AMBER OBSERVATIONS: Meta-data-set MSM12_4a

1.) General description of the data set:

A transect of the Baltic Sea was sampled for measuring dissolved organic nitrogen (DON)- vs. dissolved inorganic nitrogen (DIN)- uptake rates. Furthermore the concentration of DOM was performed at the ship using ultra-filtration.
