Oceanographic Technical Services, LDEO, 2018-2022

哥伦比亚大学的拉蒙特-多尔蒂地球观测站（LDEO）建议支持R/V Marcus Langseth的技术服务，作为大学-国家海洋学实验室系统（UNOLS）计划的美国学术船队的一部分。 R/V Langseth，一个235？2005年从Western GECO购买的一艘地震调查船将作为地球物理研究船（具有一些额外的通用海洋学能力）运营，由国家科学基金会拥有，并取代了R/V Maurice Ewing，一艘236？1990年至2005年由LDEO运营的研究船。LDEO正在申请资金，以支持多通道地震数据采集的基本和专业服务。 他们提议为每个海上研究项目提供至少三名技术人员，以提供基本服务和维护设备，校准传感器，并为合格的用户提供支持。 专业服务包括2018年的2D和3D多通道地震支持和哺乳动物减灾工作。LDEO建议8名技术人员进行2D地震工作，10-12名技术人员进行3D地震工作。本提案中的预算用于5年连续赠款的第一年。该奖项的第一年将与该计划进行谈判，并将估计出几年。由于船舶是每年计划，这是不可能的项目NSF？在我们这些年的总使用量中所占的比例。因此，第二年至第五年的预算将在收到详细说明这些时间表和相关费用的年度报告后进行谈判。 本提案的主要影响是提案指南（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NSF资助的海洋学研究项目（这些项目单独接受NSF相关研究计划的单独审查）。 共享使用仪器的获取、维护和操作允许来自美国任何大学或实验室的NSF资助的研究人员使用工作、校准的仪器进行研究，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。

Lamont-Doherty Earth Observatory (LDEO) of Columbia University proposes to support technical services on R/V Marcus Langseth as part of the U.S. Academic Fleet which is scheduled by the University-National Oceanographic Laboratory System (UNOLS). R/V Langseth, a 235? seismic survey vessel purchased in 2005 from Western GECO to be operated as a geophysical research vessel (with some additional general purpose oceanographic capabilities) is owned by the National Science Foundation and replaced R/V Maurice Ewing, a 236? research vessel operated by LDEO from 1990 to 2005.LDEO is requesting funds to support both basic and specialized services for multichannel seismic data acquisition. They propose to provide at least three technicians on each seagoing research project to provide basic services and to maintain equipment, calibrate sensors, and provide support for qualified users. Specialized services include both 2D and 3D Multichannel seismic support and Mammal Mitigation efforts for 2018. LDEO proposes to sail eight technicians for the 2D seismic work and 10-12 techs for 3D. The budget in this proposal is for the first year of a 5-year continuing grant. The first year of this award will be negotiated with the Program and out-years will be estimated. Because ships are scheduled annually, it is not possible to project NSF?s fraction of total usage in out years. Therefore, budgets for Years 2 through 5 will be negotiated after receipt of Annual Reports that detail those schedules and associated costs.Broader Impacts The principal impact of the present proposal 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.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.
