Panarea meda stakeGALLERY - The beacon positioned by INGV off the coast of the island of Panarea
A new water monitoring instrument has just been installed off the coast of the Aeolian Islands aimed at improving the quality of the marine environment

Off the coast of the island of Panarea, the National Institute of Geophysics and Volcanology (INGV) has recently positioned a medal at stake, i.e. a structure emerging from the sea which contains instruments capable of communicating analytical data taken from the marine and submarine environment to an earth station. These are the activities foreseen by the IDMAR project, the distributed multidisciplinary laboratory for scientific and technological research on the sea, coordinated by the INFN Southern National Laboratories with the Palermo Section of INGV and with the Institute for the study of anthropic impacts and sustainability in the marine environment of the CNR (IAS-CNR).
“Il IDMAR project, funded by the Sicilian Region, has the objective of creating marine research infrastructures in the 'Sea Economy' thematic area of ​​the Regional Strategy”, explains Francesco Italiano, Director of the Palermo Section of INGV and project coordinator for the Institute. “IDMAR is today the largest distributed laboratory in Europe for marine scientific and technological research and is part of a territory, the Sicilian one, which is particularly vulnerable to risks of natural and anthropic origin. Geological risks, those related to climate change or related to human activity and waste inevitably impact the marine environment, causing serious consequences for the economy, the well-being of citizens and human health".
The beacon was installed inside the underwater hydrothermal system off the coast of the island of Panarea, an area which in recent years has been affected by conspicuous phenomena of gas 'bubbles' rising to the surface which emerge from the seabed, agitating the surface of the sea. The beacon was anchored at a depth of 23 meters and wired to a fixed observatory on the seabed for the continuous acquisition of long series of chemical and physical data on the marine environment and hydrothermal fluids.
“The data acquired by our instrumentation is collected through the IT infrastructures of the multidisciplinary Monitoring Room of the Palermo Section of INGV and shared to allow the national and international scientific community to access a vast range of information on the underwater environment. The acquisition of this data provides important information on the state of the local marine ecosystem, contributing to the study of the measures necessary for the achievement of the objectives of good environmental status of the waters set in 2008 by the European Union with the Directive on the strategy for the environment marine", concludes Italian.
