Hydrothermal plumes, commonly called black smokers, are formed by hot fluids discharging from seafloor vents on mid-ocean spreading ridges. These fluids entrain the ambient seawater as they rise and are important to understanding the global transport of heat and chemicals in the ocean (which is a factor in climate studies) and to understanding the evolution of marine organisms and microbes. Currently, there are both remote sensing and in-situ methodologies to observe plumes including acoustic imaging, temperature sensors, etc. This proposal combines the data collected by such methods with numerical models in order to develop new predictive models of entrainment and transport.A dynamic data-driven analysis model will be developed and utilized with acoustic imaging instrumentation system in order to provide the immediate feedback necessary to maximize the utility of field experiments.This analysis system will drive predictive models of the entrainment and transport of biological and geological material by the observed hydrothermal plumes, which will facilitate the particulate sampling programs needed to understand larval and chemical transport in the ocean and validate the accuracy of the acoustic imaging method.Broader Impact: The VIP system has the potential to revolutionize the study of hydrothermal plumes by making it possible to gather data efficiently and site measurement instrumentation effectively. This is especially timely given that the NSF RIDGE 2000 program is preparing for an intensive program of studies at the three selected Integrated Study Sites.The VIP system is also applicable to the study of other phenomena such as bubble plumes from methane seeps above gas hydrate deposits, and deep ocean sewage outfall plumes.

热液羽流，通常称为黑烟囱，是由大洋中扩张脊上的海底喷口排出的热流体形成的。这些流体在上升时夹带着周围的海水，对于了解海洋中热量和化学物质的全球传输（这是气候研究的一个因素）以及了解海洋生物和微生物的进化非常重要。目前，有遥感和现场方法来观察羽流，包括声学成像，温度传感器，该建议将通过这些方法收集的数据与数值模型相结合，以便开发新的夹带和输送预测模型。将开发一个驱动分析模型，并与声学成像仪器系统一起使用，以便提供必要的即时反馈，这一分析系统将推动建立关于所观测到的热液羽流对生物和地质物质的夹带和输送的预测模型，这将促进了解海洋中的幼虫和化学物质输送所需的微粒取样方案，并验证声学成像方法的准确性。VIP系统有可能使热液羽流的研究发生革命性变化，因为它可以有效地收集数据和有效地使用现场测量仪器。考虑到NSF RIDGE 2000计划正在为三个选定的综合研究地点的密集研究计划做准备，这是特别及时的。VIP系统也适用于其他现象的研究，如气体水合物沉积物上方甲烷渗出的气泡羽流和深海污水排放羽流。
