基于末次盛冰期（LGM）大气CO2浓度（pCO 2）低值的实验研究，利用大气-海洋环流模式，系统地研究了海洋物理变化和生物效应对末次盛冰期（LGM）大气CO2浓度低值的影响。海洋碳循环模型的数值实验表明，pCO 2在LGM海洋中降低了约30 ppm。大部分pCO 2的减少被解释为CO2溶解度的变化，由于较低的海表温度（SST）在LGM期间的海洋。此外，我们发现，SST的变化在高纬度北方大西洋可以解释超过三分之一的整体变化引起的全球SST变化的pCO 2，这表明劳伦特冰盖和pCO 2之间的重要反馈。
Based on LGM experiments with an atmosphere–ocean general circulation model, we systematically investigated the effects of physical changes in the ocean and induced biological effects as well on the low atmospheric CO2concentration (pCO2) at the last glacial maximum (LGM). Numerical experiments with an oceanic carbon-cycle model showed that pCO2was lowered by ~30 ppm in the LGM ocean. Most of the pCO2reduction was explained by the change in CO2solubility in the ocean due to lower sea surface temperature (SST) during the LGM. Moreover, we found that SST changes in the high-latitude Northern Atlantic could explain more than one-third of the overall change in pCO2induced by global SST change, suggesting an important feedback between the Laurentide ice sheet and pCO2.
