Background information and definitions
Some subtidal benthic invertebrate species rely on sound to communicate, feed, navigate, detect predators, and reproduce (Popper & Hawkins 2012). Underwater noise, for instance from shipping, fishing, construction work, or aggregate extraction can mask the ambient soundscape and negatively affect subtidal benthic invertebrate species that rely on it (de Soto 2016; Pine et al. 2012; Popper & Hawkins 2012). Reducing underwater noise, for instance by limiting the level, intensity, and duration of specific noise-generating activities, or by using ‘technologies’ to dampen underwater noise emissions (such as bubble curtains, hydro-sound dampeners), may prevent the negative effects on subtidal benthic invertebrates.
Evidence for interventions related to noise pollution from sonars are summarised under “Threat: Pollution – Limit, cease or prohibit the use of sonars”.
