Aspects of in situ angular scattering measurements in contrasting waters
Sandven, Håkon Johan (Doctoral thesis, 2022-01-28)Rapid changes are observed in oceanic and coastal environments around the world due to global temperatures increases, ocean acidification and changing weather patterns - anthropogenic climate change. These changes have ... -
From winter to late summer in the northwestern Barents Sea shelf: Impacts of seasonal progression of sea ice and upper ocean on nutrient and phytoplankton dynamics
Koenig, Zoe Charlotte; Muilwijk, Morven; Sandven, Håkon Johan; Lundesgaard, Øyvind; Assmy, Philipp Kurt Wolf; Lind, Sigrid Gjessing; Assmann, Karen; Chierici, Melissa; Fransson, Agneta; Gerland, Sebastian; Jones, Elizabeth Marie; Renner, Angelika; Granskog, Mats (Journal article; Peer reviewed, 2024)Strong seasonality is a key feature of high-latitude systems like the Barents Sea. While the interannual variability and long-term changes of the Barents Sea are well-documented, the seasonal progression of the physical ... -
Inherent optical properties of dissolved and particulate matter in an Arctic fjord (Storfjorden, Svalbard) in early summer
Petit, Tristan; Hamre, Børge; Sandven, Håkon Johan; Röttgers, Rüdiger; Kowalczuk, Piotr; Zablocka, Monika; Granskog, Mats A. (Journal article; Peer reviewed, 2022)Lysforholdene i havet spiller en nøkkelrolle for marin primærproduksjon og dermed for det hele marine økosystemet. I polområdene er det spesielt stor sesongvariasjon i lysforholdene, og mange ulike prosesser kan påvirke ... -
Neural network approach for correction of multiple scattering errors in the LISST-VSF instrument
Ugulen, Håvard Stavn; Koestner, Daniel Warren; Sandven, Håkon Johan; Hamre, Børge; Kristoffersen, Arne Skodvin; Sætre, Camilla (Journal article; Peer reviewed, 2023)The LISST-VSF is a commercially developed instrument used to measure the volume scattering function (VSF) and attenuation coefficient in natural waters, which are important for remote sensing, environmental monitoring and ...
