In the absence of light phototrophic algae are lacking the light energy needed for CO<sub>2<\/sub> fixation. For surviving the long time with no light we hypothesize that organic matter uptake may allow the algae to survive\u00a0while waiting for the sun to return. Another process that may become important in the polar night is nitrification.\u00a0With this process\u00a0some bacteria and archaea can fix\u00a0CO<sub>2<\/sub>, not with the energy of light, but with the energy released by oxidizing ammonium or nitrite, which may become more concentrated after upwelling in autumn and reduced uptake by microalgae.<\/p>\n<p>Besides Bernhard Schartm\u00fcller will help us with the fate of light over the polar night and Line Klausen will study the diversity of microalgae over the polar night for her Bachelor thesis.<\/p>\n<p>&nbsp;<\/p>\n<iframe src=\"http:\/\/www.facebook.com\/plugins\/like.php?href=https%3A%2F%2Fsite.uit.no%2Farcticsize%2F2018%2F10%2F01%2Framfjord-seasonal-study-through-the-polar-night-first-cruise%2F&amp;layout=standard&amp;show_faces=true&amp;width=450&amp;action=like&amp;colorscheme=light&amp;height=80\" scrolling=\"no\" frameborder=\"0\" style=\"border:none; overflow:hidden; width:450px; height:80px;\" allowTransparency=\"true\"><\/iframe>","protected":false},"excerpt":{"rendered":"<p>Last week a seasonal study in Ramfjorden started with the first cruise.
