This complex circulation system in the Arctic—which impacts the entire food web—is in a delicate balance. In recent years, scientists have documented changes in the Arctic system, including a dramtatic reduction in sea ice cover and a weakening of the Beaufort Gyre circulation system, that are attributed to climate change. The Arctic Ocean affects the way of life of not only the Arctic native peoples, but also those of us living “downstream,” in Europe and North America. As such, the Arctic Ocean, and the effect of changes that are taking place there, are the focus of intense study by oceanographers of all disciplines.

Scientists discover that the amount of heat in a major Arctic Ocean circulation system has doubled over the past 30 years. If the temperatures continue to spike, it could eventually spell trouble for the ice above.
Researchers at Woods Hole Oceanographic Institution developed a new communication and navigation system that works over long distances under Arctic sea ice, allowing scientists to use autonomous underwater vehicles to explore the ice-covered Arctic Ocean.
The climate in the Arctic region once predictably shifted back and forth between two regimes. But now the system seems to be stuck.
Greenlanders are well away of piteraqs, the hazardous torrents of cold air that sweep down off the ice cap. But scientists are just beginning to unravel how and when piteraqs form.
