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) 提案编号：0328252 提案标题：合作研究：极地和偏远地区海底探测 PI 提议开发极地和偏远地区海底探测 (SSPARR) 系统，该系统将能够在极地和偏远地区海底探测很少或很少的区域收集海底深度探测。从未有船只访问过。根据提议，该系统将由大量电池供电的消耗性表面漂流浮标组成，每个浮标包含一个简单的单波束测深仪、一个 GPS 导航接收器和一个双向卫星链路。开发的系统还将包括岸上基础设施，用于监控浮标、控制其功能并接收探测数据、执行质量检查以及存档探测数据。 PI 将开发一种系统，使浮标可以部署在船舷或空中。他们还提出，岸上启用的 SPARR 浮标可以为水下航行器提供导航辅助，在这种情况下，浮标将通过声学遥测传输其自己的 GPS 导出位置，并且水下航行器可以记录这些位置帮助轨迹重建或用于实时导航。该功能预计在可能使用无人水下航行器进行海底勘测的偏远地区特别有用。浮标将战略性地部署在盛行洋流将其带到需要测深且船舶很少航行的区域的地方。 SSPARR 浮标的使用寿命将取决于声学和电磁传输的重复率，但据估计，典型浮标在回声探测模式下的使用寿命可达四年，而作为导航辅助设备的使用寿命可能仅为一年。 PI 设想 SSPARR 的开发分三个阶段：技术评估和示范阶段；全面的工程开发与并行岸上站点实施；和试点浮标生产。测试和评估工作是所有三个阶段所固有的。该提案是技术评估和示范三个阶段中的第一阶段。这项工作将需要开发用于实验室和海上测试的原型硬件；声纳参数和通信协议的优化。
