  1. 1. Surface and Subsurface Flow Connection and Dominating Runoff Mechanism in Hillslope of Tarfala, Northern Sweden.

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Namika Maharjan; [2023]
    Keywords : Advanced Terrestrial Simulator ATS ; hillslope connectivity; tracer test; hydrological modeling; parameter analysis; sub artic regions; hillslope hydrology;

    Abstract : The Sub artic regions are becoming increasingly important due to the effects of climate change. In northern Sweden, thawing of permafrost has led to significant increases in annual minimum flows in several catchments. READ MORE

  3. 2. Temperature dependent preening behaviour in common guillemots Uria aalge

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Saga-Savanna Kynman; [2023]
    Keywords : common guillemot; common murre; seabirds; Stora Karlsö; heatstress; temperature; preening; allopreening;

    Abstract : As global temperature increase, new thermal conditions may challenge the physiological limits of endotherms. Examining the direct effects of extreme temperatures is an important component in understanding how these physiological limits may impact an organism’s behaviour, breeding success and survival.

  4. 3. Possible Bow Shock Current Closure to Earth's High Latitude Ionosphere on Open Field Lines

    University essay from Umeå universitet/Institutionen för fysik

    Author : Gabriella Nordin; [2023]
    Keywords : Space Physics; Bow Shock Current; Field-Aligned Currents; Open Field Lines;

    Abstract : The bow shock is formed due to the abrupt deceleration of the supersonic solar wind in front of the terrestrial magnetic field. The solar wind plasma and the Interplanetary Magnetic Field (IMF) are both compressed across the shock, and according to Ampère's law a current thus flows on the bow shock at all times. READ MORE

  5. 4. Newly inundated forest landscapes - hotspots for mercury in water and benthic fauna

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Kirstine Evald Andersson; [2023]
    Keywords : Wetland restoration; Inundation; Mercury cycling; Beaver impoundments; Aquatic biogeochemis-try;

    Abstract : Mercury (Hg) is a widespread contaminant in high-latitude aquatic ecosystems, where it can undergo microbial transfor-mation into toxic methylmercury (MeHg). Due to its chemical properties, MeHg tends to accumulate in the aquatic food chain and will eventually end up in predatory species at the top of the terrestrial food web. READ MORE

  6. 5. Global Warming Induced by Oceanic Anoxic Event 1a Had a Pronounced Impact on the Early Cretaceous Terrestrial Vegetation of Southern Sweden

    University essay from Uppsala universitet/Paleobiologi

    Author : Marcos Amores; [2022]
    Keywords : palynology; spore-pollen; biostratigraphy; oceanic anoxic event 1a; high-latitude; Early Cretaceous;

    Abstract : The Mesozoic is punctuated by several rapid global warming events that are marked by the worldwide deposition of organic-rich marine sediments. These events, known as oceanic anoxic events (OAEs), are characterised by intervals where the worldwide carbon cycle suffers a disruption due to major palaeoceanographic and climatic shifts, leading to anoxic marine environments and the creation of black shales.
