The research team, in this collaborative proposal, aims to compare speleothem records, instrumental observations of the last ~100 years, and climate models to study Caribbean climate spanning the last millennium. The research team will address two foundational questions with their project, as follows: (1) What do the high-resolution Caribbean speleothem delta oxygen-18 isotope records, together with Cariaco Basin sediments, indicate about the low-frequency, Caribbean-wide hydroclimate variations during the Late Holocene? and (2) What can be learned about the large scale Atlantic-Pacific climate interactions during the late Holocene by comparing the detailed regional Caribbean hydroclimate history with other proxy records outside the region?The broader impacts involve the education and training of undergraduate and graduate students, most notable at the University of Puerto Rico. The research results on tropical hydrology could have widespread utility in the study of climate and water resources.

在这项合作提案中，该研究小组旨在比较洞穴记录、过去~100年的仪器观测和气候模型，以研究加勒比海地区过去一千年的气候。研究小组将在他们的项目中解决以下两个基础问题：(1)高分辨率加勒比海洞穴三角洲氧-18同位素记录，以及加勒比海盆地沉积物，表明了晚全新世加勒比地区的低频水文气候变化？(2)通过比较加勒比海地区详细的水文气候历史与该地区以外的其他代用记录，可以了解到晚全新世大西洋-太平洋大尺度气候相互作用的哪些信息？更广泛的影响涉及本科生和研究生的教育和培训，最显著的是在波多黎各大学。热带水文学的研究成果在气候和水资源研究中具有广泛的应用价值。
