Oxygen isotopic composition of bulk carbonates in recent sediments from Lake Kuhai (NW China) and implications for hydroclimatic changes in headwater areas of the Yellow River on the northeastern Tibetan Plateau
δ18O values of carbonates are measured for Lake Kuhai on upper reaches of the Yellow River. δ18OBC values co-vary with the Yellow River streamflow in its headwater areas. δ18OBC values can be used as an potential proxy of streamflow of the Yellow River on a long-term base.
