Parrenin, F., F. Rémy, C. Ritz, M.J. Siegert, and J. Jouzel. 2004.
New modelling of the Vostok ice flow line and implication for the glaciological chronology of the Vostok ice core.
Journal of Geophysical Research, Atmospheres, 109, D20102.
DOI: 10.1029/2004JD004561
We have used new spaceborne (elevation) and airborne (ice thickness) data to constrain a 2D1/2 model of snow accumulation and ice flow along the Ridge B-Vostok station ice flow line (East Antarctica). We show that new evaluations of the ice flow line geometry (from the surface elevation), ice thickness (from low-frequency radar data), and basal melting and sliding change significantly the chronology of the Vostok ice core. This new Vostok dating model reconciles orbital and glaciological timescales and is in good agreement with the Dome Fuji glaciological timescale. At the same time, the new model shows significantly older ages than the previous GT4 timescale for the last glacial part, being thus in better agreement with the GRIP and GISP2 chronologies.
STUDY NOTES: Ice age, gas age (computed with the Goujon, JGR, 2003 model), Accumulation, vertical thinning function, temperature and ice origin as produced by the VK-FGT1 ice flow simulation.
