Antarctic ice-sheet response to atmospheric CO2 and insolation in the Middle Miocene
Antarctic ice-sheet Middle Miocene atmospheric CO2
2009/12/3
Foraminiferal oxygen isotopes from deep-sea sediment cores suggest that a rapid expansion of the Antarctic ice sheet took place in the Middle Miocene around 13.9 million years ago. The origin for thi...
Glacial-interglacial atmospheric CO2 change：a possible “standing volume” effect on deep-ocean carbon sequestration
Glacial-interglacial deep-ocean carbon atmospheric CO2 change
2009/12/3
So far, the exploration of possible mechanisms for glacial atmospheric CO2 drawdown and marine carbon sequestration has tended to focus on dynamic or kinetic processes (i.e. variable mixing-, equilibr...
