Differential Drivers of Thermogenic and Bulk Dissolved Organic Matter in the Indian Ocean

Global Biogeochemical Cycles, Volume 40, Issue 5, May 2026.
Abstract The oceanic dissolved organic matter (DOM) pool contains a substantial fraction of recalcitrant carbon, with thermogenic organic compounds representing a chemically distinct, long‐lived component. However, the distribution and transformation of these compounds remain poorly constrained in the Indian Ocean, a key basin of the global overturning
