  1. 1. Changes in cetacean presence and behavior in response to reduced marine traffic - the effects of a nationwide lockdown

    University essay from Högskolan i Halmstad

    Author : Lisa Falk Lindberg; Lindqvist Erika; [2022]
    Keywords : ;

    Abstract : Creating noise-pollution and other disturbances, marine traffic poses a great threat to marine mammals all over the world which may demonstrate through short- and long-term changes in behavior and distribution. The Covid-19 lockdown in 2020 provided a setting to study the effects of marine traffic on cetacean presence and interactive behavior. READ MORE

  3. 2. Hydroacoustic Modelling of Podded Propulsion System : Underwater Radiated Noise Prediction Using ANSYS

    University essay from KTH/Teknisk mekanik

    Author : Martin Persson; [2022]
    Keywords : Fluid Mechanics; Computational Aeroacoustics; Frequency Response; Noise and Vibration; Pod; Propulsion System; ANSYS; Reynolds-Averaged Navier-Stokes Equations; Kongsberg Maritime Sweden AB;

    Abstract : Ocean noise pollution is an invisible but growing threat. There are many sources of sound in the ocean but human underwater radiated noise, in particular from shipping is one of the most prominent one. Ocean noise pollution can interfere or sometimes even directly harm marine life. READ MORE

  4. 3. Energy analysis and cost estimation of a potential On-shore Power Supply system in the Port of Gävle

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Juan Gutierrez Saenz; [2019]
    Keywords : On shore Power Supply; Alternative Marine Power; High Voltage Shore Connection; Shore side Power; Ship’s emissions; Marine fuel;

    Abstract : The Port of Gävle is one of the most important harbours in Sweden as far as size and freight capacity is concerned. Marine traffic is increasing greatly, thus environmental pollution as well as noise and vibrations are of major concern in port cities. READ MORE

  5. 4. Looking at Noise: Human Ecological Issues when Assessing the Impact of Seismic Surveys Effects on Oceanic Whales

    University essay from Lunds universitet/Institutionen för kulturgeografi och ekonomisk geografi; Lunds universitet/Humanekologi

    Author : Alice Edwall; [2016]
    Keywords : Airguns; Cetaceans; Anthropocentrism; Anthropogenic noise; Marine noise pollution; Marine sound pollution; Seismic surveys; Uexküll; Umwelt; Whales; Social Sciences;

    Abstract : This thesis introduces different issues regarding the impact of anthropogenic sound pollution on oceanic cetaceans (whales). It involves looking at the problems of anthropocentrism and the notion of Umwelt when trying to assess the well-being of a western culturally important species, and the relationship between that species and the industrialization of the ocean.

  6. 5. Is Cold Ironing Hot Enough? An Actor Focus Perspective of On Shore Power Supply (OPS) at Copenhagen's Harbour

    University essay from Lunds universitet/Internationella miljöinstitutet

    Author : Sara Libera Zanetti; [2013]
    Keywords : cold ironing; on shore power supply; shore side electricity; alternative maritime power; transition; ships emissions; Copenhagen; municipality; Social Sciences; Earth and Environmental Sciences;

    Abstract : This thesis focuses on cold ironing for vessels while berthed at port, with the port of Copenhagen as main case study. With the use of this technique, which is considered by the International Marine Organization (IMO) as a measure to reduce air pollution and noise deriving from shipping activities in ports and coastal areas, vessels are able to shut down their auxiliary engines in order to generate power and replace it with electricity supplied by the shore.
