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

哥伦比亚大学的Lamont-Doherty地球天文台(LDEO)建议支持R/V Marcus Langseth上的技术服务，作为大学-国家海洋实验室系统(UNLS)计划的美国学术舰队的一部分。兰塞特房车，235？2005年从西部GECO购买的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能力)由美国国家科学基金会拥有，并取代了236？LDEO在1990至2005年间运营了一艘科考船。LDEO正在申请资金，以支持多道地震数据采集的基本和专门服务。他们提议为每个远洋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，并为合格用户提供支助。专业服务包括单缆和多缆地震作业。LDEO建议单缆模式配备8名技术人员，多缆模式配备12名技术人员。这项提案中的预算是为期5年的持续拨款的第一年。广泛影响本提案的主要影响是在标准2下，为科学家使用该船及其共享仪器提供基础设施支持，以支持他们由NSF资助的海洋研究项目(这些项目分别由NSF的相关研究计划单独审查)。对共用仪器的维护和操作的支持使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都可以为他们的研究使用经过校准的工作仪器，从而降低了研究成本，并扩大了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.
