the principalmethods have not changed much over the years, theamount of field work has varied. In the first 15 yearsthe monitoring programme at Storbreen was com-prehensive, often three or more snow density pits
were dug, snow depth was measured at about 600points and ablation was measured on 30 stakes
evenly distri uted on the glacier (Liestøl 1967).Based on experience of the snow pattern, the ob-

of these projects, we have improved
our earthquake, strain and GPS monitoring systems
in collaboration with Icelandic and international
partners, despite considerable cuts being made to
our budget. Hydrological monitoring has improved
significantly and the standard of the monitoring is
now comparable to the weather and earth hazard
monitoring. Hydrological models are in develop-
ment
