Marine dissolved organic matter (DOM) is a major reservoir that links global carbon, nitrogen, and phosphorus. DOM is also important for marine sulfur biogeochemistry as the largest water column reservoir of organic sulfur. Dissolved organic sulfur (DOS) can originate from phytoplankton-derived biomolecules in the surface ocean or from abiotically "sulfurized" organic matter diffusing from sulfidic sediments.

- Frank F Pavia's recent research focuses on the interactions between sulfur biogeochemistry and marine dissolved organic matter (DOM), emphasizing the significance of dissolved organic sulfur (DOS) as a key component in marine ecosystems.
- His study, published in the "Proceedings of the National Academy of Sciences," utilizes novel sulfur isotope analyses to investigate the fluxes of sulfurized porewater, revealing its role as a minor contributor to the overall composition of marine DOM.
- The findings highlight the dual origins of dissolved organic sulfur from both phytoplankton biomolecules and abiotic processes, suggesting a complex interplay within marine sulfur cycles that warrants further investigation.
