本项目将利用稳定同位素和两组微化石的组合,提供上新世赤道东太平洋地表水循环的详细重建。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的淡水池的条件,而这个池反过来又导致了现代赤道不对称环流。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。
英文摘要
PISIAS 9302147 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.
