Since commercial ships transited the sea in their tens of thousands over the past fifty years, there has been a huge increase in ambient noise in large parts of the ocean. Except when close to other ships, ship-radiated noise is primarily low-frequency (1000 Hz), and aggregate noise could be dominant in low-frequency bands even outside of shipping lanes. Such sounds could have a variety of negative effects on marine species and contribute to an already loud environment. Specifically for animals that depend on low-frequency noises, such as baleen whales, seals, and fish, this entails limiting the areas over which they can communicate. Shipping noise acknowledged as a significant issue for marine conservation by a global community of researchers, environmental organizations, governmental organizations, and sectors of the shipping industry, including the International Maritime Organization (IMO) of the United Nations. Given the nature, scope, and historical absence of regulation, it is difficult to mitigate the potential effects of aggregate vessel noise. The IMO has made progress in the formulation of recommendations for the reduction of underwater noise from commercial shipping thanks to proactive collaborations among environmentalists, regulators, scientists, and industry. The focus of this article is on marine animals as it examines low-frequency noise unintentionally radiated from ships and its potential consequences for marine life. Authors also chart the development and evolution of initiatives to address the advantages and costs of ship-quieting measures from an economic and environmental perspective. The writers are central figures in a variety of governmental, scientific, industrial, and conservation groups.
