Breakup of last glacial deep stratification in the South Pacific
CO 2 escaped from the deep Why did the concentration of atmospheric carbon dioxide rise so much and so quickly during the last deglaciation? Evidence has begun to accumulate suggesting that old, carbon-rich water accumulated at depth in the Southern Ocean, which then released its charge when Souther...
