An integrated analysis of molecular acclimation to high light in the marine diatom Phaeodactylum tricornutum
Nymark, Marianne; Valle, Kristin Collier; Brembu, Tore; Winge, Per; Hancke, Kasper; Andresen, Kjersti; Johnsen, Geir; Bones, Atle M. (Journal article; Peer reviewed, 2009-11-03)Photosynthetic diatoms are exposed to rapid and unpredictable changes in irradiance and spectral quality, and must be able to acclimate their light harvesting systems to varying light conditions. Molecular mechanisms behind ... -
Chemical composition and release rate of waste discharge from an Atlantic salmon farm with an evaluation of IMTA feasibility
Wang, Xinxin; Andresen, Kjersti; Handå, Aleksander; Jensen, Bjørn; Reitan, Kjell Inge; Olsen, Yngvar (Journal article; Peer reviewed, 2013)The carbon (C), nitrogen (N) and phosphorus (P) compositions of salmon feed, fish and faeces were studied at a salmon farm in Badstuvika (63°31’N, 9°9’E) in central Norway. These data were used to estimate the release rates ... -
Modelling the cultivation and bioremediation potential of the kelp Saccharina latissima in close proximity to an exposed salmon farm in Norway
Broch, Ole Jacob; Ellingsen, Ingrid H.; Forbord, Silje; Wang, Xinxin; Volent, Zsolt; Alver, Morten; Handå, Aleksander; Andresen, Kjersti; Slagstad, Dag; Reitan, Kjell Inge; Olsen, Yngvar; Skjermo, Jorunn (Journal article; Peer reviewed, 2013)A 3-dimensional hydrodynamic−ecological model system (SINMOD) was used to estimate the full-scale cultivation potential of the brown alga Saccharina latissima in integrated multi-trophic aquaculture (IMTA) with Atlantic ... -
Molecular and photosynthetic responses to prolonged darkness and subsequent acclimation to re-illumination in the diatom Phaeodactylum tricornutum
Nymark, Marianne; Valle, Kristin Collier; Hancke, Kasper; Winge, Per; Andresen, Kjersti; Johnsen, Geir; Bones, Atle M.; Brembu, Tore (Journal article; Peer reviewed, 2013)Photosynthetic diatoms that live suspended throughout the water column will constantly be swept up and down by vertical mixing. When returned to the photic zone after experiencing longer periods in darkness, mechanisms ... -
System responses to equal doses of photosynthetically usable radiation of blue, green, and red light in the marine diatom Phaeodactylum tricornutum
Valle, Kristin Collier; Nymark, Marianne; Aamot, Inga; Hancke, Kasper; Winge, Per; Andresen, Kjersti; Johnsen, Geir; Brembu, Tore; Bones, Atle M. (Journal article; Peer reviewed, 2014)Due to the selective attenuation of solar light and the absorption properties of seawater and seawater constituents, free-floating photosynthetic organisms have to cope with rapid and unpredictable changes in both intensity ...
