The PI's propose to develop a Networked Oceanographic Sensor Array (NOSA), an instrument frame with a well-defined Ethernet interface that will operate as a network object in the marine environment. Its small size and low power consumption will make NOSA deployable on a variety of existing, and emerging platforms, including cabled seafloor and moored observatories, moorings, remotely-operated/autonomous underwater vehicles (ROVs, and AUVs), floats, and gliders. The instrument functionality will be defined by a set of plug-and-play sensors carried in standardized sensor sockets. The instrument frame will be equipped with a 32-bit processor running Linux and Java, and will operate as a field-reconfigurable remote sensor server. The object-based communication software will allow access to the instrument using a standardized set of object methods and properties, common for all the NOSA-compliant sensors, and the instrument data will be distributed in XML (eXtended Markup Language), or netcdf format.The nonproprietary, well-defined and documented mechanical/electrical architecture of NOSA will allow development of future sensors by a third party, promoting development of a new family of instruments. These instruments will be easily adaptable to specific applications and requirements, by simply modifying the sensor configuration, while maintaining the generic character of the NOSA electronics and software. The open software architecture will permit an implementation-independent interface, simplifying the logistics of instrumenting a vide variety of observational programs. The first implementation of the proposed NOSA instrument will carry a Fast Repetition Rate Fluorometer (FRRF) sensor to measure photosynthetic pigments and to characterize oxygenic/anoxygenic photosynthesis, a dissolved oxygen sensor, and a pCO2/pH sensor. In this configuration the instrument will measure the most critical chemical/biological properties related to the carbon and energy cycle in the ocean.

PI建议开发网络化海洋传感器阵列（NOSA），这是一种具有明确定义的以太网接口的仪器框架，将在海洋环境中作为网络对象运行。其小尺寸和低功耗将使NOSA可部署在各种现有和新兴平台上，包括海底电缆和系泊观测站，系泊设备，远程操作/自主水下航行器（ROV和AUV），浮子和滑翔机。仪器的功能将由一组即插即用的传感器定义，这些传感器安装在标准化的传感器插座中。仪器框架将配备一个运行Linux和Java的32位处理器，并将作为一个现场可重新配置的遥感器服务器运行。基于对象的通信软件将允许使用一组标准化的对象方法和属性访问仪器，这些方法和属性对于所有符合NOSA的传感器都是通用的，并且仪器数据将以XML形式分发（eXtended Markup Language）或netcdf格式。NOSA的非专有、明确定义和文档化的机械/电气架构将允许第三方开发未来的传感器，促进开发新的仪器系列。通过简单地修改传感器配置，这些仪器将很容易适应特定的应用和要求，同时保持NOSA电子和软件的通用特性。开放的软件架构将允许实现独立的接口，简化了各种观测程序的仪器化的物流。拟议的NOSA仪器的第一个实施将携带一个快速重复率荧光计（FRRF）传感器，以测量光合色素和表征氧/缺氧光合作用，溶解氧传感器和pCO 2/pH传感器。在这种配置中，该仪器将测量与海洋中的碳和能量循环有关的最关键的化学/生物特性。
