Channel Network Control on Seasonal Lake Area Dynamics in Arctic Deltas حسب Tejedor, Alejandro

"…We find that monthly shrinkage rates have a pronounced structured variability around the channel network with the shrinkage rate systematically decreasing farther away from the channels. This pattern of shrinkage is predominantly attributed to a deeper active layer enhancing near-surface connectivity and storage and greater vegetation density closer to the channels leading to increased evapotranspiration rates. …"
