Arctic warming has thinned springtime sea ice across the Arctic Ocean. A new study shows that this alters the chemistry of the atmosphere near the Earth’s surface and may increase the amount of toxic mercury contaminating the region.
The potent greenhouse gas methane is seeping out of parts of the Arctic Ocean, and the discovery may represent another cycle contributing to climate warming in the region.
A recent mission marked the completion of a five-year collaboration between the United States and Canada to survey the Arctic Ocean. The bilateral project collected scientific data to delineate the continental shelf beyond 200 nautical miles from the coastline, also known as the extended continental shelf (ECS).
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.
