Changes in continental and sea-salt atmospheric loadings in central Greenland during the most recent deglaciation: model-based estimates

A simple atmospheric impurity model is used to estimate changes in the atmospheric concentrations of soluble major ions, insoluble particulates and ¹⁰Be during the transition from glacial to Holocene conditions. The model interpolates between the flux and concentration records by explicitly allowing for wet- and dry-deposition processes. It is estimated that the atmosphere over Greenland sampled by snow accumulated during the younger Dryas cold event contained on average four-seven times the isoluble particulates and nearly seven times the soluble calcium derived from continental sources, and about three times the sea salt but only slightly more cosmogenic ¹⁰Be. -from Authors
