A basin-wide carbon-related proxy dataset in arid China

Here we present a carbon-related proxy dataset for the Shiyang River Basin in the eastern part of the Hexi Corridor. The dataset collected carbon related indicator data for sediment samples , surface sediment samples and groundwater samples. It includes total nitrogen (TN), total organic carbon (TOC), inorganic carbon (IC), carbon nitrogen ratio (C/N), and organic carbon isotopes(δ13Corg), carbonate carbon Isotopes(δ13Ccarb), oxygen isotopes(δ18O) and other proxy indicator data, as well as profile and groundwater age data. These data will play an important role in studying organic carbon sinks, inorganic carbon sinks, carbon cycling processes, and environmental changes in the closed basin.
