Acidification of the world’s oceans from rising atmospheric carbon dioxide levels reduces the availability of carbonate required by some marine organisms to build shells and skeletons, and potentially affects their ability to maintain existing structures.
We don’t clearly understand the ecological effects of commerical toothfish fishing in the Ross Sea region. To improve our knowledge, we conducted a survey of demersal (bottom-dwelling) fish species on the Ross Sea slope - particularly grenadiers and icefish - during the 2015 Antarctic Ecosystems Voyage.
The Southern Ocean is under-sampled. Data collected continuously during the Antarctic Ecosystems Voyagehelped fill an important knowledge gap about oceanographic and atmospheric processes in this important region.
