Drivers of sea level variability using neural networks
(2023-05-10)Understanding the forcing of regional sea level variability is crucial as many people all over the world live along the coasts and are endangered by extreme sea levels and the global sea level rise. The adding of fresh ... -
Dynamic streams in a pre-alpine catchment
(2021-07-12)This thesis aims to investigate the factors controlling the dynamics of temporary streams, i.e., streams that do not flow throughout the year. Temporary stream hydrology is a relative unexplored scientific field. The ... -
Evaluating a method using pXRF for measuring sulphur along Ostlänken
(2022-09-09)Ostlänken (The Eastern link) is going to be a new main railway in Sweden, between Södertälje and Linköping. The railroad will go through areas where there could be high sulphide concentration in the rocks, and during the ... -
Evaluating DInSAR for measuring seasonal elevation dynamics at the Vissátvuopmi palsa mire complex in Northern Sweden
(2022-09-09)During recent years the palsa mires of Fennoscandia have reported to be undergoing extensive lateral degradation, and in a warming environment the palsa mires of Sweden among others are threatened to thaw completely by ... -
Evaluating Greenery in Urban Typologies - A Study with a Mixed Method Approach in Gothenburg , Sweden
(2021-06-14)A growing number of cities are experiencing challenges with adapting to stresses originating from a changing climate, such as an increase in air temperature and extreme weather events, where urban greenery has shown ... -
Evaluation of the variation in albedo over snow-covered forest in Northern Sweden and Finland
(2022-05-20)The effect of albedo variability induced by meteorological parameters in snow-covered forested areas at local scale is poorly known. Few meteorological stations measure albedo, even though the effect on albedo caused ... -
Explicit consideration of microbes in quantification of gross N rates based on N-tracing model
(2022-01-26)When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates ... -
Exploring Urban Land Cover Changes and the Effect on Nocturnal Air Temperature Dynamics in Helsingborg - A temperature modeling made with TAPM
(2023-10-09)In light of increasing global temperatures, urban areas face growing challenges related to heat stress. Alterations in land cover (LC) within cities contribute to changes in the intra-urban climate, predominantly driven ... -
Extreme precipitation events in the Sichuan Basin and their connection to mesoscale disturbances
(2022-10-04)The Sichuan Basin (SB) is a region with frequent extreme precipitation during summer, principally as a result of its location and topography, with the most extreme events possibly leading to floodings and landslides. A ... -
THE FIRST ACTIVE ACID SULFATE SOIL FOUND OUTSIDE THE BALTIC BASIN, IN VISKA VALLEY WEST COAST OF SWEDEN
(2023-09-15)Acid sulfate (AS) soils are naturally formed but are responsible for environmental problem due to its low pH. Drainage of active AS soils can lead to mobilization of harmful metals and a severe pH drop in nearby aquatic ... -
Fosfors omsättningstid i jord med metoden 33P inkubationsexperiment kombination med isotop utbytes kinetik (IEK) med 33P
(2020-02-05)Fosfor är en begränsad resurs på jorden, i vissa länder går det att finna fosfor naturligt i fosfat rikt berg. För att utnyttja den mängd fosfor som finns på jorden på bästa möjliga vis, är det viktigt att få en djupare ... -
FROM SPACE TO THE SUBSURFACE. Examining Relations Between Vegetation Indices and Local Groundwater Storage.
(2023-11-06)This study aimed to examine the relationship between vegetation indices, NDVI and NDWI, and groundwater levels in the county of Kalmar, utilizing correlation and regression analysis. Further, by examining related geospatial ... -
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 ... -
