Marine Sediment Sampling Facility (MARSSAM) Oceanographic Instrumentation: Acquisition of a Vibracorer

位于俄勒冈州立大学的海洋沉积物采样组(MARSSAM)申请资金购买振芯系统。MARSSAM为大学国家海洋实验室系统(UNLS)社区提供全方位的取心服务，从表面采样到长度最长为~25米的活塞取心。MARSSAM在国家科学基金会(NSF)和其他联邦机构的支持下，与主要调查人员(PI)协调研究巡航时间，确定实现科学目标所需的设备，并确保设备与舰船能力兼容。作为这项任务的核心，MARSSAM根据科学私人投资机构的要求，将取心技术应用于学术研究舰队(ARF)的船只，以便他们能够回收研究所需的沉积物。MARSSAM设计、维护和重建取心设备，监督海上取心和元数据收集，并培训科学人员收集船上物理特性数据和岩心分裂。MARSSAM的技术人员还提供所需的后勤支持，以使取心设备往返于全球分布的研究船，以及在巡航后将岩心归还给NSF海洋地质档案。它为科学家提供基础设施支持，以使用该船及其共享仪器，以支持他们由NSF资助的海洋研究项目(这些项目单独接受NSF相关研究计划的单独审查)。共享仪器的获取、维护和操作允许美国国家科学基金会资助的任何美国大学或实验室的研究人员获得用于其研究的工作、校准的仪器，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NSF的法定使命，并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，被认为值得支持。

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.
