Evaluation of oxygen isotopes in carbonate as an indicator of lake ...
For arid, high-altitude Lake Qinghai, our results suggest that variations in the δ18 O values of carbonate in Lake Qinghai are mainly controlled by the oxygen-isotope ratio of the lake water changing with water salinity. As a secondary effect, increasing water depth leads to cooler bottom and surface water, which may result in more positive δ18 O values of ostracod and bulk carbonate.
Sources and cycling of dissolved organic and inorganic carbon on the ...
