Glaciers are natural time capsules reflecting the atmospheric contents at the time the snow layer was deposited [1]. Recent work on the Ortles Glacier in the Stelvio National Park of the Eastern Alps (Italy) has recovered ice cores dating as far back as 7000 years. [2] To date, little work has been done on submicron particulates in ice cores since these particles tend to be too small to be detected by the most common analytical techniques. We show here data collected from the 2016 summer and winter shallow snow deposits from the Ortles Glacier. These samples were collected and prepared under careful clean conditions to avoid contamination. [3]
