Chemical oceanographic, biogeochemical cycles of carbon, nitrogen, phosphorus and silicon in the coastal zones and deep sea environment of Mediterranean, oceanography and ecology of sea ice in the Ross Sea (Antarctica). In particular, such interests are addressed to the analysis of production and regeneration processes, dynamics of plankton communities, uptake of nitrogen-nutrients and nitrogen-fixation, hypoxia/anoxia, mucilage phenomenon, integrated management of coastal zones, pollution due to nutrient and heavy metal discharges, effects of the loads of riverine waters, effects of climate changes on the marine environment, ecology of sympagic communities, development of analytical techniques for chemical oceanography.
