The project GEOTREF intends to study the geothermal potential in the lesser Antilles. This
necessitates a better knowledge of the arc volcanism. The onshore structure of volcanoes
have been intensely studied and monitored in contrast with the offshore and submarine
structure that remains deeply unknown. Bathymetric charts from previous cruises along the
lesser Antilles arc revealed the presence of many submarine volcanoes, some of them with a
well preserved morphology.
Collect rock samples on the flank of submarine volcanoes located to the south of Montserrat.
