A 340 year record of biogenic sulphur from the Weddell Sea area, Antarctica
Detailed records of methanesulphonic acid (MSA) and non-sea-salt sulpha te (nss So/- ) have been obtained from ice cores drilled on Dolleman Island on the east coast of the Antarctic Peninsula (i0°35 .2' S, 60°55.5' W). Annual average concentrations of MSA arc presented for the period I 65...
