  1. 1. Accumulation and Composition of Gully Pot Sediments under Varying Anthropogenic Activities

    Författare :Haoyu Wei; Lian Lundy; Maria Viklander; David Butler; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catch basin; Stormwater; Sediment; Urban runoff; Xenobiotics; Gully pot maintenance; Emerging pollutant; VA-teknik; Urban Water Engineering;

    Sammanfattning : Gully pots (GPs) are an integral urban drainage component, contributing to conveying runoff from urban surfaces and reducing the load of solids and associated contaminants entering downstream piped systems and receiving waters. Over time, the silting-up of GPs impairs their hydraulic performance, increasing the risk of GP blockage-induced flood events and reducing solids retention performance. LÄS MER

  4. 3. Black Death - Blue Skies - White Clouds : Water Vapour Uptake of Particles Produced from Traffic Exhaust and their Effect on Climate

    Författare :Cerina Wittbom; MERGE: ModElling the Regional and Global Earth system; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CCN ACTIVATION; Soot; water vapour; climate; SOA; Traffic emission; Fysicumarkivet A:2017:Wittbom;

    Sammanfattning : Aerosol particles are everywhere in the air around us, regardless of whether you are in a busy city or in the serene Arctic. Airborne particles can be produced naturally or anthropogenically, and their properties changes during the time they spend in the atmosphere. LÄS MER

  5. 4. Sea water – shelf sediment interactions: Tracing Neodymium export and water/particle exchange with radiogenic isotopes

    Författare :Per-Olov Persson; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Ocean circulation is a key component for the Earth climate system. Driven by wind and density distribution, governed by temperature and salinity, the ocean currents are redistributing heat from low to high latitudes. LÄS MER

  7. 5. Tracing pathways in the ocean circulation : A temperature and salinity perspective

    Författare :Sara Berglund; Kristofer Döös; Jonas Nycander; Göran Broström; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Lagrangian trajectories; Climate modelling; Atlantic Ocean; Southern Ocean; Ocean circulation; heat; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The ocean circulation plays an essential role in our climate system. It redistributes heat, salt, carbon and other tracers across the globe, making the climate of Earth more moderate. This thesis targets density differences that are driving the ocean circulation. These differences are caused by changes in temperature and salinity. LÄS MER
