Some comments on the flow velocity and thinning of Svenbreen, Dickson Land, Svalbard

In this study a differential GPS survey of flow velocity and surface elevation change of a small glacier Svenbreen, central Svalbard, is presented and discussed. The maximum measured velocity was 3.21 m a-1 at 463 m a.s.l., close the theoretical steady-state equilibrium line altitude. After decades...
