The Mechanics of Bubble Growth and Rise in Sediments

reportActive / Technical Report | Accession Number: ADA570939 | Open PDF

Abstract:

Our long term goal is a quantitative, mechanistic and predictive understanding of the dynamics of bubbles and bubble populations in marine sediments. We believe that this information can be used to improve and test acoustic backscatter models for gassy sediments and to better understand the ebullitive flux of methane, an important greenhouse gas, to the atmosphere.
