Increasing iodine deposition in alpine ice

Peer-Reviewed Publication

Proceedings of the National Academy of Sciences

Researchers report that summer iodine concentrations in ice cores from the French Alps tripled between 1950 and 1995, consistent with increased iodine deposition as predicted by chemical transport model simulations; the increased iodine deposition resulted from increased oceanic iodine emissions driven by enhanced ozone levels from anthropogenic nitrogen oxide emissions.
