This proposal is funded to survey and core high accumulation Holocene sediments along the margin of Columbia and Peru in the northeastern tropical Pacific. This should allow for a high-resolution reconstruction of sea surface temperatures and salinity by using the oxygen isotopic composition and Mg/Ca ratios of planktonic foraminifera, and continental climate proxies such as clay mineralogy. By doing the proposed work a number of unresolved questions about ENSO-type variability may be answered.

本研究旨在对热带太平洋东北部哥伦比亚和秘鲁沿岸的全新世高堆积沉积物进行调查和取芯。通过利用浮游有孔虫的氧同位素组成和Mg/Ca比值，以及大陆气候代用物（如粘土矿物学），这将允许对海面温度和盐度进行高分辨率重建。通过完成提出的工作，许多关于enso型变率的未解决问题可能得到解答。
