Short summary
The presented framework advances estimates of particulate organic carbon and nitrogen fluxes in the water column derived from in situ imaging-based particle size distribution data. By accounting for non-sinking particles, depth-dependent degradation, and a dynamic carbon-to-nitrogen ratio that evolves with particle age during settling, it provides a more accurate representation of organic matter export to the deep ocean.
