This proposal seeks funding to statistically analyze the long (~278 m) sediment record of the Chew Bahir basin, as part of the ICDP-funded Hominin Sites and Paleolakes Drilling Project (HSPDP). The aim of the project is (1) to establish a robust age-depth model for the sediment cores, (2) to correlate the Chew Bahir record with other records within and outside HSPDP, (3) to detect trends, rhythms and events in the environmental record of the basin, and (4) identify recurrent, characteristic types of climate transitions in the time series, as compared with the ones of the other HSPDP sites and climate records outside HSPDP. This task is handled by a doctoral student, who will work in a team of specialists in the field of mathematical geosciences at the University of Potsdam and the Potsdam Institute for Climate Impact Research, but will benefit also from the larger Chew Bahir and HSPDP projects. The Doctoral Student, expected to be trained as an earth scientists with a pronounced fascination with mathematical methods, will use linear techniques to establish an age model and to detect climate shifts and cycles. He/she is expected to understand the sediment and proxy forming processes in the basin as well as he/she is expected to be equipped with solid knowledge in statistics and programming. He/she will use nonlinear methods to detect more complex or hidden processes within the data. The results of the project will help to illuminate the role of climate change (timing, nature, abruptness, magnitude, and synchronicity of these shifts especially the transitions between Glacial and Interglacial) in the evolution of mammalian (including hominin taxa) during the Pleistocene.

该提案寻求资金来统计地分析Chew Bahir盆地的长（〜278 m）沉积物记录，这是ICDP资助的人类站点和古生物钻探项目（HSPDP）的一部分。该项目的目的是（1）为沉积物芯建立一个强大的年龄深度模型，（2）将Chew Bahir的记录与HSPDP内外的其他记录相关联，（3）以检测趋势，节奏和事件的盆地环境记录和事件，以及（4）与气候的经常性，SPER的特征类型和（4）相比，与之相比，与之相比。 HSPDP。这项任务由一名博士生处理，他将在波茨坦大学和波茨坦气候影响研究所的数学地球科学领域的专家团队中工作，但也将从较大的Chew Bahir和HSPDP项目中受益。这位博士生预计将作为地球科学家培训，对数学方法的迷恋，将使用线性技术来建立年龄模型并检测气候变化和周期。预计他/她将了解盆地中的沉积物和代理过程，以及他/她有望在统计和编程方面具有可靠的知识。他/她将使用非线性方法检测数据中更复杂或隐藏的过程。该项目的结果将有助于阐明气候变化的作用（这些转移的时机，性质，突然，突然，大小和同步性，尤其是冰川和冰川间之间的转变）在开发期间哺乳动物（包括人类分类群）的演变中。
