Last glacial maximum/last deglacial South Pacific interannual to decadal climate variability - Sub-seasonal reconstructions from Tahiti reef corals

我们建议开放的时间窗口，年际到年代际气候变率在南太平洋最后一次冰川最大期和最后一次冰消期，通过分析大溪地的珊瑚礁化石。这些珊瑚是在IODP第310次考察（2005年10月至11月）期间发现的，这是欧洲海洋研究钻探联合会（ECORD）执行的一项使命特定平台考察。科学党的成员之一是托马斯费利斯。个别珊瑚生长持续超过100年！我们计划产生亚季节性解决重建的温度和水文平衡的变化在海面上的时间间隔在21至10 kyr前，根据氧同位素和Sr/Ca的变化在珊瑚骨骼。这项研究将提供独特的见解大气/海洋变化的自然模式的动力学，如厄尔尼诺南方涛动和太平洋十年期涛动，在不同的边界条件下，从今天，并解决了国际海洋发展方案远征310的一个主要科学目标。将这种基于珊瑚的重建与最先进的气候模型模拟进行比较，可能有助于评估未来温室效应预测的有效性。

We suggest opening time-windows of interannual to decadal climate variability in the South Pacific during the last gfacial maximum and the last deglaciation, by analysing fossil reef corals from Tahiti. The corals have been recovered during IODP Expedition 310 (October- November 2005), a Mission Specific Platform Expedition implemented by the European Consortium for Ocean Research Drilling (ECORD). A member of the science party is Thomas Felis. Individual corals grew continuously for periods of >100 years! We plan to generate subseasonally resolved reconstructions of changes in both temperature and hydrologic balance at the sea surface during time intervals between 21 to 10 kyr ago, based on oxygen isotope and Sr/Ca variations in coral skeletons. This study will provide unique insights into the dynamics of natural modes of atmosphere/ocean variability, such as the El Nino-Southern Oscillation and the Pacific Decadal Oscillation, under boundary conditions different from today, and addresses a major scientific objective of IODP Expedition 310. Comparing such coral based reconstructions with state-of-the-art climate model simulations might help to assess the validity of future greenhouse projections.
