Collaborative Research: A Paleogene Equatorial Pacific Transect

9633802摩尔这些来自密歇根大学和爱达荷州博伊西州立大学的研究人员将在东太平洋进行一次研究邮轮，以调查古近纪期间详细的气候和海洋条件，与现代相比，这是一个全球异常温暖的时期。他们将研究穿越古近纪赤道的N-S断面沉积的沉积物，以确定风生粘土和粉砂的来源(北美和亚洲)，这将为热带间会聚带在古代大气中的位置提供直接证据。他们还将检查沉积物中的化石以评估海洋条件，这些数据将被用来约束全球温暖的始新世温室条件的模型。除了这些研究课题外，在这次巡航中收集的地震反射和沉积物岩心数据将用于指导未来深海钻探的特定地点的选择，以便在拟议的D/V JOIDES决议巡航上更详细地研究这一问题，该船为一个由国家科学基金会通过NSF海洋钻探计划协调的国际成员国财团进行深海钻探。***

9633802 Moore These investigators from University of Michigan and Boise State University in Idaho will undertake a research cruise in the eastern Pacific Ocean to investigate detailed climatic and oceanographic conditions during the Paleogene period, a time of exceptional worldwide warmth compared to modern times. They will examine sediments deposited in a N-S transect across the Paleogene equator to determine the source (North America vs Asia) of wind-borne clay and silt, which will provide direct evidence of the location of the Inter-Tropical Convergence Zone in the ancient atmosphere. They will also examine fossils in the sediments to evaluate oceanographic conditions, and these data will be used to constrain models of the "Eocene hot house" conditions of worldwide warmth. In addition to these research topics, the seismic reflection and sediment core data collected during this cruise will be used to guide selection of specific sites for future deep ocean drilling to study this problem in more detail on a proposed cruise of D/V JOIDES Resolution, a vessel which conducts deep-ocean drilling for an international consortium of member nations coordinated by the National Science Foundation through the NSF Ocean Drilling Program. ***
