Undanfarin aldarfjórðung hafa tíð eldgos í Vatnajökli og breytingar sem af þeim stafa verið fyrirferðamikil í
voferðum JÖRFÍ. Hér er siglt á gúmmíbát í vorferð 2012 um lónið sem myndaðist í kjölfar gossins í maí 2011. –

main bases of Jökulheimar (has four buildings) and
Grímsfjall (three buildings). Research has mainly fo-
cussed on the Vatnajökull glacier and the land under-
neath it, as well as monitoring the growth and retreat
of outlet glaciers in Iceland which is work carried out
by volunteers. Over the last 25 years, volcanic activ-
ity under Vatnajökull and its effect on the glacier has
been a major focus in the spring expeditions. The So-
ciety, in collaboration with the Geoscience Society of
Iceland, publishes the journal Jökull, and has done so
for seven decades. The success of the society in fur-
thering its aims is based on the skills and engagement
of its volunteering members. The collaboration and
companionship built in the various expeditions is one
of the pillars of the Iceland Glaciological Society.
