.I. Shaw, Timothy (Univ. S. Carolina) Proposal #: 0327294Proposal Title: Development of a Pump Array for the Two Dimensional Mapping of Chemical Constituents in the Upper Water ColumnProject SummaryThe PI proposes to develop a towed pumping system, based on his successful prototype, for the collection of analytes from large volume samples at multiple depths in the upper water column. The system will be comprised of a series of pumps that will be deployed on a hydro wire and powered by a current driven propeller. Critical components include the power unit (pump), sampling stack, and control module (data logger, sample valve control). The data logger will record flow rate, integrated volume, as well as data from an external CTD. A propeller will power the pump as it is towed through the water column. The pump will pressurize the sampling stack to create flow through the selected filter/cartridge column to the flow meter in the data logger. The system will allow sequential sampling for up to ten intervals per unit during a single deployment while the ship is underway. The multi-sample capacity of each unit will mean that a single deployment will produce a two dimensional map of the analytes of interest. The individual pumps are designed to be inexpensive, and easily deployed from a hydro wire, making the system appropriate for large scale mapping of analytes of interest as well as local high-density sampling.

I.Shaw，Timothy(大学提案#：0327294提案标题：开发用于上层水柱化学成分二维测绘的泵阵列项目摘要PI建议在其成功原型的基础上开发一个拖曳抽水系统，用于从上层水柱多个深度的大量样品中收集分析物。该系统将由一系列泵组成，这些泵将部署在水力线上，并由电流驱动的螺旋桨提供动力。关键部件包括动力装置(泵)、采样堆和控制模块(数据记录器、采样阀控制)。数据记录器将记录流量、积分体积以及来自外部CTD的数据。当泵被拖过水柱时，螺旋桨将为其提供动力。泵将对采样堆叠加压，以产生流经所选过滤器/滤筒柱到数据记录器中的流量计的流量。该系统将允许在单次部署期间对每个单元进行最多10个间隔的顺序采样，同时船在航行。每个单位的多样本能力将意味着一次部署将产生感兴趣的分析物的二维图。每台泵的设计价格低廉，易于从电线上部署，使该系统适合于大规模绘制感兴趣的分析物地图以及本地高密度采样。
