R/V Marcus G. Langseth - Oceanographic Instrumentation 2015

提出了一项申请，以资助R/V Marcus Langseth上的额外和后备仪器，一台235？具有一般海洋能力的全球地震船。这艘船由美国国家科学基金会所有，由哥伦比亚大学拉蒙特-多尔蒂地球天文台根据合作协议运营。朗塞斯号不同于学术舰队中的其他船只，因为它是指定的国家设施。它提供了对海洋、海底和海底固体地球成像的独特组合。它是世界上唯一一艘致力于学术研究的船只，能够进行三维地震测量以及扩展偏移距二维测量。调谐的线性震源阵列，由多达36支气枪组成，总容量为6600立方英寸，也是该船的独特资产。2014年，R/V Langseth完成了139天，其中114天(82%)由NSF资助。2015年，日程表显示228天，其中73%(167天)由NSF资助。本建议书要求的海洋仪器包括：POSnet升级和工作站更换$10,635 Sprint/Reflex和马赛克工作站$8,726 Vaisala气象站$10,591$29,952布罗德影响本建议书的主要影响是根据建议书指南(NSF 13-589)的功绩审查标准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、维护和操作使任何美国大学或实验室的NSF资助的研究人员都可以获得用于其研究的工作、校准的仪器，从而降低了研究成本，并扩大了潜在研究人员的基础。

A request is made to fund additional and back-up instrumentation on the R/V Marcus Langseth, a 235? Global seismic vessel with general oceanographic capabilities. The vessel is owned by NSF and operated by Lamont-Doherty Earth Observatory of Columbia University under a cooperative agreement. The Langseth is different than other vessels in the Academic Fleet in that it is a designated National Facility. It provides a unique combination of capabilities for imaging the oceans, the seafloor and the solid earth beneath the sea. It is the only vessel in the word dedicated to academic research that is capable of conducting 3D seismic surveys as well as extended offset 2D surveys. The tuned, linear source array, consisting of up to 36 air-guns, with a total capacity of 6,600 cu in is also unique asset of this vessel. In 2014, R/V Langseth completed 139 days, 114 (82%) of which were NSF funded. In 2015, the schedule shows 228 days, 73% (167 days) of which are NSF funded. Oceanographic Instrumentation requested in this proposal includes:Posnet Upgrade and workstation replacement $10,635Sprint/Reflex and MOSAIC workstations $8,726Vaisala Weather Station $10,591 $29,952Broader 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.
