Short summary
We studied how sediment disturbance through bottom trawling or dredging can lead to CO2 release and impair the carbon storage function. By testing a wide range of sediment types across the Hauraki Gulf, we found that the spatial variability of resuspension-induced CO2 release is shaped by local environmental conditions. Our results support the inclusion of seafloor carbon protection in regional fisheries management to sustain the climate stabilizing function of the seafloor.
