Drivers of late Holocene ice core chemistry in Dronning Maud Land: the context for the ISOL-ICE project

Data sets

Ice core chemistry, density, conductivity, dust, snow accumulation rate, and stable nitrate isotopic composition of the 120 m ISOL-ICE ice core, Dronning Maud Land, Antarctica V. Holly L. Winton et al. https://doi.org/10.5285/9c972cfb-0ffa-4144-a943-da6eb82431d2

Short summary

In 2018, a new 120 m ice core was drilled in a region located under the Antarctic ozone hole. We present the first results including a 1300-year record of snow accumulation and aerosol chemistry. We investigate the aerosol and moisture source regions and atmospheric processes related to the ice core record and discuss what this means for developing a record of past ultraviolet radiation and ozone depletion using the stable isotopic composition of nitrate measured in the same ice core.
