ABSTRACTThis project expands on the goals of the LOOKING project funded through the ITR Program. The PIs request support to investigate and advance the utility of cyber-infrastructure in remote environments taking advantage of two significant opportunities; a submarine volcano oriented field program in the NE Pacific occurring at the same time as a major computing and communication show-case, iGrid, taking place in San Diego. The PIs propose to take an early step toward routine, remote use of High Definition TV for real-time inquiry into complex seafloor ecosystems using a combined Keck-NSF-UW supported research cruise in September 2005. On this cruise, HDTV imagery of vigorous seafloor hydrothermal systems will be transmitted from the JASON Remotely Operated Vehicle (ROV) to the R/V Thomas G. Thompson, from the Thompson to UWTV in Seattle, then to iGrid in San Diego. The scientific research will focus on a suite of hydrothermal fields that represent one of the most vigorously venting areas known along the global mid-ocean ridge spreading network. It hosts hundreds of black smokers on many tens of sulfide structures that rise 20 to 30 m above the seafloor. The vent systems support richly diverse, chemosynthetic biological communities. The HDTV signal from the seafloor will be recorded on board the Thompson, where a field production crew will simultaneously record coincident scientific dialogues guiding the research focused on linkages among earthquake activity, hydrothermal output, and sub seafloor microbial productivity. A blended and compressed version of both seafloor and surface-ship live feeds will be transmitted via the Galaxy 10R Satellite to the UWTV Studio. At UW, the uncompressed imagery from sea will be mixed, with a third HDTV stream with a group of land-based students, researchers and REVEL teachers interacting via back-channel audio communications with the scientists at sea. The three full bandwidth video streams, and a continuously updated stream of contextual material, will be transmitted to the iGrid Conference. In anticipation of new research infrastructure being developed within the Ocean Observatory Initiative (OOI) and in keeping with iGrid tradition, the goals of this prototype effort are to demonstrate, for the first time: 1) the feasibility and utility of transmitting live, interactive high-definition imagery from the deep sea for conducting remote research involving land-based participants; 2) the utility and importance of pushing the envelope on bandwidth, signal quality, and feedback mechanisms required to capture the dynamics of complex remote environments for widespread distribution to land-based audiences, and; 3) the powerful potentials for follow-on programs leading to real-time, 3-D use of HDTV streams opening exciting new research and outreach opportunities for remote, precision operations upon arrival of cabled observatories. This is cutting-edge risky project that could Broader Impacts:The convergence of many technologies that will be investigated in this proposal will empower scientists and educators from a broad range of disciplines and allow them to examine planetary-to-microbial scale system dynamics in remote and/or dangerous environments. For example, the capabilities investigated will allow multiple groups, including computer and ocean scientists, engineers, educators, students and the general public to observe remote deep sea volcano research taking place live with the highest visual fidelity possible using a satellite link. In doing so, the intent is to begin changing the way that society views real, dynamical ocean systems and the conduct of scientific research in general.

这个项目扩展了ITR计划资助的LOOKING项目的目标。PI要求支持调查和推进网络基础设施在远程环境中的效用，利用两个重要的机会;在东北太平洋的海底火山导向的现场计划同时发生的一个主要的计算和通信展示案例，iGrid，发生在圣地亚哥。PI建议在2005年9月使用联合的Pakk-NSF-UW支持的研究巡航，朝着常规、远程使用高清电视对复杂海底生态系统进行实时调查的方向迈出早期的一步。在这次巡航中，将从JASON遥控潜水器（JASON）向R/V托马斯G号传送活跃海底热液系统的高清电视图像。汤普森，从汤普森到西雅图的UWTV，然后到圣地亚哥的iGrid。科学研究将集中在一系列热液区，这些热液区是沿着全球洋中脊扩张网络已知的最活跃的喷发区之一。它在几十个硫化物结构上容纳了数百个黑烟囱，这些硫化物结构高出海底20至30米。喷口系统支持丰富多样的化学合成生物群落。来自海底的高清电视信号将在汤普森船上记录，现场制作人员将同时记录同步的科学对话，指导研究重点是地震活动，热液输出和海底微生物生产力之间的联系。海底和水面船舶现场馈送的混合和压缩版本将通过Galaxy 10 R卫星传输到UWTV演播室。在UW，来自海上的未压缩图像将与第三个HDTV流混合，其中一组陆地学生，研究人员和REVEL教师通过反向通道音频通信与海上科学家进行互动。三个全带宽视频流和不断更新的上下文材料流将被传输到iGrid会议。由于预期在海洋观测站倡议范围内开发新的研究基础设施，并按照iGrid的传统，这一原型工作的目标是首次展示：1）从深海传送实时、交互式高清晰度图像，用于进行有陆地参与者参与的远程研究的可行性和实用性; 2）在带宽、信号质量和反馈机制上突破极限的实用性和重要性，这些都是为了捕捉复杂的远程环境的动态，以便广泛地分发给陆基观众; 3）后续节目的强大潜力，可实现高清电视流的实时、3D使用，为有线天文台的远程、精确操作开辟了令人兴奋的新研究和外展机会。这是一个尖端的风险项目，可能会产生更广泛的影响：本提案中将研究的许多技术的融合将使来自广泛学科的科学家和教育工作者能够在偏远和/或危险的环境中研究行星到微生物规模的系统动力学。例如，所研究的功能将允许包括计算机和海洋科学家、工程师、教育工作者、学生和公众在内的多个团体使用卫星链路以尽可能高的视觉保真度实时观察正在进行的远程深海火山研究。这样做的目的是开始改变社会看待真实的动态海洋系统和一般科学研究的方式。
