Abstract

To examine temporal variability of ¹⁰Be in glacial ice, we sampled snow to a depth of 160 cm at the NEEM (North Greenland Eemian Ice Drilling) drilling site in Greenland. The samples span three years between the summers of 2006 and 2009. At the same time, spatial variability of ¹⁰Be in glacial ice was explored through collection of the upper ∼5 cm of surface snow in Antarctica during part of the Swedish-Japanese traverse from Svea to Syowa station during the austral summer in 2007-2008. The results of the Greenlandic ¹⁰Be snow suggested variable concentrations that apparently do not clearly reflect the seasonal change as indicated by the δ¹⁸O data. The ¹⁰Be concentration variability most likely reflects also effects of aerosol loading and deposition pathways, possibly in combination with post-depositional processes. The Antarctic traverse data expose a negative correlation between ¹⁰Be and δ¹⁸O, while there are weaker but still significant correlations to altitude and distance to the coast (approximated by the distance to the 70th latitude). These relationships indicate that geographical factors, mainly the proximity to the coast, may strongly affect ¹⁰Be concentrations in snow in Queen Maud Land, Antarctica.
