Short summary

This study explores how physicochemical processes, ocean currents, melting sea ice, and freshwater runoff alter biogeochemical cycles on the west Greenland shelf. By analyzing water samples on a high-resolution, large-scale grid, we found that these factors create distinct regional and spatial distribution patterns, significantly impacting biological productivity during late summer.
