Astaxanthin as a biomarker for fish feed loading in the marine ecosystem
(Master thesis, 2017)Organic waste released from a fish farm, is one of the main challenges facing aquaculture today, and to increase fish, production it is important to minimize the impact this have on the environment. The aim of this study ... -
Bio-optical diversity on cold water coral habitats
(Master thesis, 2017)This study aimed to elucidate the bio-optical diversity of cold water coral habitats and to further improve the accuracy and efficiency of seafloor mapping with the use of an Underwater Hyperspectral Imager (UHI). Comparison ... -
Combined effects of elevated CO2 and food limitation on early life stages of Clanus finmarchicus
(Master thesis, 2014)The early life stages of Calanus finmarchicus were exposed to two levels of pCO2, 380 ppm (control) and 2080 ppm (elevated CO2) and two different food concentrations, ~ 600 µg C/L (high food concentration) and ~150 µg C/L ... -
Effects of different water treatments on microbial communities when startfeeding European lobster (Homarus gammarus)
(Master thesis, 2014)The challenge with poorly performing larvae and high mortality in replicate tanks is a bottleneck in aquaculture. The main objective of this thesis has been to reveal if differences in performance and survival of the reared ... -
Effects of produced water components on the early life stages of Calanus finmarchicus and Calanus hyperboreus reared at different temperatures
(Master thesis, 2017)Receding sea ice, as a result global warming, increases the marine access to the petroleum resources in the Arctic. Due to the increasing global energy demand, more oil and gas activity is likely to occur. Petroleum ... -
Funksjonell økologi hos pikoplankton - med fokus på bottom-up og top-down effekter
(Master thesis, 2017)Et mesokosme- og et mikrokosmeforsøk ble utført over 10 og 11 dager i Patagonia, Chile. To eksperimentelle variabler ble benyttet; tetthet av kopepoder med to nivåer (lav beiting, LB og høy beiting, HB) og tilsetning av ... -
High Arctic Sea-Ice Algae - The Use of Rapid Light Curves to Assess Photosynthetic Performance of Different Ice-Algal Communities
(Master thesis, 2017)The maximum quantum yield of charge separation in photosystem II (ФPSIImax) was assessed for studying the physiological state of different ice algal communities. By using Rapid Light Curves, relative electron transfer rates ... -
Local variations in species composition on Laminaria hyperborea stipes as response of degree of exposure and impact by aquaculture
(Master thesis, 2018)Laminaria hyperborea kelp forest is a vitally important habitat that provides feeding ground, hiding space and habitat for numerous other species of both fauna and flora. Approximately 80 % of the total Norwegian algae ... -
Macroalgal detritus: Physical variables and impacts on the benthic macrofaunal community
(Master thesis, 2018)Marine primary productivity by micro- and macroalgae in Norway, limited to the photic zone (0 200 m depth), controls the amount of organic carbon (food) available to higher trophic levels, and is the basis for marine ... -
Mapping of a seagrass habitat in Hopavågen, Sør-Trøndelag, with the use of an Autonomous Surface Vehicle combined with optical techniques
(Master thesis, 2017)Mapping and monitoring of marine habitats are important for proper management and decision making. However, shallow coastal habitats (0 5 meters depth) are largely under-sampled in time and space. Knowledge about morphology, ... -
Mapping of demersal fish and benthos by Autonomous Underwater Vehicle equipped with optical and acoustic imagers at 600 meters depth in Trondheimsfjorden
(Master thesis, 2015)The marine environment is largely under-sampled both in time and space. There is a growing need for more automated approaches to provide a better understanding, identification, mapping and monitoring of biogeochemical ... -
Ocean Colour and Phytoplankton Dynamics - An examination of the Forel-Ule scale in a modern context
(Master thesis, 2017)The Forel-Ule scale as a method of determining ocean colour has been in use for over 100 years. Ocean colour is a result of inherent optical properties (IOP) in the water, including phytoplankton biomass, coloured dissolved ... -
Optimising the frequency of clean-up actions in depositional coves in the Lofoten archipelago, Norway to maximize debris removal
(Master thesis, 2018)Marine litter is a global environmental problem which harms a vast amount of species and poses negative economic consequences. Five percent of the marine litter concentrates on the coastlines with an average concentration ... -
Produced water components: uptake kinetics and effects on the metabolism of the Arctic copepod Calanus glacialis
(Master thesis, 2016)The oil exploration and search for new oil production fields is expanding further north and has reached the Arctic. Oil drilling activities release large amounts of produced water (PW) to the marine environment and sub-lethal ... -
Proteininnhold og vekst for Saccharina latissima dyrket ved varierende tilførsel av nitrat og lys
(Master thesis, 2015)Det trengs en økning av matproduksjonen i verden, og en løsning er økning av akvakultur. For at en økning i akvakultur av fôrede arter skal være mulig og bærekraftig trengs det en ny kilde til proteiner som kan supplere ... -
Spectral characteristics of coralline algae: a multi-instrumental approach, with emphasis on underwater hyperspectral imaging
(Master thesis, 2017)Coralline algae constitute a cosmopolitan group of calcifying rhodophytes (red algae) known to form important marine ecosystems. Currently, detailed knowledge of their abundance and distribution is lacking in certain regions ... -
The distribution and diversity of species in the genus Owenia (Polychaeta) in Norwegian waters
(Master thesis, 2014)In this study the diversity and distribution of Owenia species in Norwegian waters are discussed. Owenia fusiformis and the Owenia genus has gone through a turbulent history, with authors describing several new species, ... -
The growth of benthic organisms in a dumping ground for military bombs and munitions
(Master thesis, 2017)Dumping sites for WWII-era bombs and munitions are widespread in the North-East Atlantic. The dumped materiel in such sites pose risks to people and environment through the release of toxic chemicals and accidental detonation. ... -
