0652430Duennebier This award to University of Hawaii at Manoa provides support for the completion and deployment of the ALOHA Cabled Observatory (ACO). ACO is intended to expand the scientific infrastructure at the location of the Hawaii Ocean Time-series (HOT) site near Hawaii, and to demonstrate that existing, retired fiber optic telecommunications cables can be successfully reused to support scientific ocean observatories. The proposal builds on work undertaken with funds provided in 2002 via the MRI program (0216164) that was originally intended to develop an observatory using a coaxial telecommunications cable, but was not possible due to the bankruptcy of the owner and inability to negotiate a transfer of the cable. The opportunity to use the fiber optic cable came up subsequently, and observatory design and proof testing has been completed in the laboratory and through the cable (but not in the water). Deployment of the Proof Module off Hawaii is currently planned for February 2007. It will test power supply, optical regeneration and observatory electronics, and will include a broad-band hydrophone that can sample up to 96 kHz as well as a pressure sensor. On completion of a successful deployment and testing of the Proof Module, it will be recovered and replaced in late 2007 with an operational observatory system and the first batch of scientific instruments for continuous observations and oceanographic experiments. The observatory will support up to eight experiment systems with 100base-T Ethernet data and up to 800 W power. One experiment module will be an acoustic modem so that experimental modules may be deployed near the cable, but not attached directly, which will offer an opportunity for additional experiments operating with lower speed communication for the transmission of information to shore. Broader Impacts: Support provided here will provide an infrastructure for continuous access to a broad array of oceanographic data at Station ALOHA by students and researchers on shore via high speed telecommunications cable. Station ALOHA is already an important time-series station of ocean observations, with over 18 years of data collected by regular ship observations, and the expansion to include continuous data collected and relayed to shore is a major augmentation. In addition, the ALOHA Cabled Observatory serves as a prototype and test bed for deep ocean observatories, using abandoned fiber-optic telecommunications cables to support ocean research.***

0652430杜内比尔 授予马诺阿夏威夷大学的这一奖项为ALOHA有线观测台（ACO）的完成和部署提供了支持。 ACO的目的是扩大夏威夷附近的夏威夷海洋时间序列（HOT）站点的科学基础设施，并证明现有的退役光纤电信电缆可以成功地重新用于支持科学海洋观测站。 该提案建立在利用2002年通过MRI计划（0216164）提供的资金进行的工作的基础上，该计划最初打算使用同轴电信电缆开发一个观测站，但由于所有者破产和无法谈判电缆转让而无法实现。 随后出现了使用光纤电缆的机会，观测台的设计和验证测试已经在实验室和通过电缆（但不是在水中）完成。 目前计划于2007年2月在夏威夷外海部署验证模块。 它将测试电源、光学再生和观测电子设备，并将包括一个可采样高达96 kHz的宽带水听器以及一个压力传感器。 在成功部署和测试验证模块后，将于2007年晚些时候收回该模块，代之以一个运行中的观测系统和第一批用于连续观测和海洋学实验的科学仪器。天文台将支持多达8个实验系统，100 base-T以太网数据和高达800 W的功率。 一个实验模块将是声学调制解调器，以便实验模块可以部署在电缆附近，但不直接连接，这将为以低速通信操作的附加实验提供机会，以便将信息传输到海岸。更广泛的影响：这里提供的支助将提供一个基础设施，使海岸上的学生和研究人员能够通过高速电信电缆不断获取ALOHA站的各种海洋学数据。 ALOHA站已经是一个重要的时间序列海洋观测站，通过定期船舶观测收集了18年以上的数据，扩大到包括连续收集的数据并传送到海岸是一个重大的扩充。 此外，ALOHA有线观测台是深海观测台的原型和测试台，使用废弃的光纤电信电缆支持海洋研究。
