项目摘要
Deep nutrient-rich waters of the Pacific Ocean rise up along the equator and provide the basis for dense populations of planktonic organisms. Their skeletons have built up over the past 50 million years to create a 600-m-thick mound of sediments. We aim to drill a series of holes through these deposits and combine them to provide a continuous record of their deposition at the equator. As the upwelling of the Pacific Ocean water is related to wind strength, these deposits carry an important record of Earth's climate. This proposal requests funding to collect geophysical data and cores to verify that these sites are safe to drill and to locate suitable sediment sections to sample. A PhD student will have the opportunity to analyse the seismic data and to develop a database of sediment layering throughout the entire central Pacific Ocean. He/she will study these data to work out how the deposits vary around hills and with effects of flowing bottom waters. He/she will study how dissolution of carbonate material has modified the sediments. The sediment samples collected here will also be analysed for signals of recent glacial-interglacial climate fluctuations.
太平洋营养丰富的深层水域沿着赤道上升,为浮游生物的密集种群提供了基础。它们的骨骼在过去的5000万年里积累起来,形成了一个600米厚的沉积物堆。我们的目标是在这些沉积物中钻出一系列孔,并将它们结合在一起,以提供它们在赤道沉积的连续记录。由于太平洋海水的上升流与风力有关,这些沉积物携带着地球气候的重要记录。该提案要求提供资金,以收集地球物理数据和岩心,以核实这些地点可以安全地进行钻探,并确定合适的沉积物区段进行采样。博士生将有机会分析地震数据,并开发整个中太平洋沉积物分层的数据库。他/她将研究这些数据,以找出山丘周围的沉积物如何变化,以及底部水流的影响。他/她将研究碳酸盐物质的溶解如何改变沉积物。这里收集的沉积物样本也将被分析,以寻找最近冰川-间冰期气候波动的信号。
