fjall. In relation to the Bárðarbunga unrest and erup-
tion in 2014–2015, gravity survey was repeated at few
tens of sites on and in close vicinity of Bárðarbunga,
a seismometer was installed during the week at the
centre of Bárðarbunga, to seismic stations were in-
stalled ∼10 km S and SE of Bárðarbunga (to collect
data during the summer), an automatic gas flux gauge
was installed at the rim of an open crevasse on the
south flank of Bárðarbunga and gas flux was mea-
sured at other sites in the vicinity. Samples of the
tephra fallout from the Grímsvötn eruption in 2011
were collected from shallow snow cores drilled at ∼10
sites on Skeiðarárjökull, profiles of winter snow thick-
ness were measured with 500 MHz GeoRadar, and
test profiles with 50 MHz GeoRadar were measured
in Grímsvötn and north of Grímsvötn towards Bárðar-
bunga in hope of tracing some internal layers (vol-
canic tephra) in the ice.
