The Marine Sediments Sampling Group (MARSSAM) located at Oregon State University requests funds for the purchase of a vibracore system. MARSSAM provides the full gamut of coring services to the University National Oceanographic Laboratory System (UNOLS) community, from surface sampling to piston cores of up to ~25 m in length. MARSSAM coordinates with principal investigators (PIs) with research cruise time supported by the National Science Foundation (NSF) and other federal agencies, determining what equipment is necessary for the accomplishment of scientific goals, and ensuring that equipment is compatible with vessel capabilities. Central to this mandate, MARSSAM adapts coring technology to the vessels of the Academic Research Fleet (ARF) requested by science PIs so that they can recover the sediments needed for their research. MARSSAM designs, maintains, and rebuilds coring equipment, supervising coring and meta-data collection at sea, and training the science party in the collection of shipboard physical properties data and core splitting. MARSSAM technicians also provide logistical support needed to cycle coring gear to and from globally distributed research vessels as well as to return cores to NSF marine geology archives post cruise.Vibracoring System $126,222 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.

位于俄勒冈州立大学的海洋沉积物采样小组 (MARSSAM) 请求资金购买 vibracore 系统。 MARSSAM 为大学国家海洋实验室系统 (UNOLS) 社区提供全方位的取芯服务，从表面采样到长度长达约 25 m 的活塞取芯。 MARSSAM 在美国国家科学基金会 (NSF) 和其他联邦机构支持的研究巡航时间中与主要研究者 (PI) 进行协调，确定实现科学目标所需的设备，并确保设备与船舶功能兼容。作为这项任务的核心，MARSSAM 将取芯技术应用于科学 PI 要求的学术研究舰队 (ARF) 的船只，以便他们能够回收研究所需的沉积物。 MARSSAM 设计、维护和重建取芯设备，监督海上取芯和元数据收集，并培训科学团队收集船上物理特性数据和岩芯分裂。 MARSSAM 技术人员还提供在全球分布的研究船之间循环取芯设备所需的后勤支持，以及在巡航后将岩芯返回 NSF 海洋地质档案。振动取芯系统 126,222 美元更广泛的影响当前提案的主要影响是根据提案指南 (NSF 19-602)。它为科学家使用该船及其共享仪器提供基础设施支持，以支持其 NSF 资助的海洋学研究项目（这些项目单独接受 NSF 相关研究计划的单独审查）。 共享仪器的采购、维护和操作使美国任何大学或实验室的 NSF 资助的研究人员都可以使用经过校准的工作仪器进行研究，从而降低研究成本，并扩大潜在研究人员的基础。该奖项反映了通过使用基金会的智力价值和更广泛的影响审查标准进行评估，NSF 的法定使命被认为值得支持。
