(2021-07-05)Blue-green infrastructure (BGI) has become a popular way of combating the effects of climate change, both regarding heat mitigation and runoff from precipitation. This thesis aims to understand the potential of two BGI ... -
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 ... -
Modelling Mosquito Prevalence on a City-Scale in Gothenburg, Sweden. A Methodological Development Study
(2021-06-14)Mosquitoes are one of the most prominent carriers (or vectors) of diseases worldwide, which has an impact on human societies, as up to 1 million people pass away each year from mosquitorelated diseases. Mosquitoes are ... -
Recurring Slope Lineae on the Northern Hemisphere of Mars: an investigation into the new candidate sites
(2021-04-06)Recurring Slope Lineae (RSL), are dark markings found on slopes with a steepness of 25°- 45°. Their width is between 0.5-5 m but they can become hundreds of meters long. They grow incrementally during warm seasons; fade ... -
Spatiotemporal changes in Gothenburg municipality's green space, 1986 to 2019
(2021-04-01)As the world’s population is becoming increasingly more urban the infrastructure expands to accommodate the inhabitants’ needs. In a dense urban environment green space has an important function since it provides vital ... -
Variations in depositional environments of the Paleogene Firkanten Formation across Adventdalen, from Operafjellet to Breinosa
(2021-03-18)The lowermost Paleogene clastic infill of the Central Spitsbergen Tertiary Basin, the coal bearing Firkanten Formation, has been the subject of study for researchers in the past but little focus has been on the northeast ... -
Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden
(2021-03-10)Acid sulphate soils have been referred to as being among the most harmful soils in the world due to their ability to severely decrease the pH of the water, consequently enabling an increased metal load to recipient water ... -
Microstructural evolution of ice under simple shear deformation
(2021-01-11)To investigate microstructure in ice deformed under simple shear conditions experiments were performed with artificial polycrystalline ice and natural ice samples form Vatnajökull glacier in Iceland. A new deformation ... -
Stand Structure in a Heterogeneous Old-growth Norway Spruce (Picea abies (L.) Karst.) Forest in Northern Sweden
(2020-11-19)This study investigate the growth trend in an unmanaged Norway spruce forest in Västerbotten Country, Sweden. The result indicate that relationship between the diameter at breast height (1.3 m) and height follow a ... -
Planetary Boundary Layer Height Variations Over the Tibetan Plateau in Relation to Local Climate Variables and Large-Scale Circulation
(2020-09-09)The lowest layer of the Earth's atmosphere, the planetary boundary layer (PBL), may reach extremely high above the Tibetan Plateau (TP). Moreover, the TP is a hotspot region for climate interactions, exerting far-reaching ... -
Acid sulphate soil in Falkenberg on the west coast of Sweden - The first discovery of active acid sulphate soil outside the Baltic Basin
(2020-09-09)Active AS soil has several negative impacts on the environment due to their ability to severely decrease pH-values and mobilize metals bound in the soil. The negative impacts can especially be seen in aquatic environments ... -
Infiltration, hydrogeology, and heterogeneity - Management of pressure and flow: A case study for the Varberg tunnel project
(2020-07-08)This thesis aims to describe a conceptual model of the sedimentology for Swedish (or nordic) conditions of heterogeneous aquifers but focus is on a case study in Varberg. This to facilitate the identification of main ... -
Mercury and methyl mercury release in soil and water - their relationship with different properties in Skogaryd
(2020-07-08)In Skogaryd research site, water samples were taken and analysed for total mercury (Hgtot) and methylmercury (MeHg) concentration along with the pH, dissolved oxygen (DO) and total organic content (TOC). This to give the ... -
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 ... -
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. ... -
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 ... -
