摘要:Abstract(#br)Iceland has the largest area of volcaniclastic sandy desert on Earth or 22,000 km 2 . The sand has been mostly produced by glacio-fluvial processes, leaving behind fine-grained unstable sediments which are later re-distributed by repeated aeolian events. Volcani...

摘要:Abstract(#br)Iceland is an active dust source in the high-latitude cold region. About 50% of the annual dust events in the southern part of Iceland take place at sub-zero temperatures or in winter, when dust may be mixed with snow. We investigated one winter dust event that ...

摘要:Particulate matter mass concentrations and size fractions of PM1, PM2.5, PM4, PM10, and PM15 measured in transversal horizontal profile of two dust storms in southwestern Iceland are presented. Images from a camera network were used to estimate the visibility and spatial ext...

摘要:Abstract(#br)Carbon accumulation in soils is an important method to offset the release of carbon based GHG into the atmosphere. We investigated carbon accumulation during early stages of ecological restoration of a desertified area in Iceland. The study site, a part of a lar...

摘要:Abstract(#br)The parent materials of all Icelandic soils are volcanic in origin, and most of the soils are classified as Andosols. Iceland has the largest area of Andosols in Europe, and may have >5% of all Andosols in the world. A new classification scheme based on the Worl...

摘要:Abstract(#br)Sandy deserts cover > 20 000 km 2 in Iceland, consisting primarily of volcanic materials with basaltic volcanic glass being the main constituent. Wind erosion is severe in the country, causing dust pollution with widespread aeolian redistribution affecting most ...

摘要:Abstract(#br)The Orravatnsrustir palsa site, located north of the Hofsjokull glacier in Central Iceland, has well developed palsas located in a valley-like depression at 710–715 m a.s.l. and stands in remarkable contrast to the surrounding desert-like highland plateau. The p...
