Title: Tephra characterization from different natural archives for the study of the impacts of explosive eruptions and past atmospheric circulation paths

Description: The PhD project is focused on the study and characterization of tephra (i.e. unconsolidated clastic material produced by a volcanic eruption) from different geological records, such as ice cores and marine sediments, for the study of the impact of explosive eruptions.

By analyzing and characterizing the tephra and their dispersion it will be possible to obtain important volcanological information such as the age, the volcanic source, the chemical evolution of the magma, the eruptive dynamics and the intensity and magnitude of the eruptions. Tephra also provide time-stratigraphic constraints both for geological and environmental events useful both for paleoclimatic and paleoenvironmental reconstructions. In addition, studying the tephra dispersion will provide important information on the study of past atmospheric circulation paths.

I’ll carry out geochemical analyses both for major and trace elements (EPMA and LA-ICP-MS respectively) and 40Ar/39Ar dating techniques.

Project title: Research and conservation strategies for the paleontological heritage: case studies from Umbria

Abstract: Umbria represents an area of extreme interest for paleontological studies, especially with regard to marine and continental vertebrates of the Pliocene and Pleistocene (last 3 million years approximately). In spite of the great abundance of fossils, also of international scientific importance, the study of some collections is still at a preliminary stage. At the same time, the problem of the conservation of this important heritage has never been addressed, especially considering the multifaceted range of taphonomic contexts from which the fossils come. Through the identification of case studies from heterogeneous stratigraphic and taphonomic contexts, this project aims to provide on the one hand unpublished scientific data fundamental to the knowledge of the Umbrian paleontological heritage, on the other crucial information for its conservation, which can also be exported for other collections in Italy and abroad.

Project title: Assessing large scale ecological responses to climatic change of Central Mediterranean area in the last 2000 years.

Project Description: This project will investigate the ecological dynamics across Central Mediterranean area in the last 2000 years. The semi-enclosed configuration of the Mediterranean Sea makes this a vulnerable region to modern, and also to past climate changes. Archaeological and historic studies and paleoclimatic data make this area a perfect case study to investigate the potential influence of climate on civilisations. The focus will consist in the reconstruction of paleo-floral dynamics. This approach will enable relationships within and between ecosystems, as well as periods of stability and periods of change. The method will mainly consist in the traditional – to reconstruct the vegetational paleo-community - and chemical palynology - to reconstruct past solar irradiance, specifically ultraviolet radiation at the local, habitat scale. Stable isotope analysis of C and O will establish the precipitation regime, the atmospheric CO2 concentration as well as nutrient supply and ecosystem productivity

Titolo: Geochemical-environmental monitoring of soil gases and gases dissolved in groundwater

The research, in collaboration with Thearen srl, consists in testing a network of mobile sensors for monitoring the concentration and fluxes of gases from soil ad natural waters. The analysis will be done on Greenhouse gases such as carbon dioxide and methane and also on indirect greenhouse gases with high global warming potential including volatile organic compounds (VOC). We will use low energy consumption sensors for the concentration of CO2 and CH4 and also the new accumulation chamber under developement in Thearen srl for the fluxes of CO2, CH4 and VOC. The research has three main phases of which the first is a. choice and testing of sensors and the accumulation chambers, b. monitoring network design, geostatistical and machine learning software developement and c. to experiment the network in different geological-environmental contexts. The geological-environmental contexts could be anthropogenic contexts like potentially contaminated sites, landfills and clean-up areas or natural contexts like large-degassing processes areas like geothermal, volcanic and seismic regions.

Titolo: Mapping the thermophysical properties of Appennines rocks: implications for the geothermal potential

Descrizione: Nonostante l'esistenza di un elevato numero di misure del flusso di calore nel mondo, l'andamento della temperatura all'interno della Terra è molto incerto. Con questo progetto mi propongo di effettuare un'ampia raccolta di campioni sulla quale condurre misure di proprietà termofisiche quali conducibilità termica, diffusività termica, capacità termica specifica, densità, porosità e composizione mineralogica, con lo scopo di mappare la conducibilità termica dei campioni analizzati e ricavare delle relazioni teoriche tra le proprietà, che possano essere applicate anche per rocce presenti in altri parti del mondo. Tutto ciò potrebbe avere implicazioni sulla stima del potenziale geotermico delle aree di studio.

