Short summary
BrGDGT distribution in Gonghai Lake is different from surrounding soils, and its derived temperature reflects a mean annual lake water temperature (LWT) that is higher than the mean annual air temperature (AT). The higher mean annual LWT is due to ice formation in winter that prevents thermal exchange between lake water and air.
