R/V Marcus G. Langseth- Shakedown and Science Testing

0551926 Diebold该奖项授予纽约市的哥伦比亚大学，为R/V Marcus G Langseth上的科学仪器和系统的测试提供支持，该研究船于2007年投入运营，是大学国家海洋学实验室系统的一部分。 R/V Langseth号目前正在从其先前的使命转换为8拖缆多道地震（MCS）测量船（M/V Western Legend）改为更适合执行更广泛的海洋地球物理研究使命的船舶，包括4拖缆MCS、使用多达100个海底地震仪的折射、重力、磁力、多波束海底测绘、海底取样、拖曳声纳，以及部署其他海洋学仪器。 测试将于2006年冬季在墨西哥湾开始，将包括所有新的跨甲板科学系统的运行，重点是导航系统、船外装卸设备、多波束海底测绘系统，特别是地震仪器，包括多震源阵列和使用扫雷器的多拖缆。 测试还将包括记录地震数据以评估质量，并计划进行为期5至6天的三维地震调查，以全面评估船舶和拖缆导航能力、软件性能和整体地震调查质量。 该数据集将提供给希望评估系统能力和性能的研究人员，并将作为那些为未来地震研究项目准备研究建议的初步指南。

0551926DieboldThis award to Columbia University in the City of New York provides support to test scientific instrumentation and systems on R/V Marcus G Langseth, a research vessel entering operation in 2007 as part of the University-National Oceanographic Laboratory System. R/V Langseth is presently undergoing conversion from its previous mission as an 8-streamer multi-channel seismic (MCS) survey vessel (M/V Western Legend) to a vessel more appropriate for conducting a broader mission of marine geophysical research including 4-streamer MCS, refraction using up to 100 ocean bottom seismometers, gravity, magnetics, multi-beam seafloor mapping, seafloor sampling, towed sonars, and deployment of other oceanographic instruments. Testing will begin in winter 2006 in the Gulf of Mexico, and will include operation of all new and cross-decked science systems, emphasizing navigation systems, over-side handling equipment, the multi-beam seafloor mapping system and, particularly, the seismic instrumentation, including multiple source arrays and multiple streamers using paravanes. Testing will also include recording seismic data to evaluate quality, and plans call for conducting a 5- to 6-day 3-D seismic survey to fully evaluate vessel and streamer navigation capabilities, software performance and overall seismic survey quality. This data set will be available for researchers who desire to evaluate system capabilities and performance, and will serve as an initial guide for those preparing research proposals for future seismic research projects.
