Concentrations of sodium (Na), bromine (Br), calcium (Ca), magnesium (Mg) and chlorine (Cl) measured in the 2015 RECAP ice core by inductive coupled plasma mass spectroscopy (ICPMS) along the 120,000 year-record, as well as the sea-salt sodium (ssNa) calculations are presented. In the 0-8 kyr b2015 section only the Br and Na series are presented, as 100-yr averages.
Note that the Holocene section from 0 to 8200 yr b2015 are 100-yr averages.Note that the below 562 meters the ice has not been dated.
