Development of an an acoustic data storage tag for long range fish tracking in the ocean

P.I.Fischer(URI)提案#：0326907提案标题：在海洋项目摘要中开发用于远程鱼类跟踪的声学数据存储标签PI建议设计、制造和测试用于远程跟踪鲑鱼、鲨鱼和大西洋鳕鱼等鱼类的全功能声学数字存储标签。这些动物在其生命周期中远距离迁徙，然而，它们特定的迁徙模式很难确定。具体地说，PI建议制造一种DST，用于监听和记录从系泊声源发出的信号的准确到达时间。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，将使用在使用传统DST进行研究期间开发的技术将其附着在鱼类身上或植入鱼类体内。捕获后将从鱼中检索数据。如果是植入物，外部丝带或标记将提醒渔民标签的存在。根据特定物种的追踪条件(声道和水深)，可获得100至1000公里量级的声学探测范围，分辨率为几公里。PI设想标签由一个小型水听器组成，该水听器还将用作微型电路板、计时晶体、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。这项工作是从早期发展的纯温度DST发展而来的。PI已经联系了外部供应商，以确保最终从原型标签过渡到批量生产的设备。

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.
