Data for: Pit lake oxygen and hydrogen isotopic composition in subarctic Sweden: A comparison to the local meteoric water line

This dataset includes the oxygen and hydrogen isotopic composition of rainwater and snow core samples that were used to create a local meteoric water line for an area comprising parts of eastern Norrbotten and Västerbotten in northern Sweden. It also contains oxygen and hydrogen isotopic composition of groundwater and surface water from four pit lakes in the area. The data was used to estimate the residence time of the pit lakes by applying the isotopic mass balance method.
