| Summary: | The main scope of the Marine Strategy Framework Directive is to achieve good
environmental status (GES) of the EU's marine waters by 2020, in order to
protect the marine environment more effectively. The trophic index (TRIX) was
developed by Vollenweider in 1998 for the coastal area of Emilia-Romagna
(northern Adriatic Sea) and was used by the Italian legislation to
characterize the trophic state of coastal waters.

We compared the TRIX index calculated from in situ data (“in situ TRIX”)
with the corresponding index simulated with a coupled physics and
biogeochemical numerical model (“model TRIX”) implemented in the overall
Adriatic Sea. The comparison between in situ and simulated data was carried
out for a data time series on the Emilia-Romagna coastal strip. This study
shows the compatibility of the model with the in situ TRIX and the
importance of the length of the time series in order to get robust index
estimates. The model TRIX is finally calculated for the whole Adriatic Sea,
showing trophic index differences across the Adriatic coastal areas. |
