Growth of scallop spat in a raceway nursery during autumn conditions in western Norwegian coastal waters. P., Davis,., Miller,., Stamnes,.J. Ecological studies on the phytoplankton of Korsfjorden, western Norway. Besides this, virioplankton may act as an internal driving force in spring bloom successions. We have seen that the wind regulated exchange processes between coastal and fjord water, together with light regime, are overall regulating factors. An optical detection system for the study of fine-scale vertical displacement of microalgae in an artificial water column. A new infrared laser equipped with confocal microscopy, including Fluorescence Lifetime Imaging (flim has now being installed in our lab, which implies new opportunities to study basic photosynthetic processes and anatomical changes in microalgal cells as responses to light stress. 35:425-432 Erga,.R., Dybwad,., Frette,., Lotsberg,.K., Aursland,.

Environmental control of phytoplankton distribution and photosynthetic performance at the Jan Mayen Front in the Norwegian Sea. Welcome to Per Markussen's Aerobics, latest News, classes. Pysiological effects of UV-radiation on key species of marine phytoplankton, in collaboration with senior scientist Francisco svein rune markussen Rey, Institute of Marine Research, Bergen. By using a spectral radiative transfer model combined with a parameterization of the inhibition of marine photosynthesis by ultraviolet radiation, it has been found that ozone depletion in polar regions during periods of sufficiently low solar elevations, compromising both open and ice-covered waters, could lead.
