A new study, published in Nature Communications, reports for the first time the iodine variability of the Arctic atmosphere for the last 127,000 years. Using two Greenland ice cores, the international team found the highest and lowest iodine levels recorded during interglacial and glacial periods, including the whole last cold period called the Last Glacial Cycle, and has developed a multidisciplinary research strategy to understand the composition of the Arctic atmosphere and what the mechanisms controlled its evolution.

The analysis of the halogens contained in the ice, together with the concentrations of other elements such as calcium or sodium, has revealed how the ocean is the great regulator of iodine in the Arctic atmosphere: the variability of this element is fundamentally controlled by the dynamics of the ice pack and by the biological productivity of the oceans. The concentration of this element can potentially influence climate and this study can help researchers to better constrain the future projections of iodine atmospheric concentrations in the Arctic.

A  new call SIOS to contribute to the state of environmental science in Svalbard (SESS) has been issued. SIOS seeks proposals for new and update chapters that highlight and contribute to the development of the Earth Observing System in and around Svalbard. Call  was opened  on the 1st  of December and will close on 10th January 2022.

SIOS ha lanciato un nuovo bando per contribuire al SESS report. In particolare SIOS è alla ricera di proposte per nuovi capitoli e aggiornamenti dei capitoli precedenti che possano contribuire allo sviluppo del Sistema di osservazione della Terra nelle e intorno alle Svalbard. Il bando è stato aperto il 1 dicembre e si chiuderà il 14 gennaio 2022.
