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 ... -
An Assessment of Wadis as Suitable for Wastewater Treatment, in a Semi-Arid Region with Limited Data Access – Aleppo, Syria
(2020-07-08)As a consequence of the conflict in Syria, the wastewater treatment plant in southwestern Aleppo has not been fully functioning since 2013, and wastewater is released into the Queiq River without adequate treatment. ... -
Air quality, indoor and outdoor. A study of connections between indoor and outdoor concentrations: NO2, CO2, PM10 and PM2.5
(2020-06-29)Air pollution is a hazard to human health and especially vulnerable are those who live in urban areas. Urban areas are undergoing fast driven urbanization which often results in increased air pollution. Since different ... -
Blå-grön infrastruktur, rumslig fördelning & rekreation. En fallstudie om multifunktionella blå-gröna ytor i Östra Kvillebäcken
(2020-06-29)Blå-grön infrastruktur sammankopplar fragmenterade livsmiljöer, främjar biologisk mångfald och skapar multifunktionella grönytor som möjliggör för bland annat rekreation, dagvattenhantering och klimatreglering. Följande ... -
Distribution of salinity measurements and salinity variations on shelf- and in fjord waters, around Svalbard - throughout the last century
(2020-06-29)Salinity data are an important component of the climate models that seek out to predict the climate variability. This data, of direct measurements, are scattered and needs to be assembled. This thesis set out to gather ... -
Återvätning av dikad torvmark
(2020-06-29)Klimatet förändras med ökad global temperatur och extrema värderevent till följd av mänskliga utsläpp av växthusgaser. Förändring i markanvändningssektorn står för 24% av de totala årliga utsläppen globalt och av de ... -
Cropland and tree cover mapping using Sentinel-2 data in an agroforestry landscape, Burkina Faso
(2020-06-29)Sentinel-2, with high spatial resolution bands and increased number of spectral channels, has provided increased capabilities for vegetation mapping. Cropland masks within heterogeneous areas such as the Sudano-Sahel ... -
Supraglacial lakes monitoring using SAR imagery at Jakobshavn Isbræ, Greenland
(2020-06-26)Supraglacial lakes are a common feature on the Greenland ice sheet. They are mainly found during the melt season which takes place during the summer months when there is a positive net energy flux between the atmosphere ... -
Grímsvötn ash layers, a 3D modeling GPR investigation of the englacial debris within the Vatnajökull ice cap
(2020-06-26)In this report, three-dimensional (3D) modeling is used to facilitate Ground Penetrating Radar (GPR) imagery of the Vatnajökull ice cap, finding and mapping the englacial layers of tephra recorded in the stratigraphy ... -
A case study of a natural habitat for Gymnadenia nigra in Vålådalen, Jämtland, using remote sensing and GIS
(2020-06-26)Since the early 20th century, changes of agricultural practices in Sweden have led to an increased competition from more dominant species in the old forage meadows. As a result, populations of the orchid Gymnadenia nigra ... -
Complex REE zonations in metamorphic garnet reflect accessory mineral reactions
(2020-05-29)A garnet from the Sesia Zone, NW Italy, was selected for Major and Rare Earth Element (REE) mapping, using LA-ICP-MS – a procedure previously not conducted at the Department of Earth Science at University of Gothenburg. ... -
Geochemical haloes surrounding the CSA orebody in Cobar, NSW
(2020-03-05)Geochemical analysis is of great importance to mineral exploration. Ore forming fluids, by definition, change the fresh rock chemistry by introducing and depleting elements. This can be achieved by dilution, element ... -
Greenhoue gas flux over a 50-year post permafrost thaw gradient. Decomposition of soil organic carbon from the Swedish tussock tundra.
(2020-02-11)As the globe is warming the extent of permafrost drastically decreases in the high latitudes. Upon thaw the stored soil organic carbon (SOC) undergoes rapid decomposition and is partly released as trace gases to the ... -
Hydrological catchment analysis from characterisation of organic matter in stream water
(2020-02-05)Organic matter (OM) in aquatic systems is a complex field which have rapidly developed during the last decade due to the introduction of high resolution mass spectrometers. The composition of OM in the aquatic environment ... -
