EPICA EDML chemical concentrations and fluxes

Sea salt Na+ and nss Ca2+ data from the EPICA DML (EDML) ice core over the last 150000 yr in 1 m resolution. Data has been calculated from raw data as described in the manuscript. Top 450 m have been averaged from high resolution data after correction for interlaboratory offsets. Negative concentrations after correcting for crustal sodium and sea salt calcium, respectively, have been replaced by zeros. Missing values occur due to sample loss, bad core quality or contamination during sample preparation.
