海洋测量结果显示，广阔的南半球水层越来越咸，密度越来越高，这一转变可能向深海输送的热量比气候模型预测的要多。每年南极的夏天，融化的海冰都会向海洋发出巨大的淡水脉冲。这种季节性供应有助于维持安踏

Antarctica’s Melting Ice Has Triggered a Sudden Shift Deep in the Ocean
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 [...]
