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、Mountain 这项合作奖授予伍兹霍尔海洋研究所、俄勒冈州立大学和罗格斯大学，为测试新的活塞取芯系统提供支持，该系统是在 NSF 海洋科学部的支持下开发的，并且即将完成。 这种新的取芯系统旨在回收长达 42 米的大直径、扰动最小的活塞芯，为参与古气候、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提升。 它将安装在大型 UNOLS 船 R/V Knorr 上，该船已为此目的进行了加固，取芯系统包括带有合成缆绳的新型高性能绞车系统、新型 A 形框架和专门的取芯处理系统，以优化安全部署和恢复。 测试将在百慕大隆起和新泽西边缘的先前充分研究的区域进行，以便可以在新的取芯器和现有系统之间进行详细的比较。 部署测试将改变核心长度和重量，以及筒壁直径的不同组合。 他们将解决自由落体长度和拉力问题，仔细研究反弹作为水深和核心重量的函数。 测试还将解决两个研究区域不同水深和沉积物类型的差异。 船上测试将包括使用多传感器轨道系统测量密度、磁化率、纵波速度以及沉积物颜色的详细分析。***
