Abstract:
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.
