Abstract:
The RECAP ice core was drilled on the Renland Ice Cap (71° 18′18′′ N, 26° 43′24′′ W; 2315 m a.s.l.), coastal East Greenland, in 2015. This repository contains Holocene ice core measurements of bromine (Br), iodine (I), sodium (Na), non-sea-salt bromine (nssBr), calcium (Ca), magnesium (Mg), chlorine (Cl) and Bromine enrichment values (Brenr) of the upper ca. 530 meter section of the core, corresponding to the ca. 11,000 years of the Holocene. The primary focus of sodium, bromine and iodine measurements was to investigate the variability of marine and sea ice influence from the northern North Atlantic Ocean to the ice core site. The ice meltwater samples were collected during the Continuous Flow Analysis campaign carried out at the University of Copenhagen in 2015 at a depth resolution of 55 cm. The chemical analyses were carried out by Inductive Coupled Plasma Mass Spectroscopy (ICP-MS).
