Impacts of sea level rise on atmospheric CO2 concentrations during glacial - de-glacial periods.

地球科学中最未得到解答的问题之一与冰河时代前工业化大气中二氧化碳浓度大幅下降的原因有关。在过去的80万年里，地球气候在冰期(冰期)和间冰期之间循环。在这些周期中，全球气温和大气二氧化碳的变化之间存在着非常诱人的相关性。关于这一差异的原因，已经提出了一些建议。在这里，你将使用最先进的地球系统模型来测试这样一种观点，即在间冰期期间，大陆周围浅海的增加在调节冰期-间冰期大气二氧化碳浓度方面发挥了重要作用。你的学习将在英国班戈大学和美国俄勒冈州立大学之间进行，由Tom Rippeth和Mattias Green(在班戈)和Andreas Schmittner(俄勒冈)指导。

One of the great under-answered questions in the geosciences relates to the cause of the big drop in the concentration of CO2 in the preindustrial atmosphere during ice ages. Over the past 800 thousand years the Earth climate has cycled between ice ages (glacial periods) and interglacial periods. Over these cycles there is a very enticing correlation between the global temperature and the variations in atmospheric CO2. A number of proposals have been put forward as to the cause of this variation. Here you will use a state-of-the-art Earth System model to test the idea that the increased presence of the shallow seas around the continents during interglacial periods played a significant role in the mediation of atmospheric CO2 concentration over glacial - interglacial periods. Your studies will be split between Bangor University, UK and Oregon State University, USA, and supervised by Tom Rippeth and Mattias Green (at Bangor) and Andreas Schmittner (Oregon).
