Figure 3. Concentrations of total particulate and dissolved PUAs in the North Adriatic Sea.

Concentrations of total particulate PUAs (fmol cell−1, black circles) were measured using [31] in March a) 2002, and using [24]in March b) 2004, c) 2005 and d) 2006 and concentrations of dissolved PUAs (nM, grey circles) were measured using [26] in March 2006. The diameter of the symbols is proportional to the measurement.
