The PIs propose to develop and deploy a moored battery pack/communication system that will enable profiling vehicles to measure profiles of temperature (T), salinity (S), velocity, and dissolved oxygen from 80-2500 m each 1.5 hours. The profiler to be used is a tested technology that has the potential to greatly remedy the current gross under-sampling of the ocean. Battery power still limits its endurance: one must either forego resolution of timescales 1 day, or limit total mission length to 46 days. The proposed system will replace the power and communications available from the cabled junction box, allowing the profiler to be used to deliver year-long, internal-wave-resolving profiles at any location. Charging will take 4 hours each 4 days. Two-way Iridium communications will allow real-time data access and upload of commands for adaptive sampling. Broader ImpactsThe broader impacts of the work include the ability to collect high-resolution profiles over extended periods will provide a much-needed tool for understanding a broad range of phenomena in the ocean including but not limited to productivity, carbon cycle and meso-scale circulation. These extended life profilers will be an important asset for remote moorings and well as a key component of cabled observatories.

PI建议开发和部署一个系泊电池组/通信系统，使剖面探测器能够每1.5小时测量80-2500米的温度（T）、盐度（S）、速度和溶解氧的剖面。将使用的剖面仪是一项经过测试的技术，有可能大大纠正目前对海洋采样严重不足的情况。电池电量仍然限制了它的续航时间：要么放弃1天的时间尺度，要么将总使命长度限制为46天。拟议的系统将取代电缆接线盒提供的电力和通信，使剖面仪能够在任何地点提供长达一年的内波解析剖面。每4天充电需要4小时。双向铱通信将允许实时数据访问和上传自适应采样命令。这项工作的更广泛影响包括在较长时期内收集高分辨率剖面的能力，将为了解海洋中的各种现象提供急需的工具，包括但不限于生产力，碳循环和中尺度环流。这些延长寿命的剖面仪将成为远程系泊的重要资产，也是有线观测站的关键组成部分。
