Illustration depicting the North Icelandic Jet current

The newly confirmed North Icelandic Jet forms when the warm surface of the North Icelandic Irminger Current sheds eddies that cool and disperse within the Iceland Sea Gyre. Cold, dense waters leak out to form the North Icelandic Jet. The jet feeds cold, dense water into the Deep Western Boundary Current, helping to drive the lower limb of the Ocean Conveyor, the global ocean circulation system that regulates Earth’s climate.
