Deep-sea hydrothermal-vent ecosystems have stimulated decades of scientific research and
hold promise of mineral and genetic resources that also serve societal needs. Some …

Marine geohazards related to geological features and processes in coastal and offshore
environments can cause damage to health, environment, field installations, or loss of life and …

Abstract Autonomous Underwater Vehicles (AUVs) have a wide range of applications in
marine geoscience, and are increasingly being used in the scientific, military, commercial …

The redox state of Earth's convecting mantle, masked by the lithospheric plates and basaltic
magmatism of plate tectonics, is a key unknown in the evolutionary history of our planet …

The impacts of large terrestrial volcanic eruptions are apparent from satellite monitoring and
direct observations. However, more than three quarters of all volcanic outputs worldwide lie …

Volcanic eruptions shape Earth's surface and provide a window into deep Earth processes.
How the primary asthenospheric melts form, pond and ascend through the lithosphere is …

Over the past 25 years, our understanding of the physical processes that drive volcanic
eruptions has increased enormously thanks to major advances in computational and …

Seafloor geodetic techniques allow for measurements of crustal deformation over the∼ 70%
of Earth's surface that is inaccessible to the standard tools of tectonic geodesy. Precise …

Since 2018, the submarine east flank of Mayotte Island (Comoros archipelago) is the site of
a major eruption located at 3.5 km depth bsl on a WNW-ESE volcanic ridge. Samples …

Deformation of the ground surface at active volcanoes provides information about magma
movements at depth. Improved seafloor deformation measurements between 2011 and …
