2016 Oceanographic Instrumentation

请求为马库斯·朗塞斯号R/V， 235？具有一般海洋学能力的全球地震船。这艘船归美国国家科学基金会所有，由哥伦比亚大学的拉蒙特-多尔蒂地球观测站根据合作协议运营。“朗塞斯”号与学术舰队的其他船只不同，它是指定的国家设施。它提供了对海洋、海底和海底固体土壤成像的独特组合能力。它是世界上唯一一艘能够进行3D地震调查和扩展偏移量2D调查的学术研究船。调谐的线性源阵列，由多达36个气枪组成，总容量为6,600立方英寸，也是该船的独特资产。2015年，R/V Langseth完成了194天，其中130天（67%）是由NSF资助的。2016年，时间表显示165天，全部用于NSF。该提案中要求的海洋仪器包括：Kongsberg Seapath 330 $44,320枪带缆和公用绞车无线控制器$96,959两个SEAL拖缆通信单元$56,160 $197,439更广泛的影响本提案的主要影响是根据提案指南（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。

A request is made to fund additional and back-up equipment on the R/V Marcus Langseth, a 235? Global seismic vessel with general oceanographic capabilities. The vessel is owned by NSF and operated by Lamont-Doherty Earth Observatory of Columbia University under a cooperative agreement. The Langseth is different than other vessels in the Academic Fleet in that it is a designated National Facility. It provides a unique combination of capabilities for imaging the oceans, the seafloor and the solid earth beneath the sea. It is the only vessel in the word dedicated to academic research that is capable of conducting 3D seismic surveys as well as extended offset 2D surveys. The tuned, linear source array, consisting of up to 36 air-guns, with a total capacity of 6,600 cu in is also unique asset of this vessel. In 2015, R/V Langseth completed 194 days, 130 (67%) of which were NSF funded. In 2016, the schedule shows 165 days, all of which are for NSF. Oceanographic Instrumentation requested in this proposal includes:Kongsberg Seapath 330 $44,320 Gun Umbilical and Utility Winches Wireless Controls $96,959 Two SEAL Streamer Communication Units $56,160 $197,439 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.
