- •
Surface velocity of the Gangotri glacier was analysed using SAR data from 1992 to 2011.
- •
The Gangotri glacier is dynamic throughout its length.
- •
Surface velocity shows a seasonal summer speedup with an inter-annual reduction.
- •
These findings are in striking agreement with proglacial melt–water studies.
- •
Our results imply evolving intra- and inter-annual subglacial hydrodynamic coupling.
