Marine noise is a form of ocean pollution that may affect fauna ranging from tiny zooplankton to enormous whales. It may interfere with their acoustic sensing of the ocean environment and communication; disrupt behaviour and displace animals; unbalance energy demand and uptake; in extreme cases, cause injury and trauma; and ultimately impact health and survival. The Southern Ocean is not immune to marine noise and its impacts; however, very few studies on bioacoustic impacts have been undertaken on Antarctic species in the Southern Ocean. Here, we present an overview of sources of marine noise in the Southern Ocean, its potential impacts, mitigation options, as well as management and research needs.
