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个海洋科学仪器开发项目，以开发和测试一种新的高容量、无管浮游动物收集泵系统，用于海上使用。该抽水系统(将命名为MEGAPUMP)旨在解决现有抽水系统的几个缺点。该装置将由安装在旋转木马收集装置上的水下泵组成。该泵将在前部安装一个短歧管，为10个旋转的过滤器收集管提供服务。一个步进电机将被用来通过远程驱动来“选择”下一个过滤器。整个配置将安装在钢笼中，以防止部署过程中的机械损坏。巨型飞机的电力供应将通过悬挂电缆提供。安装在泵上的环境传感器包括一个磁流量计和一个用于测量电导率、温度和深度的CTD。与以前的系统相比，该巨型系统将以更高的空间分辨率和深度容量促进浮游动物采样。使用该系统获得的样品将通过高分辨率采样来更好地了解浮游动物的微结构聚集。这一新能力将对目前和未来有关海洋浮游动物的研究具有重要意义。

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.
