海洋科学仪器开发项目将 开发定时释放遥测数据舱， 系泊和底部安装的仪器，如海流计。 一 项目的目标是能够附加一个或多个数据 从胶囊到仪器，以供长期部署。 一个胶囊 控制器将压缩、编码和存储由 仪器 在某个预定时间，控制器将 启动释放装置使胶囊上升到水面， 它将通过卫星把存储的数据传送到岸上 通信连接。 各种数据编码和遥测 将开发基于微计算机的控制器的方案 并连接到现有数据记录器的选择。 仪器安装组件和膜盒释放机构 还将进行开发和实地测试。 这种数据胶囊的使用将提供后勤和科学 优于需要整个仪器的现有系统 在收集数据之前检索包。 在偏远 数据稀少且收集成本高的地理区域， 科学家可以部署长期仪器， 能够定期接收数据。 不仅有 表明仪器工作正常，但 还可以选择逐步分析数据， 根据接收到的信息改变实验设计。 数据 胶囊还提高了使用消耗性 具有一定经济优势的仪器。

This Ocean Sciences Instrumentation development project will develop a timed-release telemetering data capsule for use on moored and bottom-mounted instruments such as current meters. A goal for the project is the ability to attach one or more data capsules to instrumentation for long-term deployment. A capsule's controller will compress, encode, and store data collected by the instrument. At some predetermined time, the controller will activate a release enabling the capsule to rise to the surface, whereupon it will transmit the stored data ashore via a satellite communications link. Various data encoding and telemetring schemes for a micro-computer based controller will be developed and interfaced to a choice of existing data recorders. Instrumentation mounting assemblies and capsule release mechanisms will also be developed and field tested. The use of such data capsules will provide logistic and scientific advantages over present systems that require the entire instrument package to be retrieved before data is collected. In remote geographical areas where data is sparse and expensive to collect, long-term instrumentation could be deployed with the scientist being able to receive data periodically. Not only would there be an indication that the instruments were working properly, but there will also be the option of progressively analyzing data and altering experimental design based on received information. Data capsules also enhance the possibility of using expendable instrumentation that have certain economical advantages.
