Regional Isotope Comparison with Mica Lake

Oxygen and hydrogen isotope values for water samples from south Alaska lakes, 2006 and 2007. Gray line is the global meteoric water line [GMWL; δD = 8 δ18O + 10 and gray square is Mica Lake surface water. The slope and distance from the GMWL of the least-squares regression for each region indicates evaporative effects. Note that the Prince William Sound line is parallel with the GMWL.
