MOORE 9302487 This project will use stable isotopes and assemblages of two groups of microfossils to provide a detailed reconstruction of surface water circulation in the eastern equatorial Pacific through the Pliocene. The authors hypothesize that closing of the Isthmus of Panama led to conditions which created the warm fresh pool of water observed in the area today, and that the pool in turn is responsible for the modern equatorially-asymmetric circulation. They hope to determine the relationship of these events to the increase of northern hemisphere glaciation documented elsewhere.

MOORE 9302487 该项目将使用稳定同位素和两组微化石组合来详细重建赤道东太平洋至上新世的地表水循环。作者假设，巴拿马地峡的关闭导致了今天在该地区观察到的温暖淡水池的形成，而该池又是现代赤道不对称环流的原因。他们希望确定这些事件与其他地方记录的北半球冰川作用增加之间的关系。
