Volcano/Ice Interaction Overflight
If weather permits, a 2 hour overflight is planned during the workshop.
It would give participants an opportunity to view from air
tuya and ridge landscape, the island of Surtsey, Myrdalsjokull ice
cap, Skeidararsandur outwash plain and the sites of recent eruptions in
Vatnajokull: Grimsvotn and Gjalp.
The flight is tentatively scheduled for Wednesday morning, August 16th.
However, weather is unpredictable and overflight might take place on
Monday or Tuesday and the affected sessions would then be moved to
Wednesday morning.
The cost of the overflight will be
$220. If weather does not permit an overflight, money will be refunded.
Field Excursion A special
2 1/2 day field trip will be
organized. It will focus on the remains
of subglacial volcanism in South Iceland, including basaltic and rhyolitic
pillow lavas and hyaloclastites and flood deposits and landforms created in
jokulhlaups caused by subglacial eruptions.
Special emphasis will be put on thorough site inspections at a few well
chosen localities, under the guidance of experts. If well attended, it should provide an unique opportunity for
researchers to discuss the workshop topics in the field. Day
1:
The group will leave Reykjavik on August 16.
Visits to the flood plains of Skogasandur and Myrdalssandur. Inspection
of landforms and deposits left by catastrophic floods caused by
eruptions within the Myrdalsjokull ice cap (Katla eruptions), the latest
occurred in 1918. Overnight at Skogar close to the ice capped volcanoes
Myrdalsjokull and Eyjafjallajokull.
Day
2:
Passing along the Laki lava flow of 1783, the route to the north of
Myrdalsjokull is taken into the Torfajokull area, the largest rhyolitic
area in Iceland. Subglacially erupted rhyolitic lava lobes and
hyaloclastite tuffs will be studied at one or two chosen localities. On
the way to the hotel the route passes the volcano Hekla. Overnight at
Laugarvatn.
Day
3:
The day will be used to study basic hyaloclastites and subglacial
landforms in the area to the south of Langjokull glacier. It has several
tuyas, hyaloclastite ridges and shield volcanoes. Subglacially formed
sections at Hlodufell and Tindaskagi will be examined. On the way to
Reykjavik the route passes Thingvellir, the site of the old parliament
Althingi, founded in 930. It is also a rift graben type locality. Good
views to hyaloclastite ridges partly buried in Holocene lavas.
Cost: $440. Includes bus transportation, accommodation (two nights
in double rooms), meals and a tour guide.
