These efforts consist of both time series studies as well as survey and process work in various ocean basins. Research  Topics Marine biogeochemistry Carbon and nitrogen cycling Regional oceanography in a global context Dissolved organic matter (DOM) cycling Net community production of DOM Export of DOM in overturning circulation Deep ocean DOM Atmospheric controls on ocean biogeochemistry Opportunities: We look for graduate students annually and also frequently look for undergraduates to work in our lab (contact Dr. Dennis Hansell)
