The Global Meteoric Water Line is an equation defined by the geochemist Harmon Craig
[1][2]that states the average relationship between hydrogen and oxygen isotope ratios in natural terrestrial waters, expressed as a worldwide average.
A meteoric water line can also be calculated for a given area, and used as a baseline within that area. Kinetic fractionation will cause the isotope ratios to vary between localities within that area.[3] This relationship is used within the field of isotope hydrology. Craig's original assertion is that the isotopic enrichments, relative to ocean water, display a linear correlation over the entire range for waters which have not undergone excessive evaporation.[4]
