This flow of deep water is formed as surface waters in the region cool, releasing heat to the atmosphere, becoming colder and denser. Scientists have long suspected that warming in in the Arctic and North Atlantic could disrupt the formation of this deep water formation, causing the AMOC to change or weaken and cause significant changes to regional and global climate patterns. “Where and how dense water is formed in the Nordic Seas is likely to change in a warming climate,” said Huang. Funding for these studies was provided by the US National Science Foundation under grants OCE-1558742, OCE-1259618, OCE-1558742, and OCE-1259618. We play a leading role in ocean observation, and operate the most extensive suite of data-gathering platforms in the world.
