The University of Trieste is one of five of research institutions participating in the INSIDE oceanographic mission (Unravelling the lithosphere-asthenosphere system of the Tyrrhenian back arc basin through geological, petrological and geophysical data, integration and geodynamic modelling), a campaign coordinated by the national research centre (CNR) that brings together an international team aboard the research vessel, the Gaia Blu. The campaign aim is to improve knowledge of the Tyrrhenian seabed and the underlying geological structures. 

Some of the most important activities include the measurement of terrestrial heat flow and the application of advanced seismic imaging techniques. The latter of which allows researchers to obtain high-resolution images of the bathymetry and seabed, making it possible to identify active faults, recent sedimentary deposits and ongoing deformations. Heat flow measurements, on the other hand, mean the heat rising from the Earth's mantle towards the seabed can be quantified. This is a decisive parameter for assessing the thermal state and tectonic activity of the basin.

The new data acquired is unprecedented in its accuracy and will offer new insights into the thermodynamics of the Tyrrhenian region and its relationship with seismic and volcanic phenomena.

On board the Gaia Blu are Prof. Magdala Tesauro, professor of Solid Earth Geophysics, and research assistant Dr Racine Abigail Basant, both from the Department of Mathematics, Computer Science and Geosciences. The Trieste group contributes to the choice of data acquisition points, data collection and laboratory analysis. 

'The interpretation of these results,’ emphasises Prof. Tesauro, 'will allow us to estimate the physical properties of the crust and upper mantle of the Tyrrhenian basin, achieving one of the main objectives of the project.’

The INSIDE mission is coordinated by Dr Maria Filomena Loreto of the Institute of Marine Sciences of the National Research Council (CNR-ISMAR) and involves the participation of UniTS, the Department of Earth, Environmental and Life Sciences at the University of Genoa (DISTAV), the Rome2 INGV section on 'Geomagnetism, Aeronomy and Environmental Geophysics', and the Université de la Sorbonne (UPMC, Paris).
