热液羽流是与海底火山活动有关的热溶液持续喷发,时间跨度为数月至数年。声学观测技术的最新发展产生了图像,支持对这种羽流的科学调查。然而,了解羽流在长时间序列中的复杂行为对现有的分析方法提出了挑战。这项工作的动机是使用可视化技术,以促进可视化的探索和分析的羽流,并帮助域科学家比较的实际行为的羽流预测潮汐相互作用模型和浮力羽流模型,包括强制夹带的影响。地理可视化的方法结合随时间变化的功能为基础的技术,以创建可视化的羽流应用到声学成像数据集收集使用有线观测台通风口成像声纳在东北太平洋。这些结果为观测数据提供了新的见解,并证实了羽流假说。
Hydrothermal plumes are ongoing venting of hot solutions, on a time scale of months to years, relating to volcanic activities on the seafloor. Recent developments in acoustical observational techniques have produced images to support the scientific investigation of such plumes. However, understanding the complex behavior of plumes in a long-time series poses a challenge to the existing analysis approaches. The motivation of this work is to use visualization techniques to facilitate the visual exploration and analysis of plumes and to help domain scientists compare the actual behavior of plumes predicted by tidal interaction models and buoyant plume models incorporating forced entrainment effects. Methods of geovisualization are combined with time-varying feature-based techniques to create visualizations of plumes which are applied to an acoustic imaging dataset collected using the Cabled Observatory Vent Imaging Sonar in the Northeast Pacific. The results give new insights to the data and confirm the hypothesis of plumes.
