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 has 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 data collected from the Cabled Observatory Vent Imaging System in the Northeast Pacific. The results give new insights to the data and confirm the hypothesis of plumes.

海底热液柱的声学成像可视化

热液羽流是热溶液的持续排放，时间尺度从数月到数年，与海底火山活动有关。声学观测技术的最新发展产生了图像，以支持对此类羽流的科学调查。然而，在长时间序列中理解羽流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来促进羽流的视觉探索和分析，并帮助领域科学家比较由潮汐相互作用模型和包含强制夹带效应的浮力羽流模型预测的羽流的实际行为。地理可视化方法与基于时变特征的技术相结合，以创建羽状流的可视化，这些羽状流应用于从东北太平洋有线天文台通风口成像系统收集的声学成像数据。结果为数据提供了新的见解并证实了羽流的假设。
