Surface snow samples containing aeolian dust recovered from 40 sites on first and multi-year McMurdo sea ice using ultra clean methodology in November 2009

55 surface snow samples containing aeolian dust were collected from the McMurdo sea ice using ultra clean methodology along two East-West transects and one North-South transect. Duplicate samples were taken at every second site. Two types of samples were collected, the first in pre-acid washed Teflon bottles (snow surface to 2cm above sea ice surface was samples) and the second in plastic bags where the whole snow profile collected. Wind speed, temperature, snow depth and geographic location were recoded at each site.
