Late Quaternary variability of surface-water characteristics and terrigenous input in the (sub-) polar North and South Pacific: A biomarker approach

北太平洋和南太平洋(亚)极地表水特征和陆源输入的晚第四纪变化:生物标记方法

基本信息

项目摘要

As outlined in the New Application, overall goal is the reconstruction of the variability of and linkages between surface-water characteristics and terrigenous (dust) input in the (sub-) polar North and South Pacific and their relationship to global climate change, using organicgeochemical proxies. Primary targets of the proposed study are: (1) sea-surface temperature reconstruction based on alkenones (Uk 37), (2) reconstruction of sea-ice cover based on highly-branched isoprenoids (HBIs, IP25), (3) reconstruction of productivity using specific biomarkers (alkenones, sterols - especially brassicasterol and dinosterol, short-chain nalkanes) and flux rates of marine organic carbon (OC), and (4) input of terrigenous OC using long-chain n-alkanes, sterols (campesterol, ß-sitosterol) and flux rates of terrigenous OC. The biomarker records will be related to micropaleontological (diatoms, dinoflagellates, etc.) and mineralogical (quartz, feldspars, etc.) paleoenvironment proxies obtained within other BIPOMAC subprojects on the sediment cores as well as dust/Fe and CO2 records from Greenland and Antarctic ice cores. Together with the other BIPOMAC subprojects, the results of this study will significantly increase our knowledge on (sub-) polar South and North Pacific climate variability, zonal and inter-hemispheric teleconnections, as well as the role of the High Latitudes in driving and amplifying global climate variability. During the SONNE Expediton “INOPEX” carried out in July/August 2009, a major milestone of this project, unique core matrial has been recovered which more or less guarantee the success of the planned studies.
正如新申请中所概述的,总体目标是利用有机地球化学代用指标,重建(次)极地北太平洋和南太平洋地表水特征和陆源(尘埃)输入之间的变异性和联系及其与全球气候变化的关系。拟议研究的主要目标是:(1)基于烯酮的海面温度重建(UK 37),(2)基于高度支化的类异戊二烯的海冰覆盖重建(HBIs,IP 25),(3)使用特定生物标志物重建生产力(烯酮、甾醇--特别是菜子甾醇和地甾醇、短链正烷烃)和海洋有机碳(OC)的通量率,(4)长链烷烃、甾醇(菜油甾醇、谷甾醇)对陆源有机碳的输入及陆源有机碳的通量。生物标志物记录将与微体古生物(硅藻、甲藻等)有关。和矿物学(石英、长石等)在BIPOMAC的其他子项目中获得的沉积物芯以及格陵兰和南极冰芯的灰尘/Fe和CO2记录的古环境代理。连同其他BIPOMAC子项目,这项研究的结果将显着增加我们的知识(次)极地南太平洋和北太平洋气候变率,纬向和半球间遥相关,以及高纬度在驱动和放大全球气候变率的作用。在2009年7月/8月进行的索内“INOPEX”考察期间(该项目的一个重要里程碑),回收了独特的核心材料,这或多或少保证了计划研究的成功。
