Absorption properties of high-latitude Norwegian coastal water: The impact of CDOM and particulate matter
Cirennima, X; Frette, Øyvind; Hamre, Børge; Erga, Svein Rune; Chen, Yi-Chun; Zhao, Lu; Sørensen, Kai; Norli, Marit; Stamnes, Knut; Stamnes, Jakob J. (Peer reviewed; Journal article, 2016-09)We present data from measurements and analyses of the spectral absorption due to colored dissolved organic matter (CDOM), total suspended matter (TSM), phytoplankton, and non-algal particles (NAP) in high-latitude northern ... -
CDOM absorption properties of natural water bodies along extreme environmental gradients
Nima, Ciren; Frette, Øyvind; Hamre, Børge; Stamnes, Jakob J.; Chen, Yi-Chun; Sørensen, Kai; Norli, Marit; Lu, Daren; Xing, Qianguo; Muyimbwa, Dennis; Ssenyonga, Taddeo; Stamnes, Knut; Erga, Svein Rune (Peer reviewed; Journal article, 2019-09-24)We present absorption properties of colored dissolved organic matter (CDOM) sampled in six different water bodies along extreme altitudinal, latitudinal, and trophic state gradients. Three sites are in Norway: the mesotrophic ... -
Chlorophyll a fluorescence lifetime reveals reversible UV-induced photosynthetic activity in the green algae Tetraselmis
Kristoffersen, Arne Skodvin; Hamre, Børge; Frette, Øyvind; Erga, Svein Rune (Peer reviewed; Journal article, 2015)The fluorescence lifetime is a very useful parameter for investigating biological materials on the molecular level as it is mostly independent of the fluorophore concentration. The green alga Tetraselmis blooms in summer, ... -
Testing Fluorescence Lifetime Standards using Two-Photon Excitation and Time-Domain Instrumentation: Fluorescein, Quinine Sulfate and Green Fluorescent Protein
Kristoffersen, Arne Skodvin; Hamre, Børge; Erga, Svein Rune; Frette, Øyvind (Peer reviewed; Journal article, 2018-09)It is essential for everyone working with experimental science to be certain that their instruments produce reliable results, and for fluorescence lifetime experiments, information about fluorescence lifetime standards is ... -
Testing Fluorescence Lifetime Standards using Two-Photon Excitation and Time-Domain Instrumentation: Rhodamine B, Coumarin 6 and Lucifer Yellow
Kristoffersen, Arne Skodvin; Hamre, Børge; Erga, Svein Rune; Frette, Øyvind (Peer reviewed; Journal article, 2014-05-28)Having good information about fluorescence lifetime standards is essential for anyone performing lifetime experiments. Using lifetime standards in fluorescence spectroscopy is often regarded as a straightforward process, ...
