(Hið íslenska náttúrufræðifélag, 1997)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 ... -
(European Association of Geochemistry, 2019-07-29)Abiotic formation of n-alkane hydrocarbons has been postulated to occur within Earth's crust. Apparent evidence was primarily based on uncommon carbon and hydrogen isotope distribution patterns that set methane and its higher chain homologues apart ...
-
(Elsevier BV, 2020-12)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 ...
-
(Elsevier BV, 2020-05)This paper reports the results of corrosion study for carbon steel, austenitic stainless steel, as well as titanium and nickel-based alloys which were tested in a simulated superheated geothermal environment (SSGE) in flow-through reactors to investigate ...
-
(Copernicus GmbH, 2019-06-12)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 ...
-
(Paris Sciences et Lettres, Laboratoire de Géologie de l'Ecole Normale Supérieure and University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019-04)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 ...
-
(Springer Nature, 2017-03-08)Background: The article explores the significance of abundant geothermal resources Icelanders enjoy, the comfort of inexpensively heated homes and easily accessible year-round public spaces where young and old can gather irrespective of social standing, ...
-
(Elsevier BV, 2022-07)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 ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2020-03)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 ...
-
(University of Iceland, School of Health Sciences, Faculty of Medicine, 2016-12)Background and aims: Previous studies in geothermal and volcanic areas have shown high risk of certain types of cancers. The aim was to study the association between residence in geothermal areas and the incidence and mortality of cancer in ...
-
(Agricultural University of Iceland, 2016)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 ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Industrial Engineering, Mechanical Engineering and Computer Science, 2021-06)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 ...
-
(MDPI AG, 2020-06-19)The European Union (EU) has made climate change mitigation a high priority though a policy framework called "Clean Energy for all Europeans ". The concept of primary energy for energy resources plays a critical role in how different energy technologies ...
-
(Elsevier BV, 2020)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 ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2017)Molybdenum isotopes are used to quantify changes in Earth’s paleoredox conditions but their application relies upon a simplified model in which rivers dominate the ocean input with minor contributions from hydrothermal fluids. The effect of groundwater ...
-
(Elsevier BV, 2019-06)Developing geothermal power projects may lead to trade-offs, whereby the economic and social benefits of the venture are difficult to compare with its cultural consequences, which include impacts to ES such as aesthetics, spiritual enrichment and ...
-
(Cambridge University Press (CUP), 2020-06-02)Non-surface mass balance is non-negligible for glaciers in Iceland. Several Icelandic glaciers are in the neo-volcanic zone where a combination of geothermal activity, volcanic eruptions and geothermal heat flux much higher than the global average lead ...
-
(University of Iceland, School of Social Sciences, Faculty of Economics, 2018)Enhanced understanding and knowledge concerning a nation’s environmental sustainability performance is necessary to ensure the longterm flourishing capacities of economies and critical to the maintenance of human well-being, particularly through the ...
-
(University of Iceland, School of Engineering and Natural Sciences, Faculty of Earth Sciences, 2019-12-13)An extensive geophysical survey comprising over 400 MT and 515 gravity stations on the Korosi, Paka and Silali volcanoes in the northern Kenya rift was conducted in order to assess the occurrence of geothermal resources in the context of the geophysics ...

Reply (American Geophysical Union, 1994-09-10)The central question discussed by Gudmundsson [this issue] can be succinctly stated: "Is the temperature of the shallowest upper mantle of Iceland at the peridotite solidus" (nominally, 1200°C). The traditional view, as developed by numerous authors ...
