0631574, Curry0631854, Pisias0632006, MountainThis collaborative award to Woods Hole Oceanographic Institution, Oregon State University and Rutgers University provides support to test a new piston coring system that has been developed with support from the NSF Division of Ocean Sciences, and is nearing completion. This new coring system has been designed to recover large diameter, minimally disturbed piston cores up to 42 meters long, offering a major increase in capability to U.S. marine geoscientists involved in paleoclimate, paleoceanography or continental margin research, in particular. It will be installed on R/V Knorr, a large UNOLS vessel, which has been strengthened for this purpose, and the coring system includes a new, high performance winch system with synthetic cable, a new A-frame and specialized core handling system to optimize safe deployment and recovery. The tests will be carried out on the Bermuda Rise and New Jersey margin in areas well studied previously so that detailed comparisons can be carried out between the new corer and existing systems. Deployment tests will vary core length and weight, as well as different combinations of barrel wall diameters. They will address freefall length and pullout, looking carefully at rebound as a function of water depth and core weight. Testing will also address differences related to the different water depths and sediment types in the two study areas. Shipboard tests will include detailed analysis using a multi-sensor track system to measure density, magnetic susceptibility and P-wave velocity as well as sediment color.***

0631574，Curry0631854，Pisias0632006这个授予伍兹霍尔海洋研究所、俄勒冈州立大学和罗格斯大学的合作奖项为测试新的活塞取心系统提供了支持，该系统得到了美国国家科学基金会海洋科学部的支持，已接近完成。这一新的取心系统旨在回收长达42米的大直径、干扰最小的活塞岩芯，特别是为从事古气候、古海洋学或大陆边缘研究的美国海洋地球科学家提供了极大的能力。它将安装在联合国难民事务高级专员公署为此目的而加固的大型船只R/V Knorr上，取芯系统包括一个新的高性能绞车系统和一个新的A型框架和专门的核心处理系统，以优化安全部署和回收。测试将在百慕大隆起和新泽西边缘地区进行，这些地区之前进行了充分的研究，以便可以在新的取样器和现有系统之间进行详细的比较。部署测试将改变岩心长度和重量，以及不同的筒壁直径组合。他们将讨论自由落体的长度和拉出，仔细研究反弹作为水深和岩心重量的函数。测试还将解决与两个研究区不同水深和沉积物类型有关的差异。船上的测试将包括使用多传感器跟踪系统进行详细分析，以测量密度、磁化率、P波速度以及沉积物颜色。
