The PIs propose to develop a hardware/software interface system that will allow the acquisition of various scientific data from a seafloor in observatory mode, using seafloor cables to provide power and communications. The main objective is to provide a system, based as much as possible on off-the-shelf technology, that will allow: connection of scientific instruments that are not in the immediate vicinity of a cable node and therefore require an extension cable, connection of multiple sensors with different interfaces (analog and digital), data rates, and other requirements to the extension cable, data acquisition as part of an existing continuous and real time monitoring system. There is a unique opportunity for this development with the conjunction of: the planned installation of the MARS cable and the proximity of the MARS cable path to the existing ocean floor broadband seismic MOBB station. This project will define, design, fabricate, and install the interfaces necessary to have MOBB installed on the MARS cable to fully exploit the power of the existing instrumentation and the benefits provided by MARS. In particular, the PIs propose to adapt to the cabled observatory environment, the AUDL (Advanced Underwater Data Logger) electronics module currently being developed by GEOsense for autonomous seafloor deployments, as well as software for on-shore data acquisition and remote communication with the sensors on the seafloor. The components developed will then be available for connecting other seafloor sensors to MARS and for replication on other cables. The proposed system is based on a commercially available datalogger, a Science Instrument Interface Module (SIIM) that will be freely available to other users, and software for data telemetry and shore-based acquisition and data distribution software based on Freeorb. Borader ImpactsThis work is necessary if the OOI and other ocean observatory programs are to meet their potential. Its uses go far beyond the application proposed here. The educational impact was limited although these PIs have an excellent track record of including students in their funded work.

PI建议开发一个硬件/软件接口系统，该系统将允许以观测模式从海底获取各种科学数据，使用海底电缆提供电力和通信。主要目标是提供一个尽可能基于现成技术的系统，该系统将允许：连接不在电缆节点附近的科学仪器，因此需要延长电缆，连接具有不同接口的多个传感器（模拟的和数字的）、数据速率和对延长电缆的其它要求，数据采集作为现有的连续和真实的时间监控系统的一部分。有一个独特的机会，这一发展的结合：计划安装的火星电缆和火星电缆路径的接近现有的海底宽带地震MOBB站。该项目将定义、设计、制造和安装在MARS电缆上安装MOBB所需的接口，以充分利用现有仪器的功率和MARS提供的优势。特别是，PI建议适应有线观测环境，AUDL（高级水下数据记录仪）电子模块目前正在开发的GEOsense自主海底部署，以及软件的岸上数据采集和远程通信的传感器在海底。然后，开发的组件将可用于将其他海底传感器连接到MARS，并在其他电缆上复制。拟议系统的基础是一个商用数据记录器、一个将免费提供给其他用户的科学仪器接口模块（SIIM）、数据遥测软件和基于Freeorb的岸基采集和数据分发软件。如果OOI和其他海洋观测计划要发挥其潜力，这项工作是必要的。它的用途远远超出了这里提出的应用。教育的影响是有限的，虽然这些PI有一个良好的记录，包括学生在其资助的工作。
