  1. 1. Turbulence Intensity During Low-Level Jets in the Baltic Sea

    Kandidat-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Thomasson August; [2021]
    Nyckelord :Low-Level Jet; Turbulence intensity; Shear sheltering; LiDAR; Baltic Sea; Low-Level Jet; Turbulensintesitet; Shear sheltering; LiDAR; Östersjön;

    Sammanfattning : Low-level jets (LLJs) are local wind speed maximums in the atmospheric boundary layer. In the Baltic Sea, LLJs are frequently occurring in spring and summer. It is an important phenomena to consider for wind energy parks, and changes in turbulence during the jets can effect the efficiency of said parks. LÄS MER

  2. 2. Massbalans av salt, kväve och fosfor i Dynestadsjön : En pilotstudie innefattande flödesmätningar och modellering

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Isak Spett; [2021]
    Nyckelord :Brackish water; fish death; eutrophication; environmental impact; the Baltic Sea; agriculture; SonTek-IQ Plus; MATLAB; Simulink; Bräckt vatten; fiskdöd; övergödning; miljöpåverkan; Östersjön; lantbruk; SonTek-IQ Plus; MATLAB; Simulink;

    Sammanfattning : Dynestadsjön in Gamleby, Västervik municipality, has a history of collapses due to lack ofoxygen and high levels of salt, nitrogen and phosphorus. The high levels of nutrients havegiven rise to deteriorating living conditions for aquatic organisms. LÄS MER

  3. 3. Microplastics in the Gulf of Bothnia, SwedenA comparison between Österfjärden and Örefjärden.

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Emma Overgaard; [2021]
    Nyckelord :IR; Microplastic; pollution; polymer composition; surface water; visual characterization;

    Sammanfattning : Microplastics are emerging pollutants in the marine environment, including a range of polymers modified by varying quantities of additives and sorbed pollutants, differing in size, colour, and shape. This study focuses on characterization and quantification through visual characterization of microplastics >300 μm in surface water and at 5-meter depth in the Gulf of Bothnia. LÄS MER

  4. 4. Death's reflection in the water : Mortuary ritual, ancestral worship and the cosmological significance of water on the island of Gotland during the Pitted Ware culture

    Kandidat-uppsats, Uppsala universitet/Arkeologi

    Författare :Maja Hed; [2021]
    Nyckelord :ritual; neolithic; grave goods; cosmology; flowing water; divinity; death; Pitted Ware culture; ritual; neolitikum; gravgåvor; kosmologi; rörligt vatten; gudomlighet; död; Gropkeramisk kultur;

    Sammanfattning : The Pitted Ware culture on Gotland presents a multitude of material that allow archeologists to re-construct and visit the socio-economic structure of a middle-neolithic settlement in the Baltic sea. I will be analyzing the archaeological material in accordance to the ocean, and to what we can interpret as ritual and cosmological variables at the site through ritual theory, and with a method of comparative analogy and research.

  5. 5. Mikroplast i tumlare - Metodutveckling i sökandet efter mikroplaster i tarminnehåll från tumlare

    Kandidat-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Thea Eriksson; [2021]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : An ever-growing problem is the increasing amount of microplastics in the sea and how they affect marine organisms. Microplastics are small pieces of plastic that are between 0.1 - 500 micrometres. They are divided into primary and secondary microplastics. LÄS MER
