The diagram indicates the contribution from different regions and rivers to mean annual inflow of freshwater to the Arctic Ocean (total: 4270 km3 per year). A significant part of the inflow is unmonitored because no hydrological stations are operated in large areas

lake is a wall of ice. On the northern side a tephra wall rises 20 meters
above the water. The ice walls at the southwestern corner of the crater
are melting, i.e. at the site of the vent that was active 4 – 6 June. The
rate of melting is assumed to be about one cuber meter per second.

A scientific
article by Icelandic glaciologists is an important contribution to global studies
and assessments of climate change. The average mass loss of the Icelandic
glaciers per unit area in recent decades is among the highest on Earth.

slowed and it is now around 25 cm per day. The subsidence is in the shape of a bowl and it is greatest

two subglacial lakes, formed due to persistent geothermal activity beneath
Vatnajökull. This activity is apparent on the ice-surface as a circular depression,
known as an ice cauldron. On average, the two neighbouring cauldrons drain
every one to two years, producing floods ranging in maximum discharge from
hundreds to occasionally thousands of cubic metres per second. When
