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 ... -
Density classification of marine seagrass (Zostera marina) for blue carbon estimation using drones and Convolution Neural Networks
Borger, Casper (Master thesis, 2024)Denne masteroppgaven undersøker bruk av konvolusjonelle nevrale nettverk for estimering av blå karbon basert på data samlet fra dronebilder og feltundersøkelser. Studien konsentrerer seg om en sjøgressart kalt ålegras ... -
"Hanging gardens" - comparing fauna communities in kelp farms and wild kelp forests
Bekkby, Trine; Torstensen, Ragnhild Ryther Grimm; Grünfeld, Lars Andreas Holm; Gundersen, Hege; Fredriksen, Stein; Rinde, Eli; Christie, Hartvig C; Walday, Mats Gunnar; Andersen, Guri Sogn; Brkljacic, Marijana Stenrud; Neves, Luiza S.; Hancke, Kasper (Peer reviewed; Journal article, 2023)A growing need for food is causing increased interest for seaweed farming globally. This requires knowledge of the industry’s effects on the marine environment. We therefore aimed to explore the communities hosted by a ... -
How Photosynthesis in Laminaria digitata and Saccharina latissima is Affected by Water Temperature
Aamot, Inga Arnesen (Master thesis, 2011)The aim of this thesis is to give insight into how a short term exposure to higher water temperatures affect photosynthesis in two of the most important species of the Norwegian kelp forest; Laminaria digitata and Saccharina ... -
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 ... -
Photosynthetic responses as a function of light and temperature: Field and laboratory studies on marine microalgae
Hancke, Kasper (Doktoravhandlinger ved NTNU, 1503-8181; 2007:111, Doctoral thesis, 2007)The aim of my thesis is to elucidate the different pathways of light in the marine environment, from underwater irradiance to the absorption of photons in microalgae. The pathway is followed through light harvesting and ... -
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 ...
