SEDANO Project aim to understand the origin of the glacial depositional systems found offshore the Pacific margin of the Antarctic Peninsula. Four main glacial depositional systems have been identified. Geophysical surveys were carried out during these two projects The cores collected in this area characterise the sediment drifts as composed by fine-grained, poorly-sorted sediments, sourced from turbidity currents generated on the continental slope. To elucidate the role of dispersal and redistribution of sediments by bottom currents, three one-year long bottom current records in the area of the mound 7 were collected as well as nine CTD measurements collected in the same area . It is worthwhile noting the importance of this data set, constituting the first current measurements available in the Pacific margin of the Antarctic Peninsula. The aim of this work threefold: to infer which are the major large scale processes that govern bottom current regime, to understand the Bottom Boundary Layer (BBL) dynamics, and to assess the potential for resuspension induced by the measured currents.

During the I Italian Antarctic expedition (1985/86), 73 rocks have been sampled within the aim of the project "Volcanological research program" in northern Victoria Land. They include different volcanic rocks. The investigated regions are within Mount Melbourne SS 58-60/9 and Mount Murchison SS 58-60/5 USGS sheets.

During the III Italian Antarctic expedition (1987/88), 33 rocks have been sampled within the aim of the project "Geomagnetism" in northern Victoria Land. They include intrusive, subvolcanic, volcanic and metamorphic rocks. The investigated regions are within Mount Melbourne SS 58-60/9 USGS sheet.

The Concordia Research Station provides a unique location for preparatory activities for future human journey to Mars, to explore microbial diversity at subzero temperatures and monitor the dissemination of human-associated microorganisms within the pristine surrounding environment. The present study was performed in the frame of the BacFinder project (European Space Agency, ESA AO-13-Concordia) with the aim to unravel the environmental- and human-associated microbial diversity in the surrounding of the Concordia Station. This is the first intensive and extensive surface snow sampling performed monthly over a two-year period at three distances (10, 500, and 1000 m) from the Concordia Station, and investigated by a high-throughput sequencing approach. Emphasis was laid on the relation between microbial presence and both seasonality and distance from the Base. Data suggested that if present the anthropogenic impact was below the detection limit of the employed DNA sequencing-based techniques. On the other hand, our study corroborated the use of DNA sequencing for revealing microbial presence in remote and hostile environments, with implications for Planetary Protections and for life-detection in astrobiology relevant targets.

During the XII Italian Antarctic expedition (1996/97), 553 rocks have been sampled within the aim of the project "Evolution of East Antarctic craton and paleo-Pacific margin of Gondwana" in northern and southern Victoria Land. They include intrusive, subvolcanic, volcanic and metamorphic rocks. The investigated regions are within Cape Hallett SS 58-60/2, Convoy Range ST 57-60/1, Coulman Island SS 58-60/6, Franklin Island ST 57-60/2*, Freyberg Mountains SS 58-60/1, Mount Joyce SS 55-57/16, Mount Melbourne SS 58-60/9, Mount Murchison SS 58-60/5, Mount Soza SR 57-58/15, Ob' Bay SR 57-58/11, Relief Inlet SS 58-60/13, Sequence Hills SS 55-57/8 and Yule Bay SR 57-58/12 USGS sheets.
