Atlantic Current Weakening Observed Over Two Decades
Recent research published in Science Advances highlights a significant decline in the Atlantic Meridional Overturning Circulation (AMOC) over the past two decades. This study, conducted by scientists from the U.S., UK, and Canada, utilized direct ocean measurements rather than relying solely on computer models. The AMOC is a crucial system of ocean currents that plays a vital role in redistributing heat, salt, and nutrients across the Atlantic, significantly influencing the climate of regions such as Europe. The research involved data collection from four deep-ocean monitoring sites, using mooring arrays anchored along the western Atlantic from the Caribbean to Eastern Canada. These arrays measured ocean-bottom pressure and other properties below 1,000 meters, revealing a consistent decline in deep western overturning transport across the studied latitudes.
