The proposed project will study the microbialites of the post-LGM reef sequence (ca. 21-10 ka) drilled off Tahiti during IODP Expedition 310. The study of structural (LM, SEM, TEM) and geochemical and geomicrobiological (trace element ratios; stable isotopes, phosphate contents, organic carbon contents, lipid biomarkers) trends aims at unraveling the relationship between environmental change and the genesis of the microbialites that make up up to 80% of the reef succession. The ultimate goal of the project is, by combining the results from the microbialites with sea-level and sea-surface temperature data from corals (studies by other Science Party Members), to reconstruct a comprehensive picture of climatic and oceanographic changes during the post-LGM sealevel rise.

拟议的项目将研究LGM后reef序列（约21-10 ka）的微生物，在IODP探险期间在大溪地上钻了大溪地。环境变化和微生物的起源，占礁石继承的80％。该项目的最终目标是，将微生物的结果与珊瑚（其他科学党成员的研究）的海平面和海面温度数据相结合，以重建在LGM Sealevel后升高期间的气候和海洋学变化的全面情况。
