Data sets

Physical and morphological parameters of two Antarctic polar sites: Dome C and Lock In. A. Burr, C. Ballot, P. Lhuissier, P. Martinerie, C. L. Martin, and A. Philip https://doi.org/10.18709/PERSCIDO.2018.07.DS225

Short summary

Three-dimensional imaging of the pore network of polar firn from Antarctica was realized in order to relate the morphological evolution of pores with their progressive closure with depth. Evaluating the closed porosity was found to be very dependent on the size of samples and image reconstructions. A connectivity index, which is a parameter less dependent on such issues, was proposed and proved to accurately predict the close-off depths and densities of two polar sites.
