A new cooperation between SMHI and the Finnish SYKE has started. This is the first AlgAware with data from samplings with the Finnish ship R/V Aranda. All phytoplankton samples from the Skagerrak, the Kattegat and the Baltic Sea contained low species diversities and all of the cell counts were low Last updated: Apr 23, 2014

AlgAware number 7 is split in two parts because the July cruise is divided into two. This report, part 2, presents phytoplankton analysis from the Skagerrak, the Kattegat and the southwestern part of the Baltic Proper. Phytoplankton analyses have partly been made on board, partly on land, at the Last updated: Apr 23, 2014
