Abstract:
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.
