Upgrade of Multichannel Seismic Capabilities on the Research Vessel MAURICE EWING

授予纽约市哥伦比亚大学Lamont-Doherty地球天文台的这一奖项提供了一种新的多通道地震反射采集系统，包括一个8公里长的固态水听器流缆，以显著提高莫里斯·尤因号科考船的地球物理调查能力，莫里斯·尤因号是美国国家科学基金会所有的船，由LDEO运营，作为大学-国家海洋实验室系统研究船队的一部分。增强型系统可以安装在现有的R/V尤文处理系统上，因此可以立即投入使用，提供增加了长度的长、深穿透数据采集(目前的最大长度为6公里)，并大幅改进了浅层研究的高分辨率数据采集，因为拖缆包括1.5公里的6.25米组间距区段以及6.5公里长的12.5米区段和备件。该系统将支持3-D、多条拖缆能力，目前正在考虑将其作为R/V尤文改装或购买替代船的一部分，这里支持的地震系统将在任何一种情况下为学术研究人员提供更好的能力。我们预计，这些改进将对使用该船进行研究的海洋地球物理学家有很大的好处，我们预计该系统将大量用于支持正在进行的主要NSF研究倡议，包括综合海洋钻探计划(IODP)、地球范围、边缘和海脊2000。*

0342067DieboldThis award to Lamont-Doherty Earth Observatory of Columbia University in the City of New York provides a new multichannel seismic reflection acquisition system, including an 8-kilometer solid state hydrophone streamer, to significantly improve the geophysical survey capabilities of the research vessel Maurice Ewing, an NSF-owned ship operated by LDEO as part of the University-National Oceanographic Laboratory System research fleet. The enhanced system can be accommodated on the existing R/V Ewing handling system, and thus put to immediate use, providing both long, deep-penetration data acquisition with the increased length (from the present 6 kilometer maximum) as well as substantial improvement in high resolution data acquisition for shallower studies, since the streamer includes 1.5 km of 6.25-meter group spacing sections as well as 6.5 kilometers of 12.5-meter sections plus spares. The system will accommodate 3-D, multiple streamer capabilities, which are presently being considered either as part of a refit of R/V Ewing or acquisition of a replacement vessel, and the seismic system supported here will provide improved capabilities for academic researchers under either scenario. We anticipate that these improvements will be of substantial advantage to marine geophysicists using the ship in their research, and we anticipate substantial use of the system to support major ongoing NSF research initiatives, including the Integrated Ocean Drilling Program (IODP), EarthScope, MARGINS and RIDGE 2000.***
