Ocean measurements show a vast Southern Hemisphere water layer growing saltier and denser, a shift that could send more heat into deep waters than climate models predict. Every Antarctic summer, melting sea ice sends a vast pulse of fresh water into the ocean. That seasonal supply helps sustain Antarctic Intermediate Water (AAIW), a layer of
