R/V Marcus G Langseth - Oceanographic Instrumentation 2020

本提案中的仪器要求是更换Langseth上的震源控制器系统和相关设备。该设备已超出使用期限，供应商不再提供支持。该系统对船舶上的海洋地震采集至关重要。新系统是制造商支持的常用工业源控制器。所有仪器供所有国家科学基金会资助的研究人员共享使用gunlink 2K源控制器$988,264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。

The instrumentation request in this proposal is to replace the seismic source controller system and associated equipment on Langseth. The equipment is beyond end of life and no longer supported by the vendor. This system is critical to marine seismic acquisition on the vessel. The new system is a commonly used industry source controller that is manufacturer supported. All instrumentation is for shared use among all National Science Foundation funded researchersGunLink 2K Source Controller $988,264 Broader 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.
