Comparability of Meteoric Water Lines: Daily, Monthly, Or Annual Data?

The stable isotopes of hydrogen (δ²H) and oxygen (δ¹⁸O) have been widely applied in hydrology. The equation relating δ²H to δ¹⁸O in precipitation, also defined as a meteoric water line, can provide a reference point for interpretation of stable isotopic compositions of a range of water samples in an area. Influenced by many spatial and meteorological factors, the slopes and intercepts of meteoric water lines vary depending on location. Read more.
