Title: Collaborative Research: Establishing a High-resolution Temporal Record of Quaternary Climate-Glacial-Ocean Linkages in Southern Alaska (an IODP Site Survey)PI/Institution: John Jaeger, Florida; Ross Powell, Northern Illinois University; Joseph Stoner, University of Colorado at Boulder; Sean Gulick, University of Texas Institute of Geophysics; Ellen Cowan, Appalachian State University; Bruce Finney, University of Alaska-FairbanksAbstract:As part of a site survey for a proposed IODP program to drill marine sediments associated with late Cenozoic climate change and tectonic activity along the southern Alaskan margin, the researchers will combine efforts with an already funded piston coring and shallow imaging cruise and will acquire additional piston cores and high-resolution seismic images at proposed Gulf of Alaska drill sites. This region is believed to be analogous to, but have a smaller influence than, the Tibetan plateau in terms of the possible feedback between climate change and tectonics. The coring program has been designed to provide temporal resolution at sub-decadal to millennial time scales and sufficient spatial resolution to capture some of the variability in the provenance of marine sediments derived from glaciated source areas. The researchers will use the recovered core material to constrain the timing of deposition, sediment mixing rates, sediment fluxes, and sediment sources, to infer glacial dynamics, and to characterize basic visual and physical properties. In collaboration with Oregon State University colleagues, they will obtain additional information about paleotemperature, salinity, and oxygen conditions. The researchers will also process the marine seismic data for use in sequence stratigraphic correlations and baseline characterization of the proposed IODP drill sites.

标题：协作研究：建立在阿拉斯加南部的第四纪气候 - 冰川 - 海洋连接的高分辨率时间记录（IODP现场调查）PI/机构：佛罗里达州的John Jaeger； 北伊利诺伊大学罗斯·鲍威尔（Ross Powell）；科罗拉多大学博尔德分校的约瑟夫·斯托纳；肖恩·古利克（Sean Gulick），德克萨斯大学地球物理学院；阿巴拉契亚州立大学艾伦·考恩（Ellen Cowan）；布鲁斯·芬尼（Bruce Finney），阿拉斯加大学 - 费尔班克萨特大学（University of Alaska-Fairbanksabtrattract）：作为拟议的IODP计划的一部分钻机。 就气候变化与构造之间的反馈而言，该地区与藏族高原相比类似，但影响比藏族高原更小。 加油计划旨在在千禧一代为千禧一代时尺度和足够的空间分辨率提供时间分辨率，以捕获来自冰川源区域的海洋沉积物的某些可变性。 研究人员将使用回收的核心材料来限制沉积的时机，沉积物混合速率，沉积物通量和沉积物来源，推断冰川动力学，并表征基本的视觉和物理特性。 与俄勒冈州立大学同事合作，他们将获得有关古温度，盐度和氧气状况的其他信息。 研究人员还将处理用于序列地层相关性和拟议IODP钻头的基线表征的海洋地震数据。
