0421110GiosanThis Major Research Instrumentation award to Woods Hole Oceanographic Institution (WHOI) in Massachusetts provides funds for acquisition of a scanner that combines capabilities for rapid, non-desrtructive, ultra-high-resolution analyses of X-ray fluorescence (XRF) bulk geochemistry, digital X-radiography, and digital photography. The instrument will be applied principally to the study of core samples of marine sediments, providing a unique capability for U.S. researchers. The instrument provides rapid measurements of chemical elements between aluminum (atomic number 13) and uranium (atomic number 92), co-registered with high resolution images of the surface and subsurface structure of the sample. Research projects that are expected to take advantage of the project initially include studies of climate and climate change at a number of scales, as well as studies of ocean circulation, terrestrial weathering, sediment source identification, and anthropogenic impacts on coastal environments. The broader impact of the acquisition includes providing a facility with unique capabilities for US from around the U.S, as well as enabling a capability to study a wide array of projects with compelling societal relevance (climate change, pollution, erosion). WHOI is providing cost-share towards the equipment acquisition of 30% of the project cost from non-federal funds. This proposal is supported by the Division of Ocean Sciences at NSF. ***

美国马萨诸塞州伍兹霍尔海洋研究所（WHOI）获得的主要研究仪器奖为购买一种扫描仪提供了资金，该扫描仪结合了快速、非破坏性、超高分辨率的x射线荧光（XRF）块状地球化学分析、数字x射线照相和数字摄影的能力。该仪器将主要用于研究海洋沉积物的岩心样本，为美国研究人员提供独特的能力。该仪器提供了铝（原子序数13）和铀（原子序数92）之间的化学元素的快速测量，并与样品表面和地下结构的高分辨率图像共同注册。预计将利用该项目的研究项目最初包括在若干尺度上研究气候和气候变化，以及研究海洋环流、陆地风化、沉积物来源鉴定和人为对沿海环境的影响。此次收购的更广泛影响包括为美国提供一个具有独特功能的设施，并使其能够研究具有引人注目的社会相关性（气候变化，污染，侵蚀）的广泛项目。世卫组织将从非联邦基金中分摊30%的项目费用，用于设备购置。该提案得到了美国国家科学基金会海洋科学部的支持。＊＊＊
