2013-5-1 · Stable isotopes of water molecules in hydrology the water cycle and Craig s global meteoric water line (GMWL) relating δ 18 O and δ 2 H are well established with a slope of around 8 and an intercept of around 10. However in many situations the slope is less than 8
2019-7-22 · Local meteoric water lines (LMWLs) represent the site-specific long-term covariation of hydrogen and oxygen stable isotope ratios. LMWLs have practical utility as a hydrologic framework and as benchmarks for evaluating hydroclimatic processes in isotope-enabled climate models. In this manuscript we characterize the global distribution of LMWLs and
The Global Meteoric Water Line (GMWL) describes the global annual average relationship between hydrogen and oxygen isotope (Oxygen-18 and Deuterium) ratios in natural meteoric waters. Wikipedia Hydrogen isotope biogeochemistry
2005-1-12 · described by the Global Meteoric Water Line (GMWL) developed by Craig (1961) and expressed by the equation δH = 8 18O 10 permil. (1) This relation was developed as an average of many local water lines that differ from the GMWL as a result of climatic and geographic factors. Differential fractionation of δ2H and
The Global Meteoric Water Line is an equation defined by the geochemist Harmon Craig 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.
2020-8-31 · isotopecom position. This is known as the Global Meteoric Water Line (GMWL) or evenCraig line (Figure 3). Continental precipitation samples will tend to group close to this line precipitation falling in areas with lower temperature or at higher latitudes will tend to have lower δ2H and δ18O values. Deviations from the meteoric water line
The combined standard deviations associated with the δ 18 O and δ 2 H amount-weighted mean data in 30 of the total 32 stations were used to calculate the local meteoric water line through EIV regression. In two stations Quisquiro and La Serena the calculation of the standard deviation of the weighted mean σ w was performed differently for two reasons.
2001-10-24 · Global Meteoric Water Line (GMWL) as is mentioned in Sect.3.1 (Fig.4.2). Regionally and 44. Observed Isotope Effects for certain periods (such as seasons) Local Meteoric Water Lines (LMWL) may be found depending on the conditions for forming the local water source of each region (see next Section). y = 7.8973x 9.0133
2021-5-19 · The isotopic composition of meteoric water at a given location or region is represented in a scatter plot in which the δ 2 H and δ 18 O distribute along a line named Meteoric Water Line. Worldwide the pattern line is called Global Meteoric Water Line (GMWL) defined by the equation δ 2 H = 8.17 ∙ δ 18 O 10.35 (Rozanski et al. 1993 ).

2001-10-24 · On the average global scale the (18 2) relation turns out to be satisfactorily described by the Global Meteoric Water Line (GMWL) as is mentioned in Sect.3.1 (Fig.4.2). Regionally and for certain periods (such as seasons) Local Meteoric Water Lines (LMWL) may be found depending on the conditions for forming the local water source of each region (see next Section).
The relationship between deuterium and oxygen-18 concentrations in natural meteoric waters from many parts of the world has been determined with a mass spectrometer. The isotopic enrichments relative to ocean water display a linear correlation over the entire range for waters which have not undergone excessive evaporation.
2020-11-3 · The Meteoric Water Line plot is the standard way to portray measurements of stable isotopes in water (18O and 2H). It consists of a scatter plot showing 18O on the X-axis and 2H on the y-axis. The global meteoric water line is typically defined by the following equation Most groundwater and precipitation samples plot close to the line.
A meteoric water line is the statistical linear relationship between hydrogen and oxygen stable isotope ratios measured in precipitation and provides a reference for hydrologic studies. Meteoric water lines may be defined for a site region or globally and reflect the covariance of the water isotope ratios in the sample population across seasons and space. Our analysis leveraged a global

2020-12-6 · The best-fit line was termed the meteoric line. Its equation as found by Craig (1961a) is dD = 8d18O 10. The data in the encircled zone of closed basins is for East African lakes with intensive evaporation. The data in Fig. 9.4 lie on a straight line in spite of the very wide range of values dD of -300 to 50 and d18O of -42 to 6 .
