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.

位于俄勒冈州州立大学的海洋沉积物取样小组（MARSSAM）要求提供资金，用于购买一个振动芯系统。MARSSAM为大学国家海洋学实验室系统（UNOLS）社区提供全方位的取芯服务，从表面取样到长度达25米的活塞岩心。MARSSAM与主要研究者（PI）协调，研究巡航时间由国家科学基金会（NSF）和其他联邦机构支持，确定实现科学目标所需的设备，并确保设备与船舶能力兼容。作为这项任务的核心，MARSSAM根据科学PI的要求，将取芯技术应用于学术研究船队（ARF）的船只，以便他们能够恢复研究所需的沉积物。MARSSAM设计，维护和重建取芯设备，监督海上取芯和元数据收集，并培训科学部门收集船上物理特性数据和岩心分裂。 MARSSAM技术人员还提供所需的后勤支持，以便在全球分布的研究船之间来回循环取芯设备，并在巡航后将岩心送回NSF海洋地质档案馆。 更广泛的影响本提案的主要影响是根据提案指南（NSF 19-602）的优点审查标准2。它为科学家提供基础设施支持，以使用该船及其共享使用的仪器来支持他们的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）。 共享使用仪器的获取、维护和操作允许来自美国任何大学或实验室的NSF资助的研究人员使用工作、校准的仪器进行研究，降低研究成本，并扩大潜在研究人员的基础。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
