This project will acquire seismic data and piston cores to support IODP proposal 626, which focuses on Cenozoic climate change as elucidated by a paleo-Equatorial transect in the Pacific. The research is collaborative with a NERC UK-IODP to researchers at Cardiff University and University of Southampton. The proposed work focuses on the identification of drillsites through standard marine seismic surveying with a short streamer, integration of seismic reflection data with existing data, interpolation of important stratigraphic interfaces over large regions of the Pacific, and inversion of data to constrain equatorial Pacific biogenic sedimentation during the Oligocene and Miocene transitions. Broader impacts include fostering of international collaboration on an IODP site survey project and inclusion of undergraduates in shipboard and shorebased research.

该项目将获取地震数据和活塞岩心，以支持IODP提案626，该提案侧重于太平洋古赤道样带所阐明的新生代气候变化。该研究是与NERC UK-IODP合作进行的，研究人员来自卡迪夫大学和南安普顿大学。建议的工作重点是通过短拖缆标准海洋地震测量确定钻探点，将地震反射数据与现有数据整合，在太平洋大片地区插值重要的地层界面，以及反演数据以约束渐新世和中新世过渡期间赤道太平洋的生物沉积。更广泛的影响包括促进IODP现场调查项目的国际合作，并将本科生纳入船上和岸上研究。
