Continued documentation of the lithology and radioisotope concentrations of the GE1 borehole, Högsbo
(2022-09-05)During 2021, Geogruppen got a mission by Gothenburg Energy to extract a 1000-meter drillcore from the Högbo area in order to test the site for potential geothermal energy production. The site was chosen because of the ... -
A CONTINUED STRUCTURAL DOCUMENTATION OF THE GE1 DRILL CORE
(2022-09-05)Gothenburg Energy, SGU, and Gothenburg University are investigating the possibility for geothermal energy plant in the Gothenburg area. A 1 km drill core were drilled in the Högsbo area and two bachelor thesis were written ... -
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 ... -
A Dendrochronological Investigation of the Effects of Climate on Latewood Growth in Bohuslän, Sweden
(2023-08-16)As climate change becomes a more important issue all over the world, information about past climate is of high relevance to better understand what is changing and different from the past. Tree rings can provide information ... -
Dendrochronological investigations of forest fire, tree ring growth and climate west of Puostijärvi lake, northern Sweden
(2022-07-05)How trees respond to climatic factors such as temperature and precipitation is well documented but can be locally different when other factors play a part in the process. Forest fires have had a large influence in boreal ... -
A Dendrochronological Study of Climate Influence on Earlywood growth in Scots Pine in the Nature Reserve Halle-Vagnaren in Bohuslän, Sweden
(2023-08-18)There has been a great acceleration of global mean surface temperature increase since the 1950s, where changes in different spheres and more frequent weather and climate extremes have been observed. To be able to better ... -
Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data
(2023-08-18)The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with ... -
Determining degree and spatial variation of tetrachloroethylene degradation in groundwater using compound-specific isotope analysis (CSIA) of carbon at the Blekingegatan site in Helsingborg
(2023-12-12)Chlorinated solvents have been used as cleaning detergents in dry cleaners throughout the 20th century which has led to the spread of chlorinated solvents in the environment. Blekingegatan, Helsingborg, is a residential ... -
Distribution of radioactive elements in the RA-granite bedrock northeast of Säve, Sweden A comparison with the Änggårdsbergen area of Central Gothenburg
(2023-08-18)This study aims to compare data regarding the spatial distribution of radioactive elements K, U and Th in two exposed areas of the RA-granite, a 1311 ±8 Ma granitic unit unevenly enriched in these elements. Several ... -
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 ... -
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 ... -
THE EFFECT OF CLIMATE CHANGE ON WEATHER RELATED DISASTERS AND MIGRATION IN ETHIOPIA
(2022-07-11)The ongoing climate change has been the driving force behind an increase of natural hazards around the world, and climate scientists have predicted that the trend will continue to rise. Increased radiative forcing leads ... -
Effekten av klimatförändringar och bete på markkol och kväve i Arktis
(2022-08-30)En av de mest påtagliga konsekvenserna av dagens klimatförändringar är påverkan på Arktisk vegetation. Cirka 50% av jordens markbundna kol återfinns i permafrosten i Arktis. När vegetationen förändras leder detta till ... -