Titolo: TERRA - geodiversiTy and biodivERsity in uRban Areas

Descrizione: The current Climate Emergency calls for political actions and research aimed at building a more sustainable future for all. As stated by the World Urbanization Prospects of 2018 (ONU), within the 2050 the urban areas will host more than the 70% of population. Thus, the need for more sustainable cities is a really urgent issue too. Hence, In my PhD project I would like to define a new quantitative and scale-independent model of geomorphodiversity (GM), as a starting point for the life support on Earth and as and index of the geomorphological variety in urban areas. The analysis of the correlation between the GM index and the biodiversity index will create a potential new indicator for the safeguard of green spaces in the city. This indicator will be then tested in three different urban context. A final step will foreseen a larger map analysis in Italy through the use of the geomorphodiversity index. All the PhD project will be carried out with the collaboration of many researchers and Institute: the CNR IRPI of Perugia, the Department of Physics and Geology and the Department of Agricultural, Food and Environmental Sciences of Unipg , the University of Lousanne and the Sapienza University in Rome.

Progetto di studio per il PhD:
Titolo: Multispectral data analysis for detection of environmental effects induced by large earthquakes

Descrizione: Large earthquakes produce important effects on the natural and anthropic environment which can last for several years or decades. These earthquakes are able to perturb the environment in terms of important ground deformation, hydrologic crises and dangerous landslides. The monitoring of these effects is a challenging task that is impossible to carry out only with field observations. For this reason, a wide remote sensing observation repeated during time allows us to have an integrated view of the environmental evolution after large magnitude earthquakes. The aim of this PhD project is to develop an automatic remote sensing technique for detecting the temporal evolution of physical parameters at the surface (e.g., displacement, temperature, humidity) before and after a large earthquake. To this aim, multispectral data from satellites of the Copernicus Program will be used. The ultimate goal is to mitigate the hazard associated with the environmental effects induced by large earthquakes. The case study will be the 2016 central Italy earthquake, where a large amount of data is available. The industrial partner is the “Eagleprojects” company, which is specialized in remote sensing and big data analysis.

Titolo: Depositional evolution of a space-time migrating foredeep through a multidisciplinary/multiscale approach: an example from the Marnoso-Arenacea basin (Northern Apennines, Italy)

Descrizione: In the Umbria pre-Apennines a comprehensive and updated synthesis of the depositional architecture and the structural setting of the Miocene foredeep succession is still lacking. Also the deformation times have been only roughly defined, except for some limited sectors. Another important but underdeveloped issue regards the values of sedimentation ratios over time and under the influence of the emplacement of the Tuscan-Ligurian allochthon and the activity of possible syn-sedimentary normal faults active in the foreland. Defining the relationships between the different tectono-stratigraphic units, and integrating them with literature biostratigraphic data, will allow to constrain the sedimentary evolution, the physiography of the basin and the timing of the deformations. Further aims of this work are to provide constraints to the burial history of the Miocene foredeep. The final synthesis of the project will be an attempt to apply methods of basin-analysis to the entire Marnoso-Arenacea foredeep. This objective will be pursued through a multidisciplinary approach, integrating field mapping, detailed stratigraphic and structural analysis, and the interpretation of any available seismic reflection line that crosses the study area also aided by three-dimensional modeling techniques.

Titolo: Characterization of CO2 Geological Reservoir Storage

Descrizione: La maggior parte dei reservoir carbonatici sono stati utilizzati per l’estrazione di idrocarburi per le loro favorevoli caratteristiche come porosità e permeabilità, ma solo recentemente i ricercatori hanno compreso il potenziale di queste formazioni come strumenti per contrastare i cambiamenti climatici. Da questo punto di vista i reservoir carbonatici, noti per essere chimicamente molto reattivi una volta entrati in contatto con la CO2, sono stati scarsamente studiati. Per questo motivo, l'obiettivo del dottorato di ricerca sarà quello di comprendere appieno il comportamento e l'interazione tra la CO2 iniettata e la roccia ospitante dal punto di vista petrofisico, mineralogico e geochimico.
