Project SummaryThis project represents a partnership between Oregon State University and WET Labs to develop a Coastal Autonomous Profiling and Boundary Layer System (CAPABLE). This effort combines the experience of OSU scientists and technicians working in the coastal ocean with the engineering and oceanographic sensor expertise of WET Labs to design and build the next generation, multi-parameter oceanographic sensing system. CAPABLE will be equipped with sensors to measure the ocean temperature, velocity, salinity, nitrate content, dissolved oxygen level, suspended particle load, and chlorophyll concentration. CAPABLE will consist of three components: 1. The ExTended ENdurance Autonomous Moored Profiler (xTEN AMP) based on a winch-on-board design and carrying a suite of interdisciplinary sensors capable of profiling a 200 m water column 8 times per day. The system will telemeter data to shore via radio or Iridium phone and be deployable for 6 months. The xTEN AMP will carry a battery pack capable of being recharged from a power system housed in a bottom-mounted docking station; 2. The Shallow Coastal Upward Looking Profiler Integration Node (SCULPIN) housing the battery recharge system, a deployment/recovery system and a set of instruments for making measurements in the bottom boundary region below the xTEN AMP's lowest measurement. The SCULPIN instrument suite includes an upward-looking acoustic Doppler current profiler to obtain high-resolution velocity profiles, and sensors to measure near-bottom pressure, temperature, conductivity, chlorophyll concentration, and suspended particle load; 3. The Surface Boundary Buoy (SBB) making detailed observations in the air and the upper-ocean region, using a suite of meteorological sensors, a high-frequency acoustic Doppler profiler and sensors to measure upper-layer temperature-conductivity to resolve the upper-ocean structure. The SBB also provides a platform for collecting and telemetering all data to shore. The xTEN AMP will cycle up-and-down through the water column using an electric winch mounted inside the profiling platform rather than on the ocean bottom. The xTEN AMP will feature: a completely self-contained, modularly-integrated sensor, instrument controller, winch, power and telemetry system; a biofouling-resistant and hydrodynamic profiling platform; an intelligent winch controller for dynamic profiling; and an inductive charging system coupling with the SCULPIN. The xTEN AMP will communicate acoustically with the SBB and through an inductive system with the SCULPIN sensors. Data will be sent to shore via HF radio or satellite phone from the xTEN AMP and/or from the SBB. Data will then be sent on the Internet to OSU for data processing, quality control, archiving, and posting on a web portal. As a backup, all data will be stored internally on the xTEN AMP, SCULPIN and SBB.

该项目代表了俄勒冈州立大学和WET实验室之间的合作伙伴关系，以开发沿海自主剖面和边界层系统（CAPABLE）。这项工作将俄勒冈州立大学科学家和技术人员在沿海海洋工作的经验与WET实验室的工程和海洋传感器专业知识结合起来，设计和建造下一代多参数海洋传感系统。CAPABLE将配备传感器来测量海洋温度、速度、盐度、硝酸盐含量、溶解氧水平、悬浮粒子负荷和叶绿素浓度。CAPABLE将由三个部分组成：1。ExTended ENdurance自主系泊剖面仪（xTEN AMP）基于船载绞车设计，携带一套跨学科传感器，能够每天对200米水柱进行8次剖面分析。该系统将通过无线电或铱星电话将数据遥测到岸上，并可部署6个月。xTEN AMP将携带一个电池组，能够从安装在底部的对接站中的电源系统充电；2. 浅海上向剖面仪集成节点（SCULPIN）包含电池充电系统、部署/回收系统和一组仪器，用于在xTEN AMP最低测量值以下的底部边界区域进行测量。SCULPIN仪器套件包括一个向上看的声学多普勒电流分析器，用于获得高分辨率的速度剖面，以及测量近底部压力、温度、电导率、叶绿素浓度和悬浮颗粒负载的传感器；3. 表面边界浮标（SBB）在空中和上层海洋区域进行详细观测，使用一套气象传感器、高频声波多普勒分析器和传感器来测量上层温度-电导率，以解析上层海洋结构。SBB还提供了一个收集和遥测所有数据到岸上的平台。xTEN AMP将使用安装在剖面平台内的电动绞车在水柱中上下循环，而不是安装在海底。xTEN AMP将具有：完全独立，模块化集成的传感器，仪表控制器，绞车，电源和遥测系统；抗生物污染和流体动力剖面平台；智能卷扬机动态轮廓控制器以及与SCULPIN耦合的感应充电系统。xTEN AMP将通过带SCULPIN传感器的感应系统与SBB进行声学通信。数据将通过高频无线电或卫星电话从xTEN AMP和/或SBB发送到岸上。然后，数据将通过Internet发送到俄勒冈州立大学进行数据处理、质量控制、存档和在门户网站上发布。作为备份，所有数据将存储在xTEN AMP， SCULPIN和SBB内部。
