Development of a Pump Array for the Two Dimensional Mapping of Chemical Constituents in the Upper Water Column

我。Shaw, Timothy （university . S. Carolina）提案#:0327294提案标题：开发用于上层水柱中化学成分二维映射的泵阵列项目摘要PI建议开发一种拖曳泵系统，基于他成功的原型，用于收集上层水柱中多个深度的大量样品中的分析物。该系统将由一系列泵组成，这些泵将部署在水力电缆上，由电流驱动的螺旋桨提供动力。关键组件包括动力单元（泵），采样堆栈和控制模块（数据记录仪，采样阀控制）。数据记录仪将记录流量、综合体积以及来自外部CTD的数据。当水泵被拖过水柱时，螺旋桨将为它提供动力。泵将对采样堆栈加压，通过选定的过滤器/滤筒柱将流量输送到数据记录仪中的流量计。该系统将允许在船舶航行期间的单次部署中对每个单元进行多达10次的连续采样。每个单元的多样本容量将意味着单个部署将产生感兴趣的分析物的二维地图。单个泵的设计价格低廉，并且易于从水力电线部署，使该系统适用于感兴趣的分析物的大规模测绘以及局部高密度采样。

.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.
