    Description: The Holocene is the most recent geological epoch spanning from about 11700 years ago to the present day. The most important human civilizations appeared during the Holocene. From the Holocene onwards, environmental changes, and the hazards associated with them, became extremely important for their impact on historical events, in some cases blending with humanity’s vicissitudes and influencing the rise and decline of civilizations. This paper summarises the geological and climatic conditions of Northern Europe during the Holocene and tries to determine whether or not they support the hypothesis formulated by Felice Vinci (Vinci, 2003) about the migration of Baltic populations towards the Mediterranean in the Bronze Age at the end of the “climatic optimum” (Houghton et al., 1990; Rohling & De Rijk, 1999). This study presents data on glacio-eustatic changes and on isostatic uplift together with information on probable tsunamis that occurred in the North Atlantic, North Sea, Scandinavia and the Baltic Sea. Moreover, some data on catastrophic events that affected the Mediterranean region are reported, because these catastrophes could have favoured the settlement of “people coming from the sea” that took advantage of the demographic and socio-economic weakening of indigenous populations (Driessen, 2002). The paper aims to provide geological and palaeogeographic constraints to the hypotheses formulated by Felice Vinci on the migration of Scandinavians towards the Mediterranean. The data analysed have been collected from the available scientific literature (see references). The amount of information available for each geological phenomenon is vast and sometimes theories developed from the same data are in conflict. The comparison between the Mediterranean and the Baltic areas (one of which could have been the theatre of the Homeric events) will be useful to find evidence of geological phenomena within the Homeric texts, giving useful indications to better understand where the poems are set or at least to provide interesting discussion points related to Felice Vinci’s hypothesis (Vinci 2003).

    Description: Improving lava flow hazard assessment is one of the most important and challenging fields of volcanology, and has an immediate and practical impact on society. Here, we present a methodology for the quantitative assessment of lava flow hazards based on a combination of field data, numerical simulations and probability analyses. With the extensive data available on historic eruptions of Mt. Etna, going back over 2000 years, it has been possible to construct two hazard maps, one for flank and the other for summit eruptions, allowing a quantitative analysis of the most likely future courses of lava flows. The effective use of hazard maps of Etna may help in minimizing the damage from volcanic eruptions through correct land use in densely urbanized area with a population of almost one million people. Although this study was conducted on Mt. Etna, the approach used is designed to be applicable to other volcanic areas.
    Description: This work was developed within the framework of TecnoLab, the Laboratory for Technological Advance in Volcano Geophysics organized by INGV-CT, DIEES-UNICT, and DMI-UNICT.

    Description: Antarctic surface oceans are well-studied during summer when irradiance levels are high, sea ice is melting and primary productivity is at a maximum. Coincident with this timing, the bacterioplankton respond with significant increases in secondary productivity. Little is known about bacterioplankton in winter when darkness and sea-ice cover inhibit photoautotrophic primary production. We report here an environmental genomic and small subunit ribosomal RNA (SSU rRNA) analysis of winter and summer Antarctic Peninsula coastal seawater bacterioplankton. Intense inter-seasonal differences were reflected through shifts in community composition and functional capacities encoded in winter and summer environmental genomes with significantly higher phylogenetic and functional diversity in winter. In general, inferred metabolisms of summer bacterioplankton were characterized by chemoheterotrophy, photoheterotrophy and aerobic anoxygenic photosynthesis while the winter community included the capacity for bacterial and archaeal chemolithoautotrophy. Chemolithoautotrophic pathways were dominant in winter and were similar to those recently reported in global ‘dark ocean’ mesopelagic waters. If chemolithoautotrophy is widespread in the Southern Ocean in winter, this process may be a previously unaccounted carbon sink and may help account for the unexplained anomalies in surface inorganic nitrogen content.
