GES description |
GES is determined via January to December concentration of total nitrogen (TN) and total phosphorus (TP) in seawater; winter-time concentration of inorganic nitrogen (NO3+NO2–N) (DIN) and phosphates (PO4-P) (DIP) in seawater (HELCOM HOD 39/2012).
GES is achieved if indicator values are below threshold values in the assessment units:
