This grant supports the participation of UK scientists Professor Paul Pearson in Expedition 363 of the International Ocean Discovery Program which plans to study the history of the 'Indo-Pacific Warm Pool' over the last 15 million years. It includes costs to cover his time while on board ship (2 months at sea) and post-expedition scientific study.Sea surface temperatures exceed 28oC across a huge area of the tropical western Pacific and Indian Oceans. Known as the Indo-Pacific Warm Pool (IPWP), this area is fundamental to the global atmospheric circulation and hydrologic cycle. The IPWP is intensifying with global warming, but modelling its likely future is challenging. Expedition n363 aims to study its temperature and climatic history over the past 15 million years, including through glacial to interglacial climate cycles and back to the globally warm Miocene epoch. Understanding its past history will help determine if its current temperature is near to its likely maximum or if global warming can cause much greater intensification in the future.Professor Pearson is a specialist in the study of microscopic fossils called planktonic foraminifera. He will study the evolution of the ocean plankton in the region over the study period, in relation to climatic change and sea level fluctuations which greatly affect the distribution of land masses and shallow seas and hence ocean current patterns. The foraminifera are also used to determine the age of the sediments drilled (called biostratigraphy) and providing other expedition scientists with a high quality planktonic foraminifer biostratigraphy will be one of the main features of this project. In additional there is a particular focus on an evolutionary lineage of foraminifera called Pulleniatina which has considerable untapped potential for stratigraphic work and also as a case study in the detailed speciation and extinction of a group of plankton. Study of this group will be facilitated by the large populations and varying morphology exhibited by them and because, like snails, they can be left or right handed and the pattern of coiling through time and across space is highly complex and potentially very informative.

该赠款支持英国科学家保罗·皮尔森（Paul Pearson）教授参与国际海洋发现计划的探险363，该计划计划在过去的1500万年中研究“印度太平洋暖游泳池”的历史。它包括在船上（海上2个月）和外部科学研究的时间内支付他的时间的费用。在热带西太平洋和印度洋的大片地区，SEA表面温度超过28oC。该区域被称为印度太平洋暖池（IPWP），是全球大气循环和水文周期的基础。 IPWP随着全球变暖而加剧，但是对其可能的未来进行建模是具有挑战性的。 Expedition N363旨在研究过去1500万年的温度和气候历史，包括通过冰川到冰川间气候周期，然后回到全球温暖的中新世时期。了解其过去的历史将有助于确定其当前温度是否接近其最高可能性，或者全球变暖是否会在将来引起更大的强化。Pearson是研究称为浮游有孔虫的微观化石研究的专家。他将在研究期间研究该地区海洋浮游生物的演变，这与气候变化和海平面波动有关，这极大地影响了土地质量和浅海的分布，从而极大地影响了海洋电流模式。有孔虫还用于确定钻探沉积物的年龄（称为生物地层学），并为其他探险科学家提供高质量的浮游有孔虫生物地层学，这将是该项目的主要特征之一。另外，特别着重于称为紫杉原的有孔虫的进化谱系，该谱系具有较大的地层工作潜力，也是一组浮游生物的详细形成和灭绝的案例研究。对这一组的研究将受到他们所展示的大量人群和各种形态的促进，因为像蜗牛一样，它们可以左手或右手，并且在时间和跨太空中盘绕的模式非常复杂，并且潜在的信息非常有用。
