The preservation of methanesulphonic acid in frozen ice-core samples

Abram, Nerilie; Curran, Mark A J; Mulvaney, Robert; Vance, Tessa


Ice-core records of methanesulphonic acid (MSA) provide a potentially powerful tool for producing proxy records of sea ice, a critical but poorly understood component of the Earth's climate system. However, MSA is able to diffuse through solid ice, and here we examine the effect of two different methods of frozen storage on the preservation of MSA in archived ice-core samples. Re-analysis of archived ice sticks confirms that MSA diffuses out of ice cores archived in this manner. Despite MSA...[Show more]
