Oceanographic Technical Services, R/V Marcus G. Langseth, 2012 ? 2016

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购买的一艘地震勘测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。 它们提议为每个海上研究项目提供至少三名技术员，以提供基本服务和维护设备、校准传感器并为合格用户提供支助。 专业服务包括单电缆和多电缆地震作业。LDEO建议为单电缆模式配备8名技术人员，为多电缆模式配备12名技术人员。更广泛的影响本提案的主要影响是在标准二下，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，以支持他们的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）。 对共享使用仪器的维护和操作的支持允许来自任何美国大学或实验室的NSF资助的研究人员访问工作，校准仪器进行研究，降低研究成本，并扩大潜在研究人员的基础。

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 single cable and multiple cable seismic operations. LDEO proposes to sail eight technicians for single cable mode and 12 technicians for multi-cable mode. The budget in this proposal is for the first year of a 5-year continuing grant.Broader ImpactsThe principal impact of the present proposal is under criterion two, providing 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 support of 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.
