"Candidatus Subterrananammoxibiaceae," a New Anammox Bacterial Family in Globally Distributed Marine and Terrestrial Subsurfaces
(Journal article; Peer reviewed, 2023)Bacteria specialized in anaerobic ammonium oxidation (anammox) are widespread in many anoxic habitats and form an important functional guild in the global nitrogen cycle by consuming bio-available nitrogen for energy rather ... -
Captive breeding of European freshwater mussels as aconservation tool: A review
(Journal article; Peer reviewed, 2023)1. Freshwater mussels are declining throughout their range. Their importantecological functions along with insufficient levels of natural recruitment haveprompted captive breeding for population augmentation and questions ... -
Capturing big fisheries data: Integrating fishers’ knowledge in a web-based decision support tool
(Journal article; Peer reviewed, 2022-12-12)There is increasing interest in utilizing fishers’ knowledge to better understand the marine environment, given the spatial extent and temporal resolution of fishing vessel operations. Furthermore, fishers’ knowledge is ... -
Capturing the coupled hydro-mechanical processes occurring during CO2 injection – example from In Salah
(Peer reviewed; Journal article, 2014)At In Salah, CO2 is removed from the production stream of several natural gas fields and re-injected into a deep and relatively thin saline formation, in three different locations. The observed deformation on the surface ... -
Carbohydrate metabolism during vertebrate appendage regeneration: What is its role? How is it regulated? A postulation that regenerating vertebrate appendages facilitate glycolytic and pentose phosphate pathways to fuel macromolecule biosynthesis
(Peer reviewed; Journal article, 2014-01)We recently examined gene expression during Xenopus tadpole tail appendage regeneration and found that carbohydrate regulatory genes were dramatically altered during the regeneration process. In this essay, we speculate ... -
Carbon and oxygen fluxes in the Barents and Norwegian Seas : production, air-sea exchange and budget calculations
(Doctoral thesis, 2007-08-17)This thesis focus on the carbon and oxygen fluxes in the Barents and Norwegian Seas and presents four studies where the main topics are variability of biological production, air-sea exchange and budget calculations. The ... -
Carbon Bioavailability in a High Arctic Fjord Influenced by Glacial Meltwater, NE Greenland
(Peer reviewed; Journal article, 2017-06-08)The land-to-ocean flux of organic carbon is increasing in glacierized regions in response to increasing temperatures in the Arctic (Hood et al., 2015). In order to understand the response of the coastal ecosystem metabolism ... -
Carbon to nutrient ratios in marine systems: understanding natural variability Studies of seasonal, inter-annual and regional variability
(Doctoral thesis, 2012-06-29)Ecological stoichiometry deals with the coupling of the carbon (C), nitrogen (N) and phosphorus (P) cycles at the base of the aquatic food webs. Variation in C:N:P stoichiometry is driven by a multitude of factors, and the ... -
Carbonate rock dissolution during CO2 and brine injection – An experimental study applying in-situ imaging by PET and CT
(Master thesis, 2021-03-01)Carbon Capture and Storage (CCS); capture of CO2 from point sources followed by permanent storage in subsurface geological formations; can contribute to mitigating anthropogenic CO2 emissions, and to the ongoing energy ... -
CarboSchools - et utvannet klimaprosjekt eller et forbilde for gode feltstudier i biologi. En casestudie av en biologiklasses erfaringer og utbytte knyttet til CarboSchools prosjektet.
(Master thesis, 2010-12-20)Sammendrag Internasjonale undersøkelser som TIMMS og PISA, samt søkertallene til høyere utdannelser har vist en negativ utvikling for realfagene både kunnskapsmessig og rekrutteringsmessig i løpet av 90-tallet og begynnelsen ... -
Cardiometabolic associations between physical activity, adiposity, and lipoprotein subclasses in prepubertal norwegian children
(Journal article; Peer reviewed, 2021)Lipoprotein subclasses possess crucial cardiometabolic information. Due to strong multicollinearity among variables, little is known about the strength of influence of physical activity (PA) and adiposity upon this ... -

Carnivorous sponges of the Atlantic and Arctic Oceans. Phylogeny, taxonomy, distribution and microbial associations of the Cladorhizidae (Demospongiae, Poecilosclerida)
(Doctoral thesis, 2016-11-29)The sponges (phylum Porifera) are defined by the presence of an aquiferous system in which choanoflagellate cells create a current and filter water flowing through the sponge body. The carnivorous sponges represent the ... -
Carotenoid content in algal epiphytes: A qualitative and quantitative DAD-HPLC analytical study
(Master thesis, 2023-06-01)A qualitative and quantitative study were performed on carotenoid content in algal epiphytes growing on the surface of Laminaria hyperborea. A stability study was also conducted to look at carotenoid degradation under ... -
