GNGTS 2024 - Atti del 42° Convegno Nazionale

Session 3.1 GNGTS 2024 - seismic microtremor investgatons - current meter surveys - investgatons of temperature and salinity parameters For the following purposes: ● Assessment of Energy Producton Potental from marine waves moton; ● Assessment of Energy Producton Potental from marine currents. The frst main aim of the MARE project is to assess the marine wave moton in terms of amplitude, frequency and seasonal stability by exploitng an indirect method widely tested in the literature. Sea waves are among the important sources of seismic noise recorded by seismic statons. The second main aim of the MARE project is to assess the current velocity characteristcs at diferent depths and estmate their theoretcal potental. The objectve is to calculate the potental energy generated from streams at diferent depth layers and detect the optmal one. The fnal objectve of the project is the producton of maps of marine energy potental indicators with diferent spatal resoluton, from a few km to a few hundred meters for the case of study proposed that will be characterized by a signifcant energy potental. For the later it will also be possible to evaluate the real amount of energy that can be extracted according to the diferent exploitaton technologies that can be used. References Ardhuin, F., et al.
