Minimum nutrient salts concentrations were recorded in
spring, coinciding with reduced salinity, indicating that nitrogen
and phosphorus were regulated by the quick phytoplankton
uptake. Except in winter 2012, RS:DIN ratios tend to be
lower than 1, indicating a potential limitation for diatom
growth, and suggesting a possible advantage for dinoflagellate
growth Calculations of potential
nutrient limitation in the harbour waters suggest no limitation
by PO4.
