was therefore formed
by ice lifting and deformation induced by subglacial water pressures higher than ice
overburden pressure.
The discharge data and the derived size of the subglacial flood path, as indicated
by the volume of water stored subglacially, indicates a development towards more
efficient subglacial flow over the course of the jökulhlaup. Thus, a discharge in the
