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.

请求为 R/V Marcus Langseth（235？）上的额外和备用仪器提供资金。具有一般海洋学能力的全球地震船。该船由美国国家科学基金会 (NSF) 所有，并根据合作协议由哥伦比亚大学拉蒙特-多尔蒂地球观测站 (Lamont-Doherty Earth Observatory) 运营。 Langseth 与学术舰队中的其他船只不同，因为它是指定的国家设施。它提供了对海洋、海底和海底固体成像的独特功能组合。它是世界上唯一一艘致力于学术研究、能够进行 3D 地震勘测以及扩展偏移 2D 勘测的船只。调谐线性源阵列由多达 36 个气枪组成，总容量为 6,600 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，时间表显示 228 天，其中 73%（167 天）由 NSF 资助。本提案中要求的海洋仪器包括：Posnet 升级和工作站更换 $10,635 Sprint/Reflex 和 MOSAIC 工作站 $8,726 维萨拉气象站 $10,591 $29,952 更广泛的影响本提案的主要影响符合提案指南 (NSF 13-589) 的优点审查标准 2 。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。
