摘要: Abstract. In this paper we document dense water formation throughout the Adriatic shelf and coastal area in January/February 2012, resulting record-breaking densities observed during after event. The unprecedented generation was preconditioned by a dry warm year which resulted significant reduction of freshwaters, superimposed on long-term basin-wide salinity increase. final event that triggered an extended period cold weather with strong severe winds. Record-breaking potential density anomalies (above 30 kg m−3) were measured at several sites. Accumulated surface net heat losses some regions exceeded 1.5 GJ m−2 250 over 21 days, respectively. Excessiveness, importance shelf-type effects thermohaline circulation deep aquatic systems are discussed.
