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

项目概述本建议书中要求的仪器将用于增强朗塞特？S的R/V地震功能和可靠性。该提案指出，用拟议的Sercel SEAL 408系统取代现有的SYNTRAK MCS系统，对于朗塞特公司和需要它进行地震成像的科学界的未来至关重要。参考的是朗塞斯？克利恩村？在2010年的科学讲习班报告中，科学优先事项提供了关于需要更有能力的系统的未来科学目标的详细信息。目前的系统已有20多年的历史，不再受支持，远远超过其预期使用寿命。为了满足科学界的需求，升级国家地震成像设施的多道地震(MCS)能力是必要的。提案的前提是购买Sercel Seal 408满足这些要求，并以财政负责的方式做到这一点。广泛影响本报告的主要影响是根据提案指南(NSF 13-589)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、维护和操作使任何美国大学或实验室的NSF资助的研究人员都可以获得用于其研究的工作、校准的仪器，从而降低了研究成本，并扩大了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.
