Temperature dependence of the relationship between pCO2 and dissolved organic carbon in lakes

The relationship between the partial pressure of carbon dioxide (pCO) and dissolved organic carbon (DOC) concentration in Brazilian lakes, encompassing 225 samples across a wide latitudinal range in the tropics, was tested. Unlike the positive relationship reported for lake waters, which was largely...
