  1. 1. Air Pollution from Ships - Emission Measurements and Impact Assessments

    Författare :Hulda Winnes; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

    Sammanfattning : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. LÄS MER

  3. 2. Characterising turbulent ship wakes from an environmental impact perspective

    Författare :Amanda Nylund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; stratification; ship wake; turbulence; methane emission; shipping; energy pollution; environmental impact;

    Sammanfattning : The world’s oceans, especially coastal areas, are intensively trafficked by ships. All these ships exert pressure on the marine environment, through emission to the atmosphere, discharges of pollutants to the water, and physical disturbance through energy input. Of these impacts, energy pollution from shipping has received the least attention. LÄS MER

  4. 3. Remote Measurements of Gas and Particulate Matter Emissions from Individual Ships

    Författare :Jörg Beecken; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pollution; compliance monitoring; shipping; ship emission; particle emissions; identification of polluting ships; emission factors;

    Sammanfattning : Shipping significantly contributes to the world's anthropogenic emissions of sulfur, nitrogen species and particulate matter. These species affect the global radiative forcing as well as local acidification, eutrophication and human health. LÄS MER

  5. 4. Turbulent ship wakes and their spatiotemporal extent

    Författare :Amanda Nylund; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; shipping; ship wake; turbulence; environmental impact;

    Sammanfattning : Shipping activities occur in almost every part of the global oceans and in intensely trafficked shipping lanes there can be up to one ship passage every ten minutes. All these ships impact the marine environment in different ways through pollution or physical disturbance. LÄS MER

  7. 5. Environmentally Sound Management – Its status and role in the sea-land interface regulation of wastes

    Författare :Gabriela Argüello Moncayo; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Environmentally Sound Management ESM ; ship wastes; transboundary movements of wastes; ship source pollution; port reception facilities;

    Sammanfattning : Waste management is essential for ensuring the earth’s resilience and it remains one of the greatest challenges for our and future generations. As societies experience further population growth and economic development, waste management poses both challenges for the protection of the environment and human health. LÄS MER
