My PhD-studies at the Center of Arctic Gas Hydrates, Environmental, CAGE, focuses on processes in the water column, related to methane gas release at the ocean floor. The question is "how much methane reaches the atmosphere?" There are many mechanisms involved in methane bubbles rising through the water column and dissolved methane. - The need for numerical models is obvious. Expert researchers within for example biogeochemistry and marine geophycisists, will help to improve my models.
