Soil organic carbon density in contemporary closed basins and site locations of lake records used in this study. Black dots show the 82 closed-basin lakes with available geophysical-chemical data of lake water. Yellow dots show the 43 closed-basin lakes with available organic geochemical proxies. Green triangles show the 39 closed-basin lakes with available organic carbon data
