  1. 1. Monitoring marine alien and invasive species. A comparison between the traditional method (eRAS) and DNA-based identification of species.

    Master-uppsats, Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Författare :Josefin Holm; [2023-08-22]
    Nyckelord :;

    Sammanfattning : There is a major concern with the uncontrolled spreading of alien and invasive species, caused by an increase in travelling by boat globally. These are dispersed via ballast water, by fouling on ships and in fishing gear. LÄS MER

  3. 2. Geological 3D Modelling ofthe File Hajdar Quarry, Slite

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Friberg Nils; [2023]

  4. 3. Coral Reef Restoration Enterprises

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Ileana Graf; [2023]
    Nyckelord :Coral reef restoration enterprise CRRE ; Nature-based enterprise NBE ; Coral business; Profitable coral reef restoration; Sustainable business model; Business and Economics;

    Sammanfattning : Coral reefs are essential for providing ecosystem services to humans, including coastal protection, nutrition, and income opportunities for coastal communities. However, coral reefs worldwide have suffered severe damage due to anthropogenic factors, leading to their rapid degradation. LÄS MER

  5. 4. Incorporating local, and placed-based knowledge in resource management: An anthropological study of coral reef entanglements in Costa Rica

    Kandidat-uppsats, Göteborgs universitet/Institutionen för globala studier

    Författare :Hanna Doverhag Utbult; [2022-08-24]
    Nyckelord :Human-environmental relations; Governmentality; Place-based knowledge; Sustainability; TEK; Costa Rica;

The study shows that local actors understand sustainable development as the restoration of relationships to the coral reefs. LÄS MER

  7. 5. Marine Habitat Mapping Using Image Enhancement Techniques & Machine Learning

    Master-uppsats, Jönköping University/JTH, Avdelningen för datateknik och informatik

    Författare :Mudasar Mureed; [2022]
    Nyckelord :Coral Reef; Habitat Mapping; Convolutional Neural Network; Transfer Learning; Fine Tuning; CLAHE;

    Sammanfattning : AbstractThe mapping of habitats is the first step that is done in policies that target theenvironment, as well as in spatial planning and management. The biodiversityplans are always centered around habitats. Therefore, constant monitoring ofthese delicate species in terms of health, changes, and extinction is a must inbiodiversity plans. LÄS MER
