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.

9504021俄勒冈州立大学米勒大学将开展一项海洋科学仪器开发项目，以开发和测试新的高容量，无霍斯的浮游动物，收集泵系统，以便在海上使用。 泵送系统（命名为MegaPump）旨在解决现有的抽水系统的几个缺点。 该装置将由安装在旋转木马收集单元上的水下泵组成。 该泵将用短流形的形式安装在前面，该歧管提供10个旋转过滤器收集管。 通过远程致动，将使用踏脚电机来“选择”下一个过滤器。 总体配置将安装在钢笼中，以防止部署过程中的机械损坏。 巨型电源将通过悬架电缆进行。 要连接到泵的环境传感器包括磁流量计和用于测量电导率，温度和深度的CTD。 与以前的系统相比，巨型将促进具有更大空间分辨率和深度容量的浮游动物采样。 使用该系统获得的样品将通过高分辨率采样来更了解浮游动物的微观结构聚集。 这种新功能对于涉及海洋浮游动物的当前和未来调查将很重要。
