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.

小行星9314823 罗格斯大学海洋和海岸科学研究所和伍兹霍尔海洋学研究所海洋学系统实验室将合作安装一个长期水下观测系统，通过一条光电电缆将遥控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。 一条电光电缆将从新泽西州小蛋湾附近的RUMFS埋设到大陆架上约10公里处，从那里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对相互连接的海洋传感器和飞行器进行远程操作控制。 埋地海底电缆将为许多海底系统提供电力和实时、宽带宽、双向通信。 通过一些日常维护，可以开发可靠的长期系统并投入运行。 LEO-15设施的成功安装和运营将提供将该系统扩展到深水并在全球沿海和深水安装更多站点所需的工程经验和动力。 该系统将从一系列传感系统中同时提供实时数据，时间尺度从几秒到几年，空间尺度从毫米到沿电缆沿着100米半径的节点，以及自主水下航行器（AUV）到公里。 LEO-15的资料可用于1）地球轨道卫星资料的校正，2）测量耦合的海底边界层和海岸环流模式的边界条件; 3）监测与上升流、浮游生物大量繁殖、底栖通量、沉积物输运和交叉螺旋输运有关的过程的现场实验，以及4）研究行为、补充、以及商业鱼类和贝类的死亡来源。 海洋和海岸科学研究所已承诺利用该观测站进行长期研究，并已为该项目作出大量财政承诺。
