Long-term changes in hydrographic conditions in northern Adriatic and its relationship to hydrological and atmospheric processes
International audience A very long data series (1921?2000) of hydrographic parameters (temperature, salinity and density) collected in surface and bottom layers at a station in the coastal zone in the northeastern Adriatic was analyzed. Seasonal and interannual variability of the three parameters is...
