This Small Business Innovation Research (SBIR) Phase I project will provide the foundation for the technical development of a commercially viable, universal, data logging system for ultra-long duration, unattended, oceanographic measurements. The project will demonstrate a new electronic architecture for oceanographic data loggers. This advanced data logger will unify a highly fragmented commercial marketplace by offering best-of-class performance in nearly all oceanographic applications. The proposed technology employs a modular approach in which individual recording units utilize low-voltage, embedded, digital processors which are optimized specifically for their power performance. The complete recording system promises to have a power consumption that is an order of magnitude lower than existing systems, over a wide range of data rates. The logger will provide large volume mass storage and a non-volatile real-time clock. The system will implement both advanced power conversion and a high-speed communications interface, which will provide compatibility with both stand-alone and cabled applications in future seafloor observatories. Among the activities in Phase I, the project will develop and demonstrate the design for a critical component in the overall system, a 24 bit, ultra-low-power digitizer for seismic recording. A complete data logger built around this module will require less than 5 mW/channel.The commercial application of this logger will be in oceanographic research and exploration. The endemic model in oceanography is to customize off-the-shelf hardware for each specific application. This is a costly process. Many types of highly custom systems are developed and produced in small numbers, at great cost. This approach also presents a major schedule risk for the scientists involved. Not surprisingly, the operational performance of the resulting systems is suboptimal. Often, the diversion of resources for the development of instrumentation affects the scope and quality of the field research. By addressing a wide range of applications using a single, unified system, production volumes would be made large enough to reduce hardware costs significantly. Fundamental improvements to the logger's software will reduce the operational costs typically associated with customization of the system for each experiment. Reduction of both the equipment and operating costs will provide lower cost solutions for unattended oceanographic data acquisition. Reduction of the total cost of instrumentation is a critical step toward enhancing research efforts in many of the world's oceans.

该小型企业创新研究（SBIR）第一阶段项目将为商业上可行的通用数据记录系统的技术开发提供基础，用于超长持续时间，无人值守的海洋测量。该项目将展示一种新的海洋学数据记录仪电子结构。这款先进的数据记录仪将通过在几乎所有海洋应用中提供一流的性能来统一高度分散的商业市场。所提出的技术采用模块化方法，其中各个记录单元利用专门针对其功率性能进行优化的低压嵌入式数字处理器。完整的记录系统承诺在宽范围的数据速率上具有比现有系统低一个数量级的功耗。记录器将提供大容量存储和非易失性实时时钟。该系统将实现先进的功率转换和高速通信接口，这将在未来的海底观测站中提供独立和有线应用的兼容性。在第一阶段的活动中，该项目将开发和演示整个系统中一个关键组件的设计，这是一个用于地震记录的24位超低功耗数字化仪。以该模块为核心构建的完整数据记录仪每通道功耗小于5mW，可用于海洋研究和勘探。海洋学的特有模式是为每一种具体应用定制现成的硬件。这是一个昂贵的过程。许多类型的高度定制系统都是以很高的成本开发和生产的。这种方法也给参与的科学家带来了重大的日程风险。毫不奇怪，由此产生的系统的操作性能是次优的。通常，将资源转用于开发仪器会影响实地研究的范围和质量。通过使用单个统一的系统来处理各种应用程序，生产量将足够大，以显著降低硬件成本。对记录仪软件的根本性改进将降低通常与每次实验的系统定制相关的运营成本。设备和操作成本的降低将为无人值守的海洋数据采集提供更低成本的解决方案。降低仪器总成本是加强世界许多海洋研究工作的关键一步。
