Abstract

From the North-GRIP deep ice core a continuous record of soluble ions covering the climate history over the last glacial has recently been measured. The measured ions are Li+ , Na+, K+, Mg++, Ca++, F-, Cl- and SO4 -- that are mainly derived from long-range wind transported sea salt and mineral dust aerosols. From this record trends in ion compositions have been derived and compared to the ion compositions measured on the GISP2 and GRIP ice cores in order to quantify changes in source strength and transport efficiency of dust and sea salt aerosols.
