该提案要求447 279美元，用于为联合国海洋法办事处船队的海洋级船只建造一个便携式巨型活塞取芯系统。沉积物取芯支持地球科学各种学科的高影响力科学。获得可靠的取芯系统对于解决一些具有科学和社会重要性的关键问题至关重要，包括海洋科学十年调查中概述的几乎所有科学优先事项。尽管沉积物取芯技术仍然很重要，但社区普遍担心美国研究界的沉积物取芯能力受到侵蚀。根据2015年5月在美国国家科学基金会召开的一次研讨会上对社区调查和讨论的回应，科学界表示高度重视开发一种强大的便携式巨型活塞取心系统，该系统能够部署在所有全球级和海洋级船舶上，并能够在整个海洋深度范围内收集长达20米的岩心。2015- 2025年海洋沉积物取芯需求的科学驱动评估，？NSF研讨会报告，2015年5月28日至29日）。更广泛的影响本提案的主要影响是提案指南（NSF 13-589）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任何美国大学或实验室的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。

This proposal requests $447,279 to build a portable Jumbo Piston Coring System for the Ocean Class vessels of the UNOLS Fleet.Sediment coring supports high impact science in a diverse array of disciplines in the geosciences.Access to reliable coring systems is essential for addressing a number of critical questions of both scientific and societal importance, including almost all of the scientific priorities outlined in the Decadal Survey of Ocean Sciences. Despite the continued importance of sediment coring technologies, there is widespread community concern that there has been an erosion of sediment coring capability available to the U.S. research community. Based on the responses to a community survey and discussions during a workshop convened at the National Science Foundation in May 2015, the scientific community expressed a high priority for the development of a robust and portable Jumbo Piston Coring system that is capable of deployment on all Global and Ocean Class vessels and capable of collecting cores of up to 20 m length over the full range of ocean depths (?Science Driven Assessment of Needs for marine Sediment Coring 2015- 2025,? Report of Workshop at NSF, 28-29 May 2015).Broader ImpactsThe principal impact of the present proposal is under Merit Review Criterion 2 of the Proposal Guidelines (NSF 13-589). 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
