"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)."CAPABLE (Coastal Autonomous Profiling and Boundary Layer System) development began three years ago under OTIC funding with a partnership between Oregon State University?s College of Oceanic and Atmospheric Sciences (COAS) and Western Environmental Technology Laboratories Inc. (WET Labs). This effort was initiated to design and build the next-generation, multi-parameter oceanographic sensing system. CAPABLE is equipped with sensors to measure ocean temperature, velocity, salinity, nitrate content, dissolved oxygen level, suspended particle load, and chlorophyll concentration. Knowledge of these parameters is critical to assessing the state of the coastal ecosystem and for monitoring changes due to natural and anthropogenic forcing. CAPABLE is aimed at fulfilling the need for autonomous profiling in coastal ocean observatories, including NSF?s Ocean Observatories Initiative. The existing CAPABLE system has been tested off Oregon in 50 m of water, demonstrating ability to cycle up-and-down using the electric winch mounted inside the X10 AMP, to compensate for surface wave heaving by software control, to recharge the X10 AMP batteries using an inductive charging system, and to offload data inductively. However, further engineering refinements and field testing are needed to make CAPABLE an operational system. The main goals of this renewal are to 1) demonstrate longer endurance, 2) fully populate and operate CAPABLE?s multi-parameter sensor suite, and 3) test survivability, profiler control and near real-time data acquisition in winter-time storm conditions. These goals will be accomplished by making mechanical and software modifications to the system. A series of four field tests over two years will be performed off the Oregon coast.

该奖项由2009年美国复苏与再投资法案(公法第111-5条)资助。三年前，在OTIC的资助下，俄勒冈州立大学S海洋与大气科学学院(COAS)和西部环境技术实验室公司(WET Labs)开始了CABLE(海岸自主轮廓和边界层系统)的开发。这项工作是为了设计和建造下一代多参数海洋遥感系统。Capable配备了传感器来测量海洋温度、速度、盐度、硝酸盐含量、溶解氧水平、悬浮颗粒物负荷和叶绿素浓度。了解这些参数对于评估沿海生态系统的状况和监测自然和人为强迫造成的变化至关重要。有能力的项目旨在满足沿海海洋观测站对自主剖面图的需求，包括美国国家科学基金会？S海洋观测站倡议。现有的有能力的系统已经在俄勒冈州附近50米的水下进行了测试，展示了使用安装在X10 AMP中的电动绞车进行上下循环的能力，通过软件控制补偿表面波起伏的能力，使用感应充电系统为X10 AMP电池充电的能力，以及感应卸载数据的能力。然而，还需要进一步的工程改进和现场测试，才能使操作系统具备能力。此次更新的主要目标是1)展示更长的耐用性，2)完全填充和操作能力？S多参数传感器套件，以及3)测试生存能力、剖面仪控制和冬季风暴条件下的近实时数据采集。这些目标将通过对系统进行机械和软件修改来实现。在两年的时间里，将在俄勒冈州海岸进行一系列四次实地测试。
