A Global Perspective on Microplastic Concentrations and Characteristics in Sediment and Biota in Marine Coastal Areas
(Master thesis, 2023)Microplastic (MP, < 5 mm) has become an omnipresent environmental pollutant due to inappropriate management since the invention of plastic during the 1800s. MPs are now detected in all environmental matrices, with marine ... -
Analysering av miljø-DNA for kartlegging av marin fiskefauna
(Master thesis, 2016)Marine ecosystems worldwide are currently threatened due to overfishing and other humanimpacts. To monitor marine fish, which represents a main component in present monitoring ofmarine ecosystem health, one is mainly ... -
Analyzing the reliability of citizen science information using Pacific oysters as a model system
(Master thesis, 2023)Det biologiske mangfolds krisen har ført til at mange arter har blitt utryddet de siste 20 årene; En av årsakene til dette er økende nærvær av fremmede arter. Mange av disse artene er uidentifiserte, noe som gjør det ... -
Assessing fish community dynamics in a Norwegian no-take marine reserve compared to a harvested area
(Master thesis, 2022)An ecosystem's ability to respond and maintain key functions during environmental change are largely determined by its biodiversity. As human activities continue to alter the composition of biological communities at all ... -
Assessing impact of fishing on growth of corkwing wrasse (Symphodus melops) and goldsinny wrasse (Ctenolabrus rupestris)
(Master thesis, 2022)Corkwing wrasse (Symphodus melops) and goldsinny wrasse (Ctenolabrus rupestris) are two temperate wrasse (Labridae) species that are targeted by commercial fishery due to their ability to reduce sea-lice infections. The ... -

Bacterial diversity within and outside the premises of a South Norwegian salmon fish farm
(Master thesis, 2021)Norwegian salmon farming is a rapidly expanding sector and the Norwegian Government have a set goal to facilitate a five-fold growth towards 2050. Organic enrichment of the surrounding waters and the sediment below the ... -
Behavioral reactions to H2S in farmed Salmon
(Master thesis, 2023)I resirkulerende akvakulturanlegg kan dannelse av hydrogensulfid (H2S) føre til akutt massedød av laks. Det er begrenset med kunnskap om hvordan fisk reagerer på H2S ved lave konsentrasjoner. Automatisk tolking av adferd ... -
Benthic community distribution pattern in Sandnesfjorden
(Master thesis, 2021)In the marine environment, benthic macrofauna plays a crucial role in carbon and nutrient cycling, decomposition, and as prey items for higher-level consumers. The distribution and composition of macrofauna were studied ... -
Catchability and selectivity in a multispecies wrasse fishery in Western Norway
(Master thesis, 2020)Goldsinny(Ctenolabrus rupestris), corkwing(Symphodus melops)and ballan wrasse(Labrus bergylta) are heavily harvested on the west coast of Norway because of their delousing ability andare supplied to the aquaculture ... -
Copepods dominate the mesozooplankton spring-summer community in a South Norwegian fjord
(Master thesis, 2021)In this study the seasonality of the mesozooplankton community in spring and summer of 2019 at Midtfjordsskjær (MFS), South Norway, was investigated. Zooplankton samples were collected using a fine mesh sized plankton ... -
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 ... -
Døgnvariasjon av fisk i ålegrasenger.
(Master thesis, 2022)Hver dag gjennomføres det som kan kalles verdens største migrasjon av biomasse i havet. Dette er en daglig syklus hvor flere tonn zooplankton beveger seg vertikalt gjennom vanmassene. Dette fenomenet kalles en Dial Vertical ... -
