Chemical, elemental, and isotopic measurements of the archived HT95 (Hans Tausen 1995) ice core from northern Greenland spanning the past ~5600 years

The specific goal of this project was to develop a more complete and quantitative understanding of natural and anthropogenic drivers of biomass burning over the Common Era. To do so, new high-resolution measurements of a broad range of chemical, elemental, and isotopic species were analyzed on the archived HT95 core using the continuous flow analysis system at the Desert Research Institute in 2023. These new measurements of the Hans Tausen 1995 (HT95) ice core, which was provided by collaborators at the University of Copenhagen, were used along with existing ice-core datasets to underpin atmospheric modeling to understand past emissions of black carbon from biomass burning and anthropogenic activities over the past 250 years (Zhang et al., 2024). The HT95 ice core was collected in 1995 and extends to ~3670 BCE.
