The climatic circulation of the Gulf of Trieste (northern Adriatic) was studied with a numerical model. In all seasons there is a general inflow into the Gulf of Trieste at its deeper part. In spring and summer, the cyclonic gyre is coupled with an anticyclonic gyre near the closed eastern part of the Gulf. A ‘dome’-like density profile across the Gulf in the inner part of the Gulf above the bottom appears with this circulation. In autumn there is a smaller anticyclonic gyre on its southern side. Near the sea-surface there is a diagonal outflow during winter, driven by the ‘bora’ wind.

Our study aimed to establish potential indicators of fish farming pollution on muddy substrate by means of meiofauna. Harpacticoid copepods and kinorhynchs, whose abundance decreased under the cages, were put forward as indicator taxa. However, harpacticoid copepods were sensitive to fish farm only, while kinorhynchs showed responsiveness to fish farm and to seasonal environmental conditions. The nMDS clearly showed a “cage community” and “control community”, therefore it is a good tool for impact assessment.

Carbon and nitrogen stable isotope ratios of POM were studied in the Gulf of Trieste in a period of mucilage appearance (2004) and without mucilage (2003). Results point to the importance of the biogeochemical properties in spring usually marked with higher riverine discharge. Data contribute to the understanding of mucilage events and help to set-up mechanisms of its prediction as the phenomenon influences marine ecosystem and has negative consequences on tourism, mariculture and fishery. Data indicate the need to adopt the measures for pollution reduction and monitoring of riverine inputs.

Physico-chemical analyses of polluted soils are limited in evaluating complex effects on living environment. Thus, carefully selected bioassays must be used for environmental quality evaluation. We tested four bioassays for evaluation of soil pollution around a metal smelter (Pb, Cd, and Zn): HepG2 and Tetrahymena thermophila comet assay for genotoxic potential, and Vibrio fischeri test and delayed fluorescence of Lemna minor for toxicity evaluation. All but L. minor test proved to be suitable for soil metal pollution evaluation, whereas chemical analysis alone were insufficient as predicted.

Observations of ctenophore species were made in the Gulf of Trieste between 2003 and 2006. We examined native ctenophore species with special attention to representatives of the orders Lobata and Beroida, and we recorded among them two non-native ctenophores: Mnemiopsis leidyi A. Agassiz 1865 and Beroe ovata sensu Mayer, 1912. The validity of the Mediterranean species Beroe ovata is discussed. We determined that among the native species, it is not Beroe ovata but rather Beroe cucumis sensu Mayer, 1912 that occurs in the Mediterranean Sea.
