Funding is requested to conduct a high resolution study of late Pleistocene and Holocene ocean temperature and hydrographic variability archived in deep sea cores collected in 1998 within the Indo-Pacific warm pool region as part of the international paleoceanographic project IMAGES. This project will produce the first records of climate variability in the tropical warm pool region at resolutions high enough for direct comparison with both high and low latitude ice core records. This will allow testing of the hypothesis that the warm pool did not cool more than 2 degrees C during the last glacial. A Multiproxy (staple isotope, alkenone, Mg/CA) approach will be used to reconstruct sea surface temperatures, as well as deep and intermediate water temperatures for the last 150kyr.

作为国际古海洋学项目 IMAGES 的一部分，需要资金对 1998 年在印度-太平洋暖池区域收集的深海岩心存档的更新世晚期和全新世海洋温度和水文变化进行高分辨率研究。 该项目将以足够高的分辨率产生热带暖池地区气候变化的第一批记录，以便与高纬度和低纬度冰芯记录进行直接比较。 这将可以检验以下假设：在末次冰河期间，温水池的降温幅度不会超过 2 摄氏度。 多代理（主要同位素、烯酮、Mg/CA）方法将用于重建海面温度以及过去 150kyr 的深层和中层水温。
