Glacier-wide summer surface mass-balance calculation: hydrological balance applied to the Argentière and Mer de Glace drainage basins (Mont Blanc)

摘要: We present the glacier-wide summer surface mass balances determined by a detailed hydrological balance (sSMBhydro) and quantification of uncertainties calculations on Argentiere Mer de Glace-Leschaux drainage basins, located in upper Arve watershed (French Alps), over period 1996–2004. The spatial distribution precipitation within study area was adjusted using situ winter mass-balance measurements. sSMBhydro performance assessed via comparison with based glaciological observations (sSMBglacio). Our results show that has an uncertainty ± 0.67 m w.e. a−1 at 0.66 Glace-Leschaux. Estimates values are good agreement sSMBglacio values. These time series almost same interannual variability. From marked difference between for glacier, we suspect significant role groundwater fluxes balance. This underlines importance taking into account transfers to represent predict hydro-glaciological behaviour catchment.
