Heitur reitur er landsvæði sem einkennist af mikilli eldvirkni og jarðhita og stendur hátt yfir umhverfið. Ísland er einn af stærstu heitu reitum jarðar og gnæfir 2-4 km yfir venjulega hæð Norður-Atlantshafshryggjarins sem gengur í gegnum landið. Markmið ...

In the aftermath of the financial crisis that invested Iceland starting in September 2008 the town of Hveragerði decided to launch at the end of 2008 a national competition to gather ideas on how a more sustainable future could be designed and implemented ...

This paper presents the first study in the academic literature to explore the various stages in the formation of geothermal ES and their interactions between the biosphere and anthroposphere. This is achieved through the development of the first ES ...

Surtsey, the youngest of the islands of Vestmannaeyjar, is an oceanic volcano created by explosive basaltic eruptions during 1963-1967 off the southern coast of Iceland. The subsurface deposits of the volcano were first sampled by a cored borehole in ...

The electrical signature of volcanoes is affected by several characteristics of rocks: volume and salinity of pore fluid, abundance of conductive minerals, rock temperature and presence of molten crust (magma). Electromagnetic soundings are widely used ...

Environmental life cycle costing (ELCC) is a tool which aggregates five categories of monetary costs across a project's life cycle: investment, operation, maintenance, end-of-life, and externalities. This paper summarises the results from the first two ...

Supercritical fluids have been reported from both rift and subduction-related geothermal systems. They typically form in the vicinity of magmatic intrusions at the roots of geothermal systems upon conductive heating and boiling of the subcritical ...

This article describes how natural geothermal soil temperature gradients in Iceland have been used to study terrestrial ecosystem responses to soil warming. The experimental approach was evaluated at three study sites in southern Iceland; one grassland ...

Geothermal energy utilization contributes to less than 0.5% of the world’s electricity demand and is not well represented in energy policies and environmental studies of energy systems. Research on geothermal potential and environmental impacts shows ...

Oceanic crust is a major transport medium of water into the mantle wedge and the convecting mantle. Yet, the water content of the oceanic crust remains uncertain. Active geothermal systems situated at on-land spreading centers provide a unique opportunity ...
