Collaborative Research: Recent Climate Variability in the Western Indian Ocean and East Africa: Exploring the Potential of Isotopic Records in Kenyan Corals

题目：西印度洋和东非的近期气候变率：探索肯尼亚珊瑚同位素记录的潜力SGER奖支持对肯尼亚珊瑚礁珊瑚核的收集和地球化学分析。在这个地区，季风驱动着海面洋流的季节性逆转。与之相关的热带辐合带（ITCZ）的运动、解体和改造导致每年有两个雨季。该地区海洋大气的年际至年代际变化（如风、降雨、地表流和温度、温跃层深度）与大尺度气候系统密切相关，特别是印度季风和厄尔尼诺/南方涛动。珊瑚地球化学记录有可能以接近每月的分辨率记录过去几个世纪的这种变化。本项目将探讨开发这种长期记录的可行性。

Abstract ATM-9409779 Dunbar, Robert B. William Marsh Rice University Title: Recent Climate Variability in the Western Indian Ocean and East Africa: Exploring the Potential of Isotopic Records in Kenyan Corals This SGER award supports the collection and geochemical analysis of coral cores from the reefs of Kenya. In this region, monsoon winds drive seasonal reversals in surface ocean currents. The associated movement, breakup, and reformation of the Intertropical Convergence Zone (ITCZ) imposes two rainy seasons each year. Interannual to decadal changes in the ocean-atmosphere of this region (e.g. winds, rainfall, surface currents and temperature, thermocline depth) relate closely to large-scale climate systems, notably the Indian monsoon and the El Nino/Southern Oscillation. Coral geochemical records have the potential to document such variability over the past several centuries with near-monthly resolution. This project will explore the feasibility of developing such long-term records.
