Supporting passage from source
The Antarctic Intermediate Water (AAIW)—a vast layer of fresh water spanning much of the Southern Hemisphere's ocean—has rapidly reversed its long-term trends in salinity and density, according to new research. The AAIW helps store carbon, supply oxygen and drive global ocean currents.
