Collaborative Research: An Abyssal Circulation Type Section for the North Atlantic

提供资金分析从北大西洋百慕大海隆回收的七个长岩心，这是一个关键地点，在这里，输出的北大西洋深水沃茨的物理和地球化学性质是由北方和南方深海水体混合而成的。该研究旨在为末次冰期-间冰期旋回建立深海型深水环流剖面。该研究计划包括对活塞岩心进行详细的地层调查，以及对过去16万年来深水循环和地表水状况的几个一阶代理的初步测量。合作工作计划包括一套分析，其中包括扫描X射线分析、放射性碳和稳定同位素分析、微量元素分析、铀系列分析以及从沉积物中汇编新大陆记录。更广泛的影响涉及研究生和本科生以及一名高中生的教育和培训。这项研究的结果将适用于课程和讲座。这些数据将存档，供今后进行古海洋学和古气候研究之用。

Funds are provided to analyze seven long cores recovered from the Bermuda Rise in the North Atlantic Ocean, a key location where the physical and geochemical properties of exported North Atlantic Deep Waters are set by mixing between the northern and southern abyssal water masses. The research aims to create an abyssal type section of deepwater circulation for the last glacial-interglacial cycle. The research plan includes detailed stratigraphic investigations of piston cores and the initial measurement of several first order proxies of deep water circulation and surface water conditions for the last 160,000 years. The collaborative work plan includes a suite of analyses that include scanning x-ray analyses, radiocarbon and stable isotopic analysis, trace and minor element analysis, Uranium series analyses, and compiling Neodymium records from sediments. The broader impacts involve the education and training of graduate and undergraduate students, and a high school student. Results from this research will be adapted for coursework and lectures. The data will be archived and available for future paleoceanographic and paleoclimate studies.
