Nutrient, chlorophyll a concentrations, phytoplankton cell abundances and composition for each transect in the Northern Adriatic Sea.

Mean and range of silicic acid (Si, μM), dissolved inorganic nitrogen (DIN, μM), phosphate concentrations (Pi, μM), particulate organic carbon (POC, μg L−1), molar particulate C:N ratio (mol:mol), chlorophyll a concentrations (μg L−1, based on fluorometric detection after HPLC separation), Skeletonema marinoi (S. marinoi), other diatoms and non-diatom cell abundances (106 cells L−1) and number of stations (N) sampled per transect in March 2002, 2004, 2005 and 2006 in the Northern Adriatic Sea.
