In the past few years, it has been established that remote sensing of wetlands change analysis studies would require careful examination of tidal flooding produced uncertainties in satellite datasets. Tide flagging and filtering mechanisms are required to reduce per-pixel variabilities and errors in change detection. We present a technical note summarizing the potential impact of a lack of tide flagging mechanism in a recent study by Campbell et al. entitled “Global hotspots of salt marsh change and carbon emissions”. Through this note, we highlight the presence of potentially large uncertainties and spatio-temporal variabilities in their wetland change analysis map products propagating to their final carbon emission estimations.
