Designing a species-specific method, based on analysis of eDNA, for detection of lesser weever fish, and testing it at chosen locations along the coastline of Agder, Southern Norway
(Master thesis, 2023)Temperature is largely influencing species dispersion, and when the temperature conditions within an area are changing, species populations often respond by moving to other, more suitable areas. Such behavior has often ... -
Detection and Analysis of Microplastics in Boat Marina and Eelgrass Bed on the Southern Coast of Norway
(Master thesis, 2023)Microplastics are widely distributed around the world and are emerging as one of the most serious environmental problems worldwide. This study aimed to investigate the presence and sources of microplastics by human activities ... -
Do cold-water corals spatially correlate with submarine canyons in the Bay of Biscay? : A GIS study analysing the spatial distribution of cold-water corals along the seascape of the Bay of Biscay
(Master thesis, 2020)The seascape of the Bay of Biscay is a mysterious place. It is located to the west of France and the north of Spainand is often defined as well-differentiated geomorphological unit. The continental margin of the ... -
