Climate changes modulated the history of Arctic iodine during the Last Glacial Cycle

Iodine is important for new particle formation in the atmosphere, but how it varies over long time scales is not well known. Here, the authors present ice core data from the last 127,000 years that show that iodine varied between glacials and interglacials, but also showed abrupt changes in pace wit...

Description
Summary:Iodine is important for new particle formation in the atmosphere, but how it varies over long time scales is not well known. Here, the authors present ice core data from the last 127,000 years that show that iodine varied between glacials and interglacials, but also showed abrupt changes in pace with sea-ice and temperatures.
