Abstract:
This dataset consists of total air content (TAC) data from 326-416 m from the ice core drilled in 2018-19 at Skytrain Ice Rise (79.7417°S 78.545°W), Antarctica. The samples cover a period of approximately 5000-10000 years before present. Measurements were made on 10 cm long sections of core using a volumetric vacuum-extraction method built in house. No cut-bubble correction has been applied to these data.
