R/V Langseth - Oceanographic Instrumentation 2015 II (Streamer)

项目概述：本提案中要求的仪器将用于增强朗塞斯？S抗震功能和可靠性。该提案指出，用拟议的Sercel SEAL 408系统取代现有的SYNTRAK MCS系统对Langseth公司和科学界的未来至关重要，因为地震成像需要该系统。提到了朗塞斯夫妇？斜坡村吗?在2010年的科学研讨会报告中，科学优先事项提供了未来科学目标的细节，这些目标需要一个更有能力的系统。目前的系统已经使用了20多年，不再得到支持，远远超出了预期的使用寿命。为了满足科学研究的需要，提高国家地震成像设备的多通道地震成像能力是必要的。该提案的前提是，购买Sercel SEAL 408满足这些要求，并以财政上负责任的方式这样做。更广泛的影响本报告的主要影响是根据建议指南（NSF 13-589）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。

Project SummaryThe instrumentation requested in this proposal will be used to enhance R/V Langseth?s seismic functionality and reliability. The proposal states that replacing the existing SYNTRAK MCS system with the proposed Sercel SEAL 408 system is critical for the future of Langseth and the science community that requires it for seismic imaging. References are made to the Langseth ?Incline Village? Science workshop report in 2010, where the science priorities provided detail on future scientific goals that require a more capable system. The current system is more than 20 years old, is no longer supported and is well beyond its expected service life. In order to meet the needs of scientific community, upgrading the multi-channel seismic (MCS) capabilities of the National Seismic Imaging Facility is a necessity. The premise of the proposal is that the purchase of the Sercel SEAL 408 satisfies these requirements and does so in a fiscally responsible way.Broader ImpactsThe principal impact of the present report 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.
