The paper overviews research activities carried out as within the 2015 Northern Adriatic Experiment, aiming to explore wintertime processes occurring in the coastal northeastern Adriatic Sea. Field campaigns employing moored ADCPs, a towed undulator, a glider, drifters, a profiling float and ship -borne CTD were conducted in the winter/spring of 2014/2015, accompanied with coupled atmosphere-ocean high- resolution model. The dense water formation have been documented to occur in the area during several consecutive Bora wind outbreaks. Advection of open ocean waters towards the coast, mesoscale variability of a thermohaline front and high-frequency phenomena have been investigated as well.
