Trustees of Columbia University in the City of New York/Langseth Oceanographic Instrumentation

一项建议是为R/V Marcus Langseth提供仪器设备，这是一艘235英尺的全球地震船，具有一般的海洋学能力。这艘船归哥伦比亚大学所有，由哥伦比亚大学的Lamont-Doherty地球观测站根据与美国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、海底和海底固体土壤成像的综合能力。它是世界上唯一一艘专门用于学术研究的船，可以进行3D地震调查以及扩展偏移量的2D调查。调谐的线性源阵列，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。本建议所要求的所有设备都是为了升级现有系统。该提案中要求的仪器包括：Seamap浮标链接4DX GNSS源跟踪系统$224,016Cisco Meraki计算机网络全船升级$36,135Seamap近场水听器和HVRU $43,215 $303,366更广泛的影响本提案的主要影响是根据提案指南（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国家科学基金会资助的海洋学研究项目（这些项目单独接受国家科学基金会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资助的研究人员为他们的研究访问工作、校准仪器，降低研究成本，并扩大潜在研究人员的基础。该奖项反映了美国国家科学基金会的法定使命，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。

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 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 can conduct 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:Seamap BuoyLink 4DX GNSS Source Tracking system $224,016Cisco Meraki computer Network vessel-wide upgrade $36,135Seamap Near Field Hydrophones and HVRU $43,215 $303,366Broader 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.
