This proposal seeks funds for acquisition of a seagoing computed tomography (CT)-scanning system for the Oregon State University Marine Sediment Sampling Facility (MARSSAM), which supports NSF coring programs across the United State Academic Research Fleet (ARF). The system they propose to acquire, a GeoTek Vertical X-ray CT-scanner (VXCT) has a small footprint allowing it to be installed in a containerized lab for deployment aboard many of the ARF platforms. The scanner can collect three-dimensional images at resolutions of between 350 and 30 microns for cores of up to 150 cm in length in a vertical orientation, allowing for preservation of the sediment water interface. Full-length core sections can be scanned in as little as 40 minutes at 64-micron resolution, allowing for data collection at a pace that falls within the flow of core processing aboard the shipSeagoing Sediment Core Computed Tomography Scanner $611,799 Broader ImpactsThe principal impact of the present proposal is under Merit Review Criterion 2 of the Proposal Guidelines (NSF 19-602). It provides infrastructure support for scientists to use the vessel and its shared-use instrumentation in support of their NSF-funded oceanographic research projects (which individually undergo separate review by the relevant research program of NSF). The acquisition, maintenance and operation of shared-use instrumentation allows NSF-funded researchers from any US university or lab access to working, calibrated instruments for their research, reducing the cost of that research, and expanding the base of potential researchers.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.

该提案为俄勒冈州立大学海洋沉积物采样设施（MARSSAM）的海洋计算机断层扫描（CT）扫描系统寻求资金，该系统支持美国学术研究机队（ARF）的NSF Coring计划。他们建议获取的系统，Geotek垂直X射线CT-SCANNER（VXCT）的占地面积很小，允许将其安装在许多ARF平台上的容器化实验室中进行部署。扫描仪可以在350至30微米之间的分辨率上收集三维图像，以在垂直方向上长达150厘米的核心，从而保留沉积物水界面。 Full-length core sections can be scanned in as little as 40 minutes at 64-micron resolution, allowing for data collection at a pace that falls within the flow of core processing aboard the shipSeagoing Sediment Core Computed Tomography Scanner $611,799 Broader ImpactsThe principal impact of the present proposal is under Merit Review Criterion 2 of the Proposal Guidelines (NSF 19-602).它为科学家提供了基础设施支持，以使用该船及其共享用途的仪器来支持其NSF资助的海洋学研究项目（NSF相关研究计划单独进行了审查）。 共享使用工具的获取，维护和操作允许NSF资助的任何美国大学或实验室访问工作，校准其研究的仪器，降低该研究的成本，并扩大潜在研究人员的基础。本奖项奖反映了NSF的立法任务，并被认为是通过基金会的智力评估和广泛的评估来评估的，并值得通过评估来进行评估。
