Constraining the global marine refractory dissolved organic carbon sources, sinks, and timescales
James is a PhD student majoring in oceanography with Dr. Robert Letscher as his advisor. His research aims to understand the controls of the marine refractory dissolved organic carbon (RDOC) reservoir thru numerical modeling of the global ocean using marine DOC isotopes (14C and 13C) as source, sink, and age tracers. This research is important in determining the sources (autochthonous or allochthonous) of marine RDOC, its lifetimes, and relative contribution to the total DOC inventory in order to recognize the changes in marine RDOC cycling with future climate change.
