WebLow values during the sedimentation peak in summer indicate nitrogen fixation to be the major N-source. In 2003 this typical annual pattern was visible again. However, as the basic flux of organic matter in this year exceeded the means from 1995 until 2002 by far ( Figure 5 ) an equivalent higher input of accessible nutrients to the mixed layer has to be assumed, … WebWe studied the vertical structure of the phytoplankton community in two toxic cyanobacterial blooms in the offshore Baltic Sea. In 1994, vertically separated potentially toxic, diazotrophic and mixotrophic species (belonging to Cyanophyceae, Dinophyceae and Prymnesiophyceae) dominated. In 1997, picocyanobacteria, mainly in colonies, made up …
