Land Use and Land Cover Changes in Europe and the Impact on Near-Surface Wind Speed in Sweden
(2023-08-18)Investigations of Land use and land cover change (LULCC) have recently become of increasing interest. This trend occurs not only based of the importance of biogeochemical processes such as carbon sequestration, but also ... -
Loess in southwestern Sweden. Determining the genesis of the silt-rich layer rödfemman in Svartedalen nature reserve
(2021-10-28)The presence of loess in Sweden is relatively unexplored and has only been found in a few places. Loess acts as a paleoclimatic proxy, which in times of changing climates, is highly relevant. In 1992, Svensson wrote a ... -
Lokalisering av träd för att reducera värmestress. En komparativ studie av Långängen och Nya Kvillebäcken
(2021-11-17)Värmestress har blivit ett växande problem i urbana områden, då städer generellt tenderar att vara varmare än omkringliggande områden. Genom att öka mängden träd i stadsmiljöer kan dess nedkylande förmåga, genom skugga ... -
LÖDÖSEHUS: GEOPHYSICAL METHODS FOR DESCRIBING ARCHAEOLOGY AND NEAR-SURFACE GEOLOGY AT THE SITE OF A MEDIEVAL CASTLE IN LÖDÖSE, SW SWEDEN
(2021-09-21)Near-surface geophysics is a well established method for mapping the geological conditions in the subsurface. The use of geophysics is also a commonly used method in archaeological surveys, although traditionally not as ... -
Magmatic fractionation of trace elements in biotite with emphasis on indium in the Salmi batholith, Russian Karelia
(2020-07-08)Biotite is one of the most common ferromagnesian phases in granitic systems and has a crystal lattice allowing for a range of cation substitutions. The mineral can record whole rock chemistry, mirror processes in the ... -
Major and trace element analysis of common skarn minerals from Långban, Värmland, Sweden
(2022-09-01)The area of Långban, Värmland, is well investigated in terms of the many exotic minerals occurring in the area. In contrast, less focus has been given to the trace element systematics of the commonly occurring skarn-forming ... -
The Making of the Tanum Rock Carvings - A Geological Perspective
(2023-08-18)The Bronze Age rock carvings in Tanum, Bohuslän, are made in glacially polished granite, a hard crystalline rock that is difficult to engrave. This raises the question: How did the Bronze Age carvers make them, and which ... -
Managing Domestic Wells in Sweden. Investigating the role of domestic wells in ensuring a reliable drinking water supply and assessing their vulnerability to climate change
(2023-08-28)Domestic wells provide drinking water for a significant proportion of the population in Sweden, especially in rural areas where public water supplies are not available (Drage, 2022; Hjerne et al., 2021). Domestic wells ... -
The mapping and study of glacial geomorphology near Piteå, Northeastern Sweden
(2023-06-26)Since the beginning of the 20th century numerous mapping projects regarding glacial geomorphology in different regions of Sweden have been published, with methods advancing from in situ field observations to modern remote ... -
Mapping of Quaternary Geomorphology in Southern Dalarna: a LiDAR Study
(2023-01-09)The Quaternary has been a period that has seen a fluctuation in glaciation, in Sweden, for 2.5 million years, with the last glaciation vanishing around 9.6 cal kyr BP. Left behind are glacial landforms that can help us ... -
Mapping state and change of the Scots pine population in Abisko in subarctic Sweden
(2020-07-08)In the face of accelerating climate change, poleward and elevational range expansion have been recorded in many species of the subarctic. In recent decades Scots pine (Pinus Sylvestris) has become more abundant in the ... -
