摘要:本提案要求支持研究晚古近纪和新近纪北太平洋热带辐合带的风力演化和发展与迁移。该研究将利用热带和亚热带太平洋一系列海洋岩心中的颗粒大小、同位素数据和粉尘成分来追踪渐新世到近代的风力和粉尘来源(亚洲或美洲)。该项目的目标是确定纬向风强度的演变,并追踪热带辐合带的发展和迁移。此外,该研究将更好地约束美洲沙尘组分的来源,并确定太平洋盆地亚洲源沙尘与美洲源沙尘相变化的纬度变化。
英文摘要
Summary: This proposal request support to study evolution of wind strength and development and migration of the Intertropical Convergence Zone in the North Pacific Ocean during the late Paleogene and Neogene. The study will use grain size, isotope data and composition of dust in a series of marine cores in the tropical and subtropical Pacific to trace wind strength and dust source (Asian or American) during the Oligocene to Recent. The goals of the project are to determine the evolution of strength of zonal winds, and to trace the development and migration of the Intertropical Convergence Zone through time. In addition the study will better constrain the provenance of the American dust component and determine the changes in the latitude of the facies change between Asian-source and American source dust in the Pacific Basin.
