Climate Records from Corals in the Central and Western Sectors of the Tropical South Pacific

题目：热带南太平洋中部和西部珊瑚的气候记录热带南太平洋地区在过去的几个世纪里，只有很少的样本用于每年解决的古气候记录。该地区气候的历史记录也相对较少。然而，该地区受到厄尔尼诺-南方涛动（ENSO）年际系统的显著影响，也可能受到年代际尺度海洋-大气变率的影响。该奖项支持对南太平洋西部和中部的斐济和拉罗汤加的世纪珊瑚核进行分析。这两个站点位于南赤道流向西流动的太平洋暖池南缘附近和南太平洋辐合带（SPCZ）区域。该项目将对这两个地点近150年的珊瑚记录进行同位素分析，以检查南太平洋环流位置的enso波段和年代际变化。

AbstractATM-9818005Wellington, Gerald M.University of HoustonTitle: Climate Record from Corals in the Central and Western Sectors of the Tropical South PacificThe tropical South Pacific region has only been sparsely sampled for annually resolved paleoclimatic records of the last several centuries. Historical records of climate in this region are also relatively sparse. This region is however dramatically effected by the interannual El Nino Southern Oscillation (ENSO) system, and possibly by decadal-scale ocean-atmosphere variability. This award supports the analysis of multicentury coral cores from Fiji and Rarotonga in the western and central sectors of the South Pacific. Both sites are positioned near the southern edge of the Pacific warm pool within the westward flowing South Equatorial Current, and in the region of the South Pacific Convergence Zone (SPCZ). This project will isotopically analyze the upper 150 years of coral record from both sites to examine ENSO-band and decadal variability in these South Pacific gyre locations.
