Acquisition of a Multi-Sensor Core Logger for Syracuse University

这笔国家科学基金会(NSF)拨款支持为锡拉丘兹大学地球科学系购买多传感器岩心记录仪(MSCL)。MSCL扫描钻探的沉积物和岩石岩芯，并确定它们的性质。MSCL使用几个传感器来检测颜色变化、沉积物密度、磁性和声速。描述不同环境中的地球物质是古气候和古环境研究的基础。这样的研究有助于我们对气候变化和地球系统过程的理解。此外，MSCL还为识别地下污染物提供了有价值的信息，并为工程、地质考古和地质资源评估提供了信息。该仪器支持美国国家科学基金会促进科学进步、促进国民健康、繁荣和福利的使命。这项技术将提供给纽约州北部其他机构的学生和教职员工，并将使来自区域地球科学和环境科学界的不同研究人员受益。此外，复杂的传感器阵列在单个仪器中结合了几种地球科学技术，使MSCL成为STEM教育推广和培训的宝贵工具。由国家科学基金会向锡拉丘兹大学提供的这笔资金资助的多传感器岩心记录仪包括以下部件：1)带有计算机和软件的MSCL-S基础系统，2)用于测量声波传播的声波系统，3)伽马密度测量系统，4)整个和分割岩芯的磁化率系统，5)用于量化颜色和岩性的彩色光谱系统(波长360-740 nm)，6)用于拍摄高分辨率岩心照片的行扫描相机。集成的MSCL-S系统将用于锡拉丘兹大学地球科学系的几名教员的研究，这些教员在使用核心材料重建古环境方面具有专业知识。该系的教员研究将得到该仪器的支持，包括利用湖泊-沉积物中的颜色光谱和岩性变化来研究新生代期间的热带干旱和海洋-大气联系，以及晚第四纪期间的北极气候和永久冻土动力学。在一系列地质时间尺度上研究盆地演化的研究人员将使用MSCL-S上的伽马和纵波传感器组合来创建合成地震图，从而能够根据盆地范围的地震反射数据精确校准岩心材料。使用缺氧湖沉积物和地质样本来探索全球碳循环和海洋缺氧事件的正在进行的部门研究也将受益于使用该仪器上的传感器套件。此外，纽约州北部的教育推广、基于当地的研究项目以及资源开发和管理将直接受益于该仪器在锡拉丘兹大学的中心位置。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

This National Science Foundation (NSF) grant supports the purchase of a multi-sensor core logger (MSCL) for the Department of Earth Sciences, Syracuse University. The MSCL scans drilled sediment and rock cores and identifies their properties. The MSCL uses several sensors to detect color variations, sediment density, magnetic properties, and sound speed. Describing earth materials from different environments is fundamental to paleoclimate and paleoenvironmental research. Such research informs our understanding of climate change and earth system processes. In addition, the MSCL provides valuable information for identifying subsurface pollutants, and provides information for engineering, geoarcheology, and geological resource assessment. This instrument supports the NSF mission of promoting the progress of science and advancing the national health, prosperity and welfare. This technology will be available to students and faculty from other institutions in Upstate New York and will benefit diverse researchers from regional geoscience and environmental science communities. Moreover, the sophisticated array of sensors combines several earth science techniques in a single instrument making the MSCL a valuable tool for STEM educational outreach and training.The multi-sensor core logger (MSCL) funded by this grant to Syracuse University from the National Science Foundation includes the following components: 1) the MSCL-S base system with computer and software, 2) an acoustic P-wave system for measuring sound-wave propagation, 3) a gamma-density measurement system, 4) a magnetic susceptibility system for whole and split cores, 5) a color-spectroscopy system (wavelengths 360-740 nm) for quantifying color and lithology, and 6) a line-scan camera for high-resolution core photos. The integrated MSCL-S system will be used in the research of several faculty members in the Department of Earth Science at Syracuse University with expertise in paleoenvironmental reconstructions using core materials. Faculty research in the department that will be supported by this instrument include using color spectroscopy and lithological changes in lake-sediments to investigate tropical drought and ocean-atmosphere linkages during the Cenozoic, as well as Arctic climate and permafrost dynamics over the late Quaternary. Researchers studying basin evolution over a range of geologic timescales will use the combination of gamma and p-wave sensors on the MSCL-S to create ?synthetic seismograms?, which allow for precise calibration of core material to basin-wide seismic reflection data. Ongoing departmental research using a combination of anoxic lake sediments and geologic samples to explore global carbon cycle and ocean anoxic events will also benefit from access to the suite of sensors on this instrument. Furthermore, educational outreach, locally-based research projects, and resource development and management in Upstate New York will directly benefit from the central location of the instrument at Syracuse University.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
