Collaborative Research: P2C2--Hydrological Variability during the Last Millennium from High Resolution Proxies

在这项合作提案中，研究小组的目标是比较洞穴沉积物记录、过去100年的仪器观测和气候模型，以研究加勒比海上个千年的气候。 研究小组将解决两个基本问题，他们的项目，如下：（1）高分辨率加勒比洞穴三角洲氧-18同位素记录，连同Cariaco盆地沉积物，表明低频，加勒比地区的水文气候变化在晚全新世？（2）通过比较加勒比海区域水文气候的详细历史与该区域以外的其他代用记录，可以了解到全新世晚期大尺度南极-太平洋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，最显著的是波多黎各大学。 热带水文学的研究成果可广泛用于气候和水资源研究。

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.
