Collaborative Research: P2C2--Paleoclimate and Cultural Change in Mesoamerica: Testing the Hypothesis of ENSO Forcing of Late Holocene Rainfall Variability

研究人员的目标是开发几个高分辨率（约2至5年），时间重叠和复制的三角洲氧-18同位素记录在过去的五千年里，从铀系列石笋收集在厄尔尼诺南方涛动（ENSO）墨西哥西南部敏感地区。 该项目的目标是检验这样一种假设，即墨西哥南部在中世纪气候异常（MCA）期间经历了长时间的潮湿条件，这与拉尼娜现象更为一致。主要的广泛影响涉及博士生的教育以及为感兴趣的公众成员编写洞穴科学的英语和西班牙语指南，美国和墨西哥。 此外，科学成果可以广泛应用于物理和社会科学的许多领域。

The researchers aim to develop several high-resolution (~2 to 5 year), time-overlapping and replicated delta oxygen-18 isotope records over the past five millennia from uranium series dated stalagmites collected in an El Nino-Southern Oscillation (ENSO) sensitive region of southwestern Mexico. The goal of the project is to test the hypothesis that southern Mexico experienced prolonged wet conditions during the Medieval Climatic Anomaly (MCA) that was coincident with a more La Niña-like state of low sea surface temperatures in the eastern Pacific Ocean.The primary broader impacts involve the education of a doctoral student and the development of English and Spanish guides to cave science for interested members of the public in the U.S. and in Mexico. Also, the science results could have broad application to many areas in the physical and social sciences.
