A proposal is made to fund instrumentation on the R/V Marcus Langseth, a 235’ Global seismic vessel with general oceanographic capabilities. The vessel is owned by Columbia University and operated by Lamont-Doherty Earth Observatory of Columbia University under a cooperative agreement with NSF. The Langseth is unique in the Academic Fleet in that 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 world 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 airguns, with a total capacity of 6,600 cu in is also unique asset of this vessel. All of the requested equipment in this proposal is for upgrading existing systems. Instrumentation requested in this proposal includes:4x Sercel Seal Short Head Section $75,2002x Sercel Seal Short Head Elastic Section Adapter $27,6921x Umbilical Armored lead-in $81,950 $184,842Broader Impacts The 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.

建议为R/V Marcus Langseth上的仪器提供资金，这是一艘具有一般海洋学能力的235'全球地震船。该船为哥伦比亚大学所有，由哥伦比亚大学的拉蒙特-多尔蒂地球观测站根据与国家科学基金会的合作协议运营。Langseth在学术舰队中是独一无二的，因为它提供了对海洋，海底和海底固体地球成像的独特组合能力。它是世界上唯一一艘专门用于学术研究的船只，能够进行3D地震调查以及扩展的偏移2D调查。调谐的线性震源阵列由多达36支气枪组成，总容量为6，600立方英寸，也是该船的独特资产。本提案中要求的所有设备都是用于升级现有系统。本建议书中要求的仪器包括：4x Sercel Seal短头部分$75，2002 x Sercel Seal短头弹性部分适配器$27，6921 x Umbridge装甲引入$81，950 $184，842更广泛的影响 本提案的主要影响是提案指南（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。
