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.***

0342067 Diebold授予位于纽约市的哥伦比亚大学的Lamont-Doherty地球观测站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拖缆，以显著提高研究船Maurice Ewing的地球物理调查能力，Maurice Ewing是NSF拥有的船舶，由LDEO作为大学-国家海洋学实验室系统研究船队的一部分运营。 增强的系统可以容纳在现有的R/V尤因处理系统，因此立即投入使用，提供长，深穿透数据采集与增加的长度（从目前的6公里最大值）以及在浅层研究的高分辨率数据采集方面的实质性改进，因为拖缆包括1.5km的6.25米组间距段以及6.5km的12.5米段加上备件。 该系统将提供三维多拖缆能力，目前正在考虑将其作为R/V Ewing改装或购买替换船的一部分，这里支持的地震系统将在任何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生物学家带来巨大优势，我们预计该系统将大量用于支持NSF正在进行的主要研究计划，包括综合大洋钻探计划（IODP），EarthScope，MARGINS和RIDGE 2000。
