The phonic footprint of marine tourism : exploring the underwater sound levels of whale watching and cruise vessels travelling within Skjálfandi Bay, Iceland
Marine noise pollution is known to have detrimental impacts on marine species and ecosystems, and one of the dominant sources is vessel traffic, made worse by its rapid global expansion. These trends hold true for Icelandic waters as well, with boat-based tourism becoming especially prolific with gr...
