Cover Story: The ocean’s particle fluxes influence marine carbon biogeochemistry. Microplastics are anthropogenic particles, but how their effects compare to those of natural marine particles is only beginning to be addressed. This study explores the impacts of marine particles on dissolved organic matter (DOM) in three scenarios: a particle-free environment, a polystyrene microplastic-enriched system, and a system enriched with inorganic particles (SiO2). DOM derived from a non-axenic strain of marine diatoms was incubated in the dark to monitor differences in microbial reworking under each scenario. Particle-enriched systems showed a higher degree of DOM alteration, indicating that microplastics have a potential role in modifying marine organic matter dynamics on a similar magnitude to that of biogenic inorganic particles.
