  1. 1. Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Duncan Jones; [2023]
    Keywords : Geography; Geographical Information Systems; GIS; Habitat Modelling; Harbour Porpoise; MaxEnt; Tidal Processes; Conservation; Earth and Environmental Sciences;

    Abstract : Investigating the influence of the tidal regime on harbour porpoise Phocoena phocoena distribution in Mount’s Bay, Cornwall Abstract Unintentional by-catch in fishing gear is a significant cause of mortality of harbour porpoises in UK waters. Understanding the spatial distribution of harbour porpoises at fine scales and how this changes over time is essential when trying to understand where these lethal interactions might occur.

  3. 2. 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

  4. 3. 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.

  5. 4. 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

  6. 5. Marine Geology and Holocene Paleoceanographyof the Southern Quark, Baltic Sea

    University essay from Stockholms universitet/Institutionen för geologiska vetenskaper

    Author : Anton Wagner; [2022]
    Keywords : Bottom currents; Sortable silt; Radiocarbon dating; Baltic Sea stages; Estuarine circulation; Marine sediment cores; Marine geophysical mapping;

    Abstract : The Understen-Märket trench is located in the Southern Quark and is the only deep-water connection between the Baltic Propper and the Gulf of Bothnia. Bathymetric mapping reveals a number of eroded channels and drift deposits exists on the seafloor, indicating that the area is heavily affected by current activity. READ MORE
