Asper 9413809 This award provides support for the acquisition of instrumentation to be used in the study of biological, chemical and geological particle flux in the marine environment. The primary use of the system is anticipated to be study of "marine snow," or particulate matter. While it is well known that marine particulates are an important agent in flux of many chemical species in the ocean, and thus a key element in understanding nutrient and other chemical cycling, the details of how these processes occur is not well understood. The PI is one of the leading researchers in this field. The specific instrumentation supported in this award is upgrades to the PI's existing, DepSCOR-supported "remotely operated vehicle," or ROV. These upgrades significantly improve the capabilities of the ROV, providing sufficient thrust to allow its operation in ocean currents, providing precise navigation fo it, and providing portable laboratory systems for both system operation on "ships of opportunity" and for carrying out chemistry on samples collected during shipboard programs. University of Southern Mississippi provides 30% cost sharing of the project, supported under the Advanced Research Initiatives program. ***

Asper 9413809该奖项为购置用于研究海洋环境中生物、化学和地质粒子通量的仪器提供支持。 预计该系统的主要用途是研究“海洋雪”或颗粒物质。 虽然众所周知，海洋微粒是海洋中许多化学物种流动的一个重要媒介，因此是了解营养和其他化学循环的一个关键因素，但对这些过程如何发生的细节还没有很好的了解。 PI是该领域的主要研究人员之一。 该合同中支持的具体仪器是对PI现有的、由DepSCOR支持的“远程操作飞行器”或“远程控制飞行器”的升级。 这些升级显着提高的能力，提供足够的推力，使其在洋流中运行，提供精确的导航，并提供便携式实验室系统的系统操作的“机会之船”和进行化学在船上程序期间收集的样品。 南密西西比大学提供该项目30%的费用分摊，由高级研究倡议计划支持。 ***
