  1. 1. The atmospheric effects of Southern Ocean open-ocean polynyas onto the coastal polynyas from EC-Earth3

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Jakob Gunnarsson; [2023-05-10]
    Nyckelord :;

    Sammanfattning : Polynyas are recurring areas of open water or thin ice within the sea ice pack, which alter the local oceanatmosphere heat and moisture exchange. They are differentiated as coastal (latent heat) or open-ocean (sensible heat) polynya according to their formation process. LÄS MER

  3. 2. Coupling between iron and humic substances in a land-sea transitional zone in the northern Baltic Sea

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anna Osterman; [2023]
    Nyckelord :Iron; Humic substances; Dissolved organic carbon; Baltic Sea; Rivers;

    Sammanfattning : In marine ecosystems around the world, iron (Fe) is a well-studied and important trace element which has been found to stimulate phytoplankton and cyanobacteria growth, as well as limit nitrogen fixation and being essential for Legionella pneumophila which is known as the main cause of Legionnaires’ disease. Fe also contributes to the brownification of freshwater and has recently been documented to increase in concentration in rivers in Sweden. LÄS MER

  4. 3. Optimering av dagvattenlösningar för uppfyllande av miljökvalitetsnormer.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Hjerpe Gabriella; [2023]
    Nyckelord :Stormwater; Environmental quality standards; Pollution load; Decision support; Dagvatten; Miljökvalitetsnormer; Föroreningsbelastning; Beslutsstöd;

    Sammanfattning : Storm water runoff can create major problems in the community if it is not disposed of, or delayed, in the right way. If the disposal of storm water pollution is handled improperly, metals and nutrients can spread to nearby water bodies and contribute to increased unacceptable levels of toxic pollutants. LÄS MER

  5. 4. Navigating Uncertain Waters: A Bayesian Threshold VAR Approach to Understanding the Impact of Commodity Price Shocks on Inflation

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

    Nyckelord :Uncertainty; Bayesian; Commodity Price Pass-Through; Inflation; Threshold VAR;

    Sammanfattning : The Covid-19 pandemic in early 2020 led to unprecedented uncertainty, reducing the predictability of macroeconomic variables. At the same time, commodity price movements as a contributor to national consumer price inflation continue to surface in debates. LÄS MER

  7. 5. Evaluating the effects of climate change on Arctic char : including impacts of brown trout competition

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Ola Carlström; [2023]
    Nyckelord :arctic char; brown trout; climate change; diet; habitat use; temperature;

    Sammanfattning : Climate change is predicted to increase the average global temperature with 1.5 °C between 2030 and 2052. The areas that are most vulnerable for climate change are the arctic regions. Arctic char (Salvelinus alpinus) is a cold-water salmonid species with the most northern distribution of all freshwater fish species. LÄS MER
