| The sessile hard bottoms zoobenthos community was studied in three northern Adriatic lagoons (Venice, Caorle and Grado-Marano). On the basis of previous researches (1993-1994 in Venice; 1997 in Grado-Marano), these lagoons had been subdivided into ecological sectors. The time consistency of such a subdivision has been assessed. The largest number of species was found in the lagoon of Venice, showing a high heterogeneity of environments and an intense shipping traffic, coupled with aquaculture activities that favoured the arrival of exotic species. A very poor community of obligate oligohaline species was found in Caorle. The natural and stable environment of Grado-Marano lagoon, with its large area of freshwater influence, hosted an intermediate number of... |

| Two lenses of cold water with core temperature 12.5 degrees C were observed in the central Ionian Sea between the thermocline and the salinity maximum due to Levantine Intermediate Water. The estimated salinity in the lenses is 37.8. The relevance of the observation is assured by the high number of expendable probes deployed. The lens diameters are estimated at 30 km. Analogy with a less spectacular feature contained in oceanographic measurements in the following year implies that the lenses rotate clockwise. The cold water lenses originate from the Adriatic Sea with a generation mechanism equivalent to meddy formation at the Iberian peninsula (eddy of Mediterranean water in the Atlantic Ocean). Year to year differences in cold lens generation are expected... |
