Chemical, elemental, and isotopic measurements of the upper 8000 years of the archived REnland ice CAP (RECAP) ice core from the Renland ice cap in east-central Greenland; 2022-2024

The overall objective of this research was to develop and interpret detailed records of Arctic lead pollution during the past ~8000 years to better understand the development, history, and impacts of mining and metallurgy from the late Neolithic period to present. The dataset contains high-resolution (30 millimeters [mm] average) measurements of elements, chemical species, and water isotopic ratios in the upper ~520 meters [m] of the archived REnland ice CAP (RECAP) ice core. Included are lead and other parameters such as the rare-earth-element cerium, non-sea-salt calcium, sulfur and sodium used for chronology development and interpretation of the lead record. The core was collected in 2015 from the Renland Ice Cap in east-central Greenland. No archive was available for the upper 99.6 m so the most recent part of the record corresponds to 116 years before 1950 (yb1950) or 1833 current era (CE).
