P.I. Fischer (URI) Proposal #: 0326907Proposal Title: Development of an acoustic data storage tag for long-range fish tracking in the oceanProject Summary The PIs propose to design, fabricate, and test a fully functional acoustic Digital Storage Tag for long-range tracking of fish such as salmon, shark and Atlantic cod. These animals migrate over great distances in the course of their life cycles however, their specific migration patterns are difficult to ascertain. Specifically, the PIs propose to fabricate a DST that will listen for and record the exact arrival times of signals emitted from moored sound sources. To obtain additional habitat information, the tag will also periodically record pressure and temperature. The devices, having a design lifetime of two years, would be attached to or implanted in fish using techniques developed during studies using conventional DSTs. The data will be retrieved from the fish upon capture. In case of an implant, an external ribbon or marker would alert fishermen to the presence of the tag. Acoustic detection ranges on the order of 100 to 1,000 km could be obtained with a resolution of a few kilometers, depending upon the tracking conditions (sound channel and water depth) for a given species. The PIs envision the tags to consist of a small hydrophone that will also serve as the housing for the miniature circuit board, timing crystal, pressure sensor, and battery. Prior to deployment, the tag will be programmed from a host PC via a serial communication interface. This work evolves from an earlier development of a temperature-only DST. The PIs have already contacted external vendors to ensure that there is an eventual transition from a prototype tag to a mass produced device.

P.I. Fischer（URI）提案编号：0326907提案标题：开发用于海洋中远程鱼类跟踪的声学数据存储标签项目摘要PI建议设计、制造和测试用于远程跟踪鱼类（如鲑鱼、鲨鱼和大西洋鳕鱼）的全功能声学数字存储标签。这些动物在其生命周期中迁徙很远，但其具体的迁徙模式很难确定。具体来说，PI建议制造一个DST，它将监听和记录从系泊声源发出的信号的确切到达时间。为了获得更多的栖息地信息，标签还将定期记录压力和温度。这些装置的设计寿命为两年，将使用传统DST研究期间开发的技术连接或植入鱼类。数据将在捕获后从鱼中检索。在植入的情况下，外部丝带或标记将提醒渔民标签的存在。声波探测距离可达100至1 000公里，分辨率为几公里，视特定物种的跟踪条件（声波通道和水深）而定。PI设想的标签包括一个小型水听器，也将作为微型电路板，定时晶体，压力传感器和电池的外壳。在部署之前，将通过串行通信接口从主机PC对标签进行编程。这项工作是从一个早期发展的温度只有DST。PI已经联系了外部供应商，以确保最终从原型标签过渡到大规模生产的设备。
