MARC recordEvidence of unfrozen liquids and seismic anisotropy at the base of the polar ice sheets / Gérard Wittlinger, Véronique Farra.
| Title: | Evidence of unfrozen liquids and seismic anisotropy at the base of the polar ice sheets / Gérard Wittlinger, Véronique Farra. |
| Author(s): | Wittlinger, Gérard. Farra, Véronique. |
| Date: | 2015. |
| In: | Polar Science. (2015.), Vol. 9(1) (2015) |
| Abstract: | Analyses seismic data from broadband stations located on Antarctic and Greenland ice sheets to determine polar ice seismic velocities. Describes two-layer structure revealed and uses modelling to examine requirement for seismic anisotropy and low vertical S velocity (suggesting unfrozen liquid) in lower layer. |
| Notes: | Polar Science. Vol. 9(1) :66-79 (2015). |
