South Pole ice core total air content Data DOI: https://doi.org/10.15784/601231 Cite as Sowers, T. A. (2019) "South Pole ice core total air content" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/601231. AMD - DIF Record(s) USAP-1443710_1 Abstract The total air content in ice core samples are a fundamental indication of the multitude of processes that impact densification of snow in polar regions. In addition, variations in the elevation of the ice sheet directly control the pressure in the bubble close off region and thereby the total gas content. Attempts to remove the physical factors (temperature, accumulation rate, dust content, seasonality) impacting the total air content could provide a means of assessing variations in the elevation of the South Pole over the last 50,000 years.
