Morphology of Gas Bubbles in Mud: A Microcomputed Tomographic Evaluation

摘要

Free gas in surficial sediments commonly forms gas bubbles that attenuate and dampen acoustic waves, influence slope stability, and contribute to greenhouse gas concentrations. Therefore, determining the mechanisms that control bubble shape, size, growth, and migration is important to acoustic sediment characterization and other disciplines. Previously, gas bubble shape, size, and distribution was quantified using 'low-resolution' (approximately 500 micron) medical computed tomography (CT).
