Our research aims to improve our understanding of ocean biogoechemistry and to study its relationship to the global carbon cycle.  To do this, we employ a variety of ocean and earth system models, and we use satellite and in situ observations.

Modeling is a critical tool for the study of physical, biogeochemical, and ecological processes in the ocean.  We use a variety of modeling tools in our research, ranging from simple box models to state-of-the-art coupled carbon-climate models.  Such models allow us to simulate important biogeochemical quantities, and to understand what controls their distribution.

Satellite and in situ observations of ocean biogeochemical quantities help us to validate our models and to quantify recent changes in ocean biogeochemistry.  These observations provide information about the amount of anthropogenic carbon dioxide in the ocean, the changing acidity of the ocean, and the activity of ocean phytoplankton in the sea surface, among other things.
