R/V Marcus G Langseth - Oceanographic Instrumentation 2020

本提案中的仪器要求是更换朗塞斯的震源控制器系统和相关设备。设备已超过使用寿命，不再受供应商支持。该系统对舰船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。所有仪器供国家科学基金会资助的所有研究人员共享使用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、维护和操作允许美国国家科学基金会资助的任何美国大学或实验室的研究人员获得用于其研究的工作、校准的仪器，从而降低研究成本，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智力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.
