Large Scale DOM variability

Large Scale DOM variability
The global ocean holds as much carbon in DOC as there is in the atmosphere. Most of this carbon is stable for several thousands of years, making the ocean an important carbon reservoir in the Earth system. Understanding the dynamics of the oceanic carbon pool is important to decipher its influence on and reaction to a changing climate. We are interested in the mechanisms that lead to the long-term stability of DOM in the ocean. What drives DOC variability on regional, ecosystem and basin scales? Which factors lead to changes in the size of the DOC pool in the global ocean? Which mechanisms act on which spatial and temporal scales to determine DOC variability? We use biogeochemical modeling from box models to 3D ocean models as well as large scale data analysis to address these questions.
