Marine chemistry is the scientific study of the chemical composition, speciation, reactions, and biogeochemical cycles of substances in the marine environment, including seawater, sediments, and marine aerosols. It addresses the distributions and transformations of major, minor, and trace elements, dissolved gases, nutrients, and organic compounds, and how these are controlled by physical processes (mixing, circulation), biological activity (production, remineralization), and interactions with the atmosphere and lithosphere. Research in marine chemistry underpins understanding of ocean acidification, carbon cycling, redox dynamics, contaminant fate, and the chemical controls on marine ecosystems and climate-relevant processes.
A research team led by Professor Dong-Yeun Koh of the Department of Chemical and Biomolecular Engineering, in collaboration with Professor T. Alan Hatton's group at the Massachusetts Institute of Technology (MIT), developed ...

Permafrost in the Arctic stores large quantities of organic carbon. When frozen ground thaws or coastal sections erode, this carbon can enter the sea, where microorganisms can break it down and convert it into climate-damaging ...

When most people hear the phrase "ocean acidification," they think of coral reefs, shellfish or declining fisheries. Those concerns are real. But while working on our recent research, I found myself asking a different question: ...
