A Time or Event Triggered Automated, Serial Plankton Pump Sampler

这个海洋科学仪器开发项目将生产一个时间或事件触发的自动连续浮游生物泵采样器（ASPP）。该系统将被设计用于收集一系列浮游生物样本，从近地表到海底，在精细的空间尺度和各种流动状态下。朗赫斯特-哈迪浮游生物记录仪将收集并储存实际样本。系统的控制功能将是可编程的，并且还将根据机载物理传感器或外部获取的数据监测的特定条件进行操作。该系统将部署在水下系泊处进行水柱研究，或安装在底部进行底栖生物调查。ASPP的开发是为了满足长期以来对时间序列数据的生物采样需求，这些数据是独立于传统的网络和泵送系统收集的。将特别注意设计样品收集器配置，以尽量减少由不同流动环境引起的采样误差。该系统将在NSF计划的某些即将到来的科学项目中特别有用。

This ocean sciences instrumentation development project will produce a Time- or Event Triggered Automated Serial Plankton Pumping sampler (ASPP). The system will be designed to collect a series of plankton samples from the near surface to the seafloor at fine spacial scales and in a variety of flow regimes. A Longhurst-Hardy plankton recorder mechanism will collect and store the actual samples. The system's control functions will be programmable and will also operate in response to specified conditions monitored by either on board physical sensors or externally obtained data. The system will be deployable on a sub-surface mooring for water column studies, or bottom-mounted for benthic investigations. ASPP development is in response to long-standing biological sampling requirements for time-series data that is gathered independently of traditional net and pumping systems. Special attention will be given to designing the sample collector configuration to minimize sampling errors resulting from different flow environments. The system will be especially useful on certain upcoming scientific initiatives planned by NSF.
