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.

研究人员的目标是从墨西哥西南部厄尔尼诺南方涛动 (ENSO) 敏感地区收集的铀系列定年石笋中，开发过去五千年来的几项高分辨率（约 2 至 5 年）、时间重叠和复制的 δ 氧 18 同位素记录。 该项目的目标是检验这样的假设：墨西哥南部在中世纪气候异常 (MCA) 期间经历了长期潮湿的条件，这一时期与东太平洋类似拉尼娜现象的低海面温度状态同时发生。主要的更广泛的影响包括博士生的教育以及为美国和墨西哥感兴趣的公众编写英语和西班牙语的洞穴科学指南。 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。
