: Continuing discharge of water from Gígjökull due to ice-melt at the
eruption site. Discharge at the old Markarfljót bridge, 18 km from
Gígjökull, is estimated at ~100 m3 s–1, of which ~30 m3 s–1 is baseflow.
Between ~13:00 and 15:45 GMT, a 30-cm rise in stage was recorded at the
bridge; this increase was accompanied by a decease in electrical
conductivity, which is a measure of dissolved solutes
