A hidden sea current , discovered far below the ocean ’s aerofoil near Iceland , could be a major role player in the ocean ’s reaction to climate change , a new sketch hint .
The current , called the North Icelandic Jet , contributes to a key component of a circulation pattern bang as the " great ocean conveyor belt . " This circulation rule delight warm surface water system to high latitude where the water system warms the strain , then cools , sinks and returns toward the equator as a abstruse , cold urine menstruum .

" We ’ve identified a Modern paradigm " that has " important ramification " for the sea circulation ’s wallop on the mood , said report team penis Robert Pickart of the Woods Hole Oceanographic Institution in Massachusetts .
Scientists have been concerned that the elephantine conveyer belt is slowing down due to worldwide warming . As Arctic sea ice vanishes , more refreshful weewee is predicted to run into the northerly North Atlantic , where it could freeze and decrease the motive for the conveyor belt to deliver as much warm water as it does now . If theconveyor belt slows downenough , the Northern Hemisphere could become colder in the future .
But that might not happen if the North Icelandic Jet is as big a contributor to the overall ocean flow as the study suggest .

To further enquire the Modern current , a squad of scientists from the United States , Iceland , Norway and the Netherlands are schedule to embark today ( Aug. 22 ) on a sail aboard the enquiry vessel Knorr . The cruise will be chronicle at theNorth Icelandic Jet Cruise website .
The study was published in yesterday ’s ( Aug. 21 ) online issue of the diary Nature Geoscience .
The research vessel Knorr navigates the Iceland Sea while taking measurements of the Jet.
