了解南极冰冻圈从始新世-渐新世过渡期（~33 Ma）开始到新生代气候变化的重要时期的演变和动态，不仅具有重大的科学意义，而且对社会也非常重要。从温室地球到冰屋地球的转变可以想象是大规模行星变化中最重要的一步，影响了全球海平面，珊瑚礁，海洋学和生物进化等变化。最先进的气候模型结合古气候代用数据表明，南极冰川最初开始和发展的主要触发机制是大气中二氧化碳浓度的下降。由于目前大气中温室气体不断增加，导致全球气温迅速上升，极地气候研究，特别是南极冰冻圈的行为，在研究议程上占有突出地位。钻探南极威尔克斯陆缘的目的是提供一个长期的记录，从沉积档案沿着海岸到近海样带，南极冰川及其与全球气候和海洋变化的密切关系。地层学解释表明，威尔克斯地记录将包括在新生代地球气候演变的关键时期，当冰冻圈形成，可能在逐步的方式，并随后演变到承担其今天的配置。通过我的研究，我将帮助解决研究探险的一些基本目标：1。对第一层冰筏碎片的研究将告诉我们冰第一次到达威尔克斯地边缘的时间和性质。2.对过去3400万年来冰筏碎片的研究将告诉我们，早期波动的东南极冰盖如何转变为更稳定的东南极冰盖。它还将阐明在气候变暖时期冰稳定性的重要方面。3.对过去3 400万年南大洋海水化学的研究将进一步告诉我们南极冰盖的形成如何影响世界海洋这一重要部分的海洋化学。将这一点与冰盖的范围、盛行的大陆风化和海洋的生产力联系起来，将有助于我们发展气候系统中的主要联系。

Understanding the evolution and dynamics of the Antarctic cryosphere, from its inception during the Eocene-Oligocene transition (~33 Ma) through the significant periods of climate change during the Cenozoic, is not only of major scientific interest but also is of great importance for society. The transition from Greenhouse to Icehouse Earth conceivably was the most significant step in large-scale planetary change, impacting global sea level, albedo, and oceanographic and biotic evolution, among other changes. State-of-the-art climate models combined with paleoclimatic proxy data suggest that the main triggering mechanism for initial inception and development of the Antarctic glaciation was the decreasing levels of CO2 concentration in the atmosphere. With current rising atmospheric greenhouse gases resulting in rapidly rising global temperatures, studies of polar climate, and the Antarctic cryosphere behaviour in particular, are prominent on the research agenda. Drilling the Antarctic Wilkes Land margin is designed to provide a long-term record, obtained from sedimentary archives along an inshore to offshore transect, of Antarctic glaciation and its intimate relationships with global climatic and oceanographic change. Stratigraphic interpretations indicate that the Wilkes Land record will include the critical periods in Cenozoic Earth climate evolution when the cryosphere formed, likely in step-wise fashion, and subsequently evolved to assume its present-day configuration. With my research I will help to tackle some of the fundamental goals of the research expedition: 1. The study of the first layer of ice-rafted debris will tell us about the timing and nature of the first arrival of ice at the Wilkes Land margin. 2. The study of ice-rafted debris over the past 34 million years will tell us about the transition of a fluctuating early East Antarctic ice sheet into a more stable East Antarctic ice sheet. It will also shed light on the important aspect of ice stability in times of warmer climatic periods. 3. The study of the seawater chemistry in the Southern Ocean over the past 34 million years will furthermore tell us how the build-up of the Antarctic ice sheet influenced ocean chemistry in this important part of the world's ocean. Linking this back to the extent of the ice sheet, prevailing continental weathering, and productivity in the ocean, will help us develop major links in the climate system.
