P.I. Rognstad (UH) Proposal #: 0328252Proposal Title: Collaborative Research: Seafloor Sounding in Polar and Remote Regions The PIs propose to develop a Seafloor Sounding in Polar and Remote Regions (SSPARR) System that will enable seafloor depth soundings to be collected in regions rarely or never visited by ships. As proposed, the system will consist of a large number of expendable, battery-powered, surface drifting buoys, each containing a simple single beam depth sounder, a GPS navigation receiver, and a bi-directional satellite link. The system developed will also include the shore infrastructure to monitor the buoys, control their function and receive sounding data, perform quality checks, and archive the sounding data. The PIs will develop a system whereby the buoys could be deployed over the side of a ship or by air. They also propose that the SPARR buoy, enabled by the shore site, could be an aid to navigation for underwater vehicles, in which case the buoy will transmit its own GPS derived location via acoustic telemetry and these positions could be recorded by the underwater vehicle to aid in track reconstruction or for use in real-time navigation. This function is expected to be of particular use in remote areas where unmanned underwater vehicles may be employed for seafloor surveys. Buoys will be strategically deployed where prevailing currents will carry them into areas where depth soundings are required, and where ships seldom travel. The lifetime of a SSPARR buoy will be dependent upon repetition rate of acoustic and electromagnetic transmissions, but it is estimated that a typical buoy will have a lifetime of up to four years in echo-sounding mode and possibly only one year as a navigation aid. The PIs envision the development of SSPARR in three phases: A technology assessment and demonstration phase; full scale engineering development with parallel shore site implementation; and pilot buoy production. Test and evaluation efforts are inherent in all three phases. This proposal is the first of the three phases, technology assessment and demonstration. This effort will entail development of prototype hardware for testing in laboratory and at sea; and optimization of sonar parameters and communication protocols.

P.I. Rognstad（UH）提案＃：0328252 PROPOPASE标题：协作研究：PIS和偏远地区的海底发声PIS提议开发在Polar and Remotions（SSPARR）系统（SSPARR）系统中发出的海底系统，该系统将启用在sherips或从未访问的区域中可以收集的海底深度响起。如建议，该系统将由大量消耗的电池供电，表面漂流浮标组成，每个浮标都包含一个简单的单光束深度音器，GPS导航接收器和双向卫星链路。开发的系统还将包括用于监视浮标，控制其功能并接收声音数据，执行质量检查并归档发声数据的海岸基础架构。 PI将开发一个系统，可以将浮标部署在船的侧面或空中。他们还建议，由海岸现场启用的SPARR浮标可能有助于导航水下车辆，在这种情况下，浮标将通过声学遥测传输其自己的GPS位置，这些位置可以由水下车辆记录以帮助轨道注册型或用于实时导航。预计该功能将在偏远地区特别有用，那里的水下车辆可能用于海底调查。浮标将在战略上部署，在盛行的电流将它们带入需要深度响起的区域，并且很少旅行。 SSPARR浮标的寿命将取决于声学和电磁传输的重复率，但据估计，典型的浮标将在回声模式下最多四年，并且可能仅作为导航辅助工具。 PIS在三个阶段中设想了SSPARR的发展：技术评估和示范阶段；全尺度工程开发具有并行的海岸场地实施；和飞行浮标的生产。测试和评估工作都是所有三个阶段固有的。该提案是三个阶段中的第一个，即技术评估和演示。这项工作将需要开发原型硬件，以在实验室和海上进行测试；和声纳参数和通信协议的优化。
