Development of a Moored Vertically Profiling Video Plankton Recorder

9406361加拉格尔伍兹霍尔海洋研究所将承担一个海洋科学仪器开发项目，以设计、建造和测试系泊垂直剖面浮游生物录像机，该录像机将确定浮游动物的分类和大小组成，以及几个环境变量，从几个小时到几个月的时间尺度。该系统是围绕一个浮力流线型机身设计的，该机身包含VPR和相关的电子设备以及传感器，这些传感器将由底部安装的绞车升降。绞车将允许VPR快速上升到表面，然后在进行测量和记录数据的同时将系统缓慢拉回地面。我们的目标是能够在100米的深度内每次部署最多300个配置文件，同时记录来自两个摄像头的视频信号，以及传导性、温度、深度荧光、光传输和井下辐照度。浮游动物和100微米至5厘米大小的颗粒将被数字化减少和记录。与从研究船获取类似数据的成本相比，在公海区域使用这种系统是获得长时间序列数据的一种具有成本效益的方式。

9406361 Gallager Woods Hole Oceanographic Institution will undertake an ocean sciences instrument development project to design, construct, and test a moored vertically profiling Video Plankton Recorder (VPR) that will determine the taxonomic and size composition of zooplankton, along with several environmental variables, over time scales of hours to months. The system is designed around a buoyant streamlined body containing the VPR and associated electronics plus sensors that will be raised and lowered by a bottom-mounted winch. The winch will allow the VPR to ascent rapidly to the surface and then will pull the system back down slowly while it makes measurements and records data. The goal is to be able to make up to 300 profiles per deployment in depths of up to 100 meters, while recording a video signal from two cameras, plus conductivity, temperature, depth fluorescence, light transmission, and downwellig irradiance. Zooplankton and particles within the size range of 100 microns to 5 centimeters will be reduced digitally and recorded. The use of such a system in open ocean regions represents a cost- effective way of obtaining long-time series data, compared to the cost of obtaining similar data from a research vessel.
