Glacial/interglacial variations in methanesulfonate (MSA) in the Siple Dome ice core, West Antarctica
[1] Methanesulfonate (MSA) in the Siple Dome ice core is a record of the deposition of biogenic sulfur to the West Antarctic ice sheet covering the past 100 kyr. Siple Dome MSA levels were low during the last glacial maximum, and increased to higher Holocene levels with a several kyr lag relative to...
