and Greenland. Sometimes the ice comes directly from north to the northeast corner of Iceland, but all the ice comes from the same source: The East-Greenland current which flows from the Arctic Ocean due south along the east coast of Greenland, passing northwest Iceland. This great cold current transports a lot of ice southwards, both sea ice which is formed in sea water and ice bergs which break off from

explosive eruptions on the edges of the volcano, but large lavaflows are also
known, for example the eruption of the Great Thjórsá Lava (Þjórsárhraun) which
formed by an eruption within the system about 8000 years ago. Eruptions from
the central volcano can cause glacial floods (jökulhlaup) which would be
brought down rivers in the west and/or north of Vatnajökull glacier

in estimating the height of the plume. At this time, the plume reached heights of 8 - 12 km.
During the 2010 Eyjafjallajökull eruption, the weather radar proved to be a very useful tool, but the great distance to the eruption site (160 km) reduced the quality of the data. Therefore, a mobile X-band weather radar was purchased, but while this custom made radar was being assembled and tested, another

% of the freshwater runoff from the continents and is a crucial component of the global climate system. The largest freshwater contribution comes from the great Siberian rivers, but substantial input derives from Alaska and Arctic Canada as well. In addition, the world´s second largest ice mass, the Greenland ice sheet, is located in the Arctic region.
The Arctic HYCOS working group is particularly

predictions can be made.
The solar wind consists mainly of protons and electrons travelling from the Sun at great speeds. It takes these particles about 1-3 days to reach Earth and therefore it is possible to predict major geomagnetic storms. Additionally, particle flux hits the ACE-satellite about one hour before it hits Earth and therefore it is possible to make quite reliable aurora

caused considerable swelling in Svaðbælisá River. The water
contained a great amount of mud, that flowed over fields despite the
levee that was erected to protect the farming land at Thorvaldseyri.
Considerable mud has accumulated in the river channel since the
eruption began, decreasing the depth of the channel. This has caused

will also change the available groundwater resource and stream flow patterns between summer and
winter. Rising sea levels will also affect the development of recreational areas and water abstraction in
coastal zones because of flooding and seawater intrusion into fresh aquifers. Climate change scenarios
pose great challenges to adaptive local and transboundary spatial planning

show that automatic detection especially of events in Greenland maybe is too great a challenge, mainly
due to the low station coverage.

Inevitably, immense eruptions and explosive eruptions are a possibility in the system with imminent threat of ice melting in great magnitude causing a huge jökulhlaup (glacial outburst flood). It is presumed
