The Antarctic represents the final of the world's nonetheless unexplored continents. considering that 1985, Italy has despatched 9 expeditions to this sector, making it probably the most scientifically lively countries within the Antarctic. Italy has equipped an everlasting base there and has began a scientific selection of information and samples so one can give a contribution to our realizing of this bizarre and intensely attention-grabbing continent. inside this framework, Italy has additionally carried out study in a sub-Antarctic quarter of significant clinical curiosity, the Straits of Magellan. This zone, with its attribute oceanography and biota, represents a transition aspect among the faunal assemblages of temperate and antarctic seas. This atlas at the zooplankton is a vital contribution to the examine of the faunal assemblages of the quarter of the Straits and should confidently be by way of others. The initiative is a part of an unlimited software introduced via the Italian Ministry of Universities and medical and Technological learn to advertise the exploration of Antarctic and sub-Antarctic seas, the purpose of that is to maintain one of many Earth's biggest and such a lot undisturbed traditional laboratories.
