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

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Zhengjie Ji; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tilda Karström Hettman; [2022-09-01]
    Keywords : ;

    Abstract : 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

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Anna Olsson; [2022-06-28]
    Keywords : ;

    Abstract : 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. READ MORE

  5. 4. Våtmarksbatymetri : djupmätning av 10 anlagda våtmarker i Mälardalen

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Gordon Lindau; [2022]
    Keywords : batymetri; djupmätning; portabelt ekolod; kastbart ekolod; våtmark; fosfordamm;

    Abstract : Tio anlagda våtmarker i jordbrukslandskap i Mälardalen har undersökts i syfte att bestämma vattendjup och volym samt för att studera batymetriska metoder som kan vara lämpliga vid djupmätning av fosfordammar och andra grunda våtmarker. De metoder som använts är portabelt, kastbart ekolod som både släpats bakom kajak och kastats med fiskespö från land samt manuell mätning med mätsticka. READ MORE

  6. 5. Estimation of Water Depth from Multispectral Drone Imagery : A suitability assessment of CNN models for bathymetry retrieval in shallow water areas

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Qianyao Shen; [2022]
    Keywords : Bathymetry Retrieval; Multispectral Imagery; Convolutional Neural Network CNN ; Hämtning Av Batymetri; Multispektrala Bilder; Konvolutionellt Neuralt Nätverk CNN ;

    Abstract : Aedes aegypti and Aedes albopictus are the main vector species for dengue disease and zika, two arboviruses that affect a substantial fraction of the global population. These mosquitoes breed in very slow-moving or standing pools of water, so detecting and managing these potential breeding habitats is a crucial step in preventing the spread of these diseases.
