Congratulations to Christian Lewis for getting his first paper published in Marine Chemistry! Chemical and isotopic heterogeneity along the marine dissolved organic matter hydrophobicity continuum

Welcome to Alessandra Flaherty who has joined our group as undergraduate student researcher!!

Congratulations to Noreen Garcia for beginning her doctoral work at Scripps!

Congratulations to Professor Brett Walker who has joined U Ottawa as Canada Research Chair!

Our Research Lab focuses on the cycling of marine dissolved organic carbon (DOC), and why it is thousands of 14C years old, despite evidence that most of it is produced in the surface ocean using modern carbon. A very old component of marine DOC is black carbon, produced by combustion of fossil fuels and biomass. We are studying black carbon abundance and 14C, and other components of DOC, and how they cycle through the ocean.
