A Coral-based Reconstruction and Analysis of Subdecadal- to Multidecadal-scale Climate Variability in the Cuban Sector of the Tropical North Atlantic/Caribbean Sea

研究所将在古巴海岸外钻取珊瑚岩心，以建立古气候记录（d18 O、Sr/Ca、放射性碳）。 通过这些记录，他们将解决与该地区过去200年来气候变化的性质及其对热带以外的北大西洋和北美的影响有关的问题。随着可用于校准最近珊瑚测量的十年尺度海洋表面温度仪器记录的可用性，自然气候变化的记录可以有效地延长到过去。该项目还将包含一个建模组件，以更定量地评估古气候重建。包括两个具体目标：1）加勒比/热带大西洋和北美大陆气候之间的古气候学和古风暴学联系; 2）南赤道大西洋和北亚热带大西洋表面沃茨的贡献的变化，这两者共同决定了佛罗里达流的密度特性。

The PIs will drill coral cores off the coast of Cuba to construct paleoclimate records (d18O, Sr/Ca, radiocarbon). With these records they will address questions related to the nature of climate variability in the region over the past 200 year, and its impact on extra-tropical North Atlantic and North America. With the availability of decadal scale instrumental sea surface temperature records that can be used to calibrate recent coral measurements, the record of natural climatic variability can be effectively extended in to the past. The project will also contain a modeling component to more quantitatively assess paleoclimatic reconstructions. Two specific objectives are included: 1) Paleoclimatology and paleotempestology links between climate in the Caribbean/ Tropical Atlantic and continental North America; and 2) Variability in the contribution of South Equatorial Atlantic and North Subtropical Atlantic surface waters, which together determine the density properties of the Florida Current.
