A silent ocean
Jan 17, 2023, 08:48 PM
The Southern Ocean is one of the last pristine areas of the world’s oceans. Only few fishing and research ships venture into the Southern Ocean (with tourist vessels sailing primairly along its northern perimeter along the Antarctic peninsula and adjacent island chain) and commercial exploitatation of Antarctic natural resources is currently (still) prohibited under the Antarctic Treaty. Hence few anthropogenic acoustic sources exist in this region while the sea ice cover absorps sound more efficiently than the open water surface, reducing ambient sound levels further.
