An Electro-Optical Cable Linking a Shore Laboratory with Observing Capabilities on the Continental Shelf off New Jersey

罗格斯大学海洋与海岸科学研究所（IMCS）和伍兹霍尔海洋研究所（WHOI）的海洋系统实验室（OSL）将合作安装一个长期水下观测系统，该系统通过电光电缆将远程操作的海底观测站与岸上实验室/控制站连接起来。长期生态系统观测站-15 （LEO-15）将在罗格斯大学海洋野外站（RUMFS）的近海建立。一条电子光缆将从新泽西州小蛋湾附近的RUMFS埋到大陆架上约10公里处，然后连接到大陆架上两个地点的两个初始平台。这种性质的系统将在很长一段时间内为相互连接的海洋传感器和车辆提供远程操作控制。埋地海底电缆将为许多海底系统提供电力和实时、宽带、双向通信。通过一些日常维护，可以开发出一个可靠的长期系统并投入使用。LEO-15设施的成功安装和运行将提供必要的工程经验和动力，以便将该系统扩展到更深的水域，并在全世界沿海和深水地区安装更多的场址。该系统将同时提供来自广泛传感系统的实时数据，时间尺度从秒到年，空间尺度从毫米到半径100米的电缆节点，以及自主水下航行器（auv），以公里为单位。来自LEO-15的数据可用于1)校准来自地球轨道卫星的信息；2)测量底栖边界层与海岸环流耦合模式的边界条件；3)监测与上升流、浮游生物繁殖、底栖生物通量、沉积物运输和跨海运输有关的过程的原位实验；4)研究商业鱼类和贝类的行为、补充和死亡来源。海洋和海岸科学研究所已承诺进行一项利用天文台的长期研究，并对该项目作出了大量的财政承诺。

9314823 Grassle The Rutgers University Institute of Marine and Coastal Sciences (IMCS) and the Oceanographic Systems Laboratory (OSL) of the Woods Hole Oceanographic Institution (WHOI) will collaborate and install a long-term underwater observing system that connects remotely- operated seafloor observatories with shore-based laboratories/ control stations via an electro-optical cable. The Long-term Ecosystem Observatory-15 (LEO-15) will be established offshore from the Rutgers University Marine Field Station (RUMFS). An electro- optical cable will be buried from RUMFS, near Little Egg Inlet, NJ to about 10 km out onto the continental shelf, thence to two initial platforms at two sites on the continental shelf. A system of this nature will provide remote operational control of intercon- nected ocean-based sensors and vehicles for an extended period of time. The buried seafloor cable will provide electrical power and real-time, broad bandwidth, bi-directional communication to a number of seafloor based systems. With some routine maintenance, a reliable long-term system can be developed and put into opera- tion. The successful installation and operation of the LEO-15 facility will provide the engineering experience and motivation necessary to expand this system into deeper water, and to install additional sites, worldwide, in both coastal and deep-water. The system will provide simultaneous real-time data from a broad array of sensing systems on time scales from seconds to years and spatial scales from millimeters to within radii of 100 m of nodes along the cable and, with autonomous underwater vehicles (AUVs), to kilometers. Data from LEO-15 may be used 1) to calibrate informa- tion from earth-orbiting satellites; 2) to measure boundary condi- tions for coupled benthic boundary layer and coastal circulation models; 3) to monitor in situ experiments on processes related to upwelling, plankton blooms, benthic flux, sediment transport and cross-s helf transport, and 4) to study the behavior, recruitment, and sources of mortality in commercial fish and shellfish species. The Institute of Marine and Coastal Sciences has committed to a long-term research that would utilize the Observatory, and has made a substantial financial commitment to the project as well.
