Data sets

Multi-tracer data of the gas trapping zone of the Lock-In firn and ice core (East Antarctica) K. Fourteau, P. Martinerie, X. Faïn, C. F. Schaller, R. Tuckwell, H. Löwe, L. Arnaud, O. Magand, E. R. Thomas, J. Freitag, R. Mulvaney, M. Schneebeli, and V. Y. Lipenkov

Short summary
Understanding gas trapping in polar ice is essential to study the relationship between greenhouse gases and past climates. New data of bubble closure, used in a simple gas-trapping model, show inconsistency with the final air content in ice. This suggests gas trapping is not fully understood. We also use a combination of high-resolution measurements to investigate the effect of polar snow stratification on gas trapping and find that all strata have similar pores, but that some close in advance.
