【 摘 要 】

Salinity is a tracer of water and nutrient flows and is employed in studies on coastal environment to establish the coastal or remote origins of pollutants and nutrients. The present article analyses the effects of salinity on the multivariate distribution of the Trophic Index TRIX. The approach taken is based on a multivariate nested model with salinity as an explicative variable. We believe that our results are of use in discerning those areas of the North-West Adriatic Sea influenced by the Po River.
