Development of a Hoseless, High-Capacity Pumping System for Rapid, Multiple-Depth Sampling of Marine Zooplankton

9504021米勒俄勒冈州立大学将承担一项海洋科学仪器开发项目，开发和测试一种新的高容量、无软管的浮游动物收集泵系统，用于海上。该泵送系统（将被命名为MEGAPUMP）旨在解决现有泵送系统的几个缺点。该装置将由安装在旋转收集装置上的水下泵组成。该泵将与一个短歧管，服务于10个旋转过滤器收集管前置安装。步进电机将通过远程驱动来“选择”下一个滤波器。整体配置将安装在一个钢笼中，以防止在部署过程中机械损坏。电源供应到MEGA将通过悬挂电缆。安装在泵上的环境传感器包括一个磁性流量计和一个CTD，用于测量电导率、温度和深度。MEGA将以比以前的系统更大的空间分辨率和深度容量促进浮游动物取样。使用该系统获得的样品将允许通过高分辨率采样对浮游动物的微观结构聚集有更深入的了解。这种新的能力对于目前和未来涉及海洋浮游动物的研究将是重要的。

9504021 Miller Oregon State University will undertake an ocean sciences instrumentation development project to develop and test a new high-capacity, hoseless zooplankton collecting pump system for use at sea. The pumping system (to be named MEGAPUMP) is designed to address several shortcomings with existing pumping systems. The unit will consist of an underwater pump mounted on a carousel collection unit. The pump will be front mounted with a short manifold that serves 10 rotating filter collection tubes. A stepping motor will be used to "select" the next filter by remote actuation. The overall configuration will be mounted in a steel cage to prevent mechanical damage during deployment. Power supply to the MEGA will be via the suspension cable. Environmental sensors to be attached to the pump include a magnetic flow meter and a CTD for measuring conductivity, temperature and depth. The MEGA will facilitate zooplankton sampling with greater spatial resolution and depth capacity than previous systems. The samples obtained using this system will allow for a greater understanding of microstructure aggregation of zooplankton through high resolution sampling. This new capability will be important for current and future investigations involving oceanic zooplankton.
