Abstract: Submarine hydrocarbon seeps are ubiquitous on the continental margins and are important to the global methane inventory. This presentation will discuss a combined effort of observation and modeling to understand dynamical behavior of hydrocarbon bubbles from deep-water natural seeps. Optical and acoustic imaging techniques were used to quantify characteristics of bubbles (size, shape, velocity) and their evolution with onset and dissociation of gas hydrate. This study reveals the detailed physical process of rising seep bubbles released within gas hydrate stability zone. This work is important to understand the role of natural seeps in the oceanic biochemical cycling.
