or quantitative review, depending data availability. Second, reviewed existing literature predict would sensitive hearing-loss. In step one, concluded continuous sounds irregular amplitude and/or frequency-content (e.g. heavy ship traffic) were cause also induce From two vulnerability noise-induced stress will mainly depend on: (1) its potential reallocate more quiet times locations, (2) hearing-loss function communication behaviour. We discuss stages be based these findings. Graphic abstract

Passive acoustic monitoring as a potential tool to survey animal and ecosystem processes in freshwater environments

Freshwater Biology, Journal Year: 2019, Volume and Issue: 65(1), P. 7 - 19

Published: June 28, 2019

Abstract Biodiversity in freshwater habitats is decreasing faster than any other type of environment, mostly as a result human activities. Monitoring these losses can help guide mitigation efforts. In most studies, sampling strategies predominantly rely on collecting animal and vegetal specimens. Although techniques produce valuable data, they are invasive, time‐consuming typically permit only limited spatial temporal replication. There need for the development complementary methods. As observed ecosystems, environments host animals that emit sounds, either to communicate or by‐product their activity. The main soniferous groups amphibians, fish, macroinvertebrates (mainly Coleoptera Hemiptera, but also some Decapoda, Odonata, Trichoptera). Biophysical processes such flow sediment transport well activities within aquatic ecosystems. Such be recorded, remotely autonomously, provide information local diversity ecosystem health. Passive acoustic monitoring ( PAM ) an emerging method already deployed terrestrial uses sounds survey environments. Key advantages its non‐invasive nature, ability record autonomously over long timescales.

Over the last few decades, offshore wind energy industry has expanded its scope from turbines mounted on foundations driven into seafloor and standing in less than 60 m of water, to floating moored 120 prospecting development ~1,000 water. Since there are prototype mooring systems these deepwater, facilities (OWFs) currently deployed, their effects marine environment speculative. Using available scientific literature concerning appropriate analogs, including fixed-bottom OWFs, land-based facilities, wave tidal devices, oil gas platforms, we conducted a qualitative systematic review estimate potential environmental OWFs during operation, as well mitigation measures address some effects. We evaluated six categories effects: changes atmospheric oceanic dynamics due removal modifications, electromagnetic field species power cables, habitat alterations benthic pelagic fish invertebrate communities, underwater noise species, structural impediments wildlife, water quality. Our synthesis 89 articles selected for suggests that many could be mitigated pose low risk if developers adopt strategies best-practice protocols.
