Changes in the nutrient causing eutrophication with water column salinity(2015 and 2016). <br /> Typically phosphorus is the nutrient to be managed in freshwater systems and nitrogen <br /> in marine systems. The indications of phosphorus limitation are all within or adjacent <br /> discharging streams within either the Waquoit Bay or Popponesset Bay Estuaries. It <br /> appears that saline waters of both estuaries are nitrogen limited.(NIP<16). <br /> 41 <br />
