2016 Oceanographic Instrumentation

请求为R/V Marcus Langseth（235？具有一般海洋学能力的全球地震船。该船由NSF拥有，由哥伦比亚大学的Lamont-Doherty地球观测站根据合作协议运营。朗塞斯号与学术舰队中的其他船只不同，因为它是指定的国家设施。它提供了一个独特的能力组合，用于对海洋、海底和海底固体地球进行成像。它是世界上唯一一艘致力于学术研究的船只，能够进行3D地震勘探以及扩展的偏移2D勘探。调谐的线性震源阵列由多达36支气枪组成，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%）由NSF资助。在2016年，时间表显示165天，所有这些都是为NSF。本提案中要求的海洋学仪器包括：孔斯贝格Seapath 330型44 320美元炮管和公用绞车无线控制器96 959美元两个SEAL拖缆通信装置56 160美元 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、维护和操作使任何美国大学或实验室的NSF资助的研究人员都可以使用经过校准的工作仪器进行研究，从而降低研究成本，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.
