“…During spring and 62 summer it moves downslope along the western Adriatic shelf, strongly hits and fills up deep 63 layers of the Jabuka Pit . Its less dense component goes over the 64 Palagruža Sill (Vilibi and Supi , 2005;Wang et el., 2007) and sinks rapidly towards the 65 bottom of the South Adriatic Pit through the mixing and channelling processes in the Bari 66…”

“…Gačić et al (2010) suggested a generalised concept of circulation fluctuations of the central Mediterranean, hypothesizing that the Ionian upper circulation variability is driven by internal dynamics. Namely, formation of dense waters in the Adriatic Sea, the North Adriatic Dense Water (NAdDW, Vilibić and Supić, 2005) and the Adriatic Deep Water (ADW, Vilibić and Orlić, 2001) and its spreading to the deep Ionian Sea influence vorticity balance there, causes a shrinking of the water column along the western perimeter, changes geostrophic balance between the perimeter and the inner Ionian, and induces anticyclonic circulation. The anticyclonic circulation drags a branch of the modified Atlantic water (MAW) towards the Adriatic.…”

Changes in the Adriatic oceanographic properties induced by the Eastern Mediterranean Transient

Abstract. Long-term time series of physical and chemical parameters collected between 1960 and 2010 along the Palagruža Sill transect, Middle Adriatic Sea, have been investigated in terms of average water properties and their variability. Nutrients, especially orthophosphates, reached rather high levels of concentration below the euphotic zone between 1991 and 1998, the highest levels in the investigated period. Simultaneously, the N:P ratio, which is normally higher than 25:1, decreased to values less than 16:1 in the euphotic zone, indicating a switch from typical phosphorus to nitrogen-limited preconditioning for the primary production. Higher-than-usual nutrient levels peaking in the mid1990s, coupled with lower-than-usual temperature, salinity, dissolved oxygen and pH values, are presumably related to the flow of the nutrient richer Western Mediterranean waters to the Adriatic below the euphotic layer. These waters, which keep their footprint in the N:P ratio, enter the Adriatic during the anticyclonic phase of the Bimodal Adriatic-Ionian Oscillation (BiOS), which has been uniquely strengthened by the Eastern Mediterranean Transient occurring in the early 1990s. This hypothesis should be confirmed through targeted research and modelling exercises, as it is highly relevant for the biogeochemistry of the Adriatic Sea.

“…Since the north Adriatic is a shallow sea lying entirely on the continental shelf (average depth 35 m) and is exposed to the winter cold-wind outbreaks, it is a site where shelf dense water occurs, driven by enhanced surface buoyancy loss and cold river runoff. The resulting water mass is named the north Adriatic Dense Water (NAdDW) (Zore-Armanda, 1963;Beg Paklar et al, 2001;Vilibić, 2003;Vilibić et al, 2004;Vilibić and Supić, 2005). This water is cascading towards the deep South Adriatic Pit, through the dynamics which is widely recognized to contribute to the deep water mass changes (Ivanov et al, 2004).…”

Abstract. Unusual weather conditions over the southern Europe and the Mediterranean area in 2003 significantly impacted the oceanographic properties of the Adriatic Sea. To document these changes, both in the atmosphere and the sea, anomalies from the normal climate were calculated. The winter 2003 was extremely cold, whereas the spring/summer period was extremely warm. The air temperature in June was more than 3 standard deviations above the average. On the other hand, precipitation and river runoff were extremely low between February and August. The response of the sea was remarkable, especially in surface salinity during spring and summer, with values at least one standard deviation above the average. Analysis of thermohaline properties in the middle Adriatic showed the importance of two phenomena responsible for the occurrence of exceptionally high salinity: (1) enhanced inflow of saline Levantine Intermediate Water (LIW) in the Adriatic, and (2) extremely low precipitation and river runoff, accompanied with strong evaporation. Two large-scale atmospheric indices: NAOI (North Atlantic Oscillation Index) and MOI (Mediterranean Oscillation Index), although generally correlated to the Adriatic climate, failed to describe anomalies in 2003. The air pressure gradients used for the definition of both indices significantly decreased in 2003 due to the presence of the high pressure areas over most of Europe and the northern Atlantic, and were actually responsible for the observed anomalies above and in the Adriatic.
