  1. 1. Multi-Resolution Inference of Bathymetry From Sidescan Sonar

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Zhengjie Ji; [2023]
    Nyckelord :;

    Sammanfattning : How to obtain complete and high-resolution bathymetry is an important research topic in the underwater domain. However, existing methods have certain shortcomings. Multibeam echosounder (MBES) can produce narrow beam range readings of the seafloor, but there is an interval between every two beams (between 10cm to 10m), and the resolution is low. LÄS MER

  3. 2. Modeling for survey priority and extended CATZOC classifications of Swedish territorial waters in the Baltic Sea

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Tilda Karström Hettman; [2022-09-01]
    Nyckelord :;

    Sammanfattning : Hydrographic measurements and producing of sea charts are a vital part of safe navigations for vessels and ships. A request by the SMA in Norrkoping was made to extend CATZOC classifications in Swedish territorial waters by creating a model which could predict how fast the bathymetry would change at different locations.

  4. 3. How fast does the bathymetry change on the Swedish west coast? Modeling how fast the bathymetry change, to know where to prioritize new hydrographic surveys

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Anna Olsson; [2022-06-28]
    Nyckelord :;

    Sammanfattning : The Swedish Maritime Administration is responsible for the passability and availability of vessels on the Swedish coast. They are doing hydrographical surveys to ensure the safety of the maritime transportation corridors on the coast. LÄS MER

  5. 4. Combining Sidescan Sonar and Multibeam Echo Sounder to Improve Bathymetric Resolution per Ping

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Filip Hestell; [2021]
    Nyckelord :;

    Sammanfattning : The master thesis degree project is carried out in the area of robotics, particularly in the area of autonomous underwater vehicles (AUV) and seafloor mapping. The goal of this degree project is to investigate if sidescan sonar data can be used to increase the bathymetric resolution. LÄS MER

  7. 5. Analytic comparison of multibeam echo soundings

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Terje Ole Slinning; [2016]
    Nyckelord :multibeam echo system; geography; GIS; bathymetry and seafloor; hysical geography and ecosystem science; Earth and Environmental Sciences;

    Sammanfattning : This study makes a numeric and visual comparison of two different multibeam echo sounding (MBES) surveys performed at the exact same location, in an effort to establish how reliable and comparable the vertical depth measurements are. The horizontal position uncertainty is not issued in this study. LÄS MER
