Description :
This paper reports the results of the Remotely Operated Vehicle (ROV) exploration combined with multibeam data, providing new information about the main morphological characteristics of the Nisyros submarine volcanic centres. ROV exploration of the eastern flank of Yali revealed wave-type sediment structures, as well as linear fractures at various depths. Several smaller craters were also discovered on the northwest slopes of Strongyli, aligned with ENE-WSW trending fractures with no signs of hydrothermal activity. Heavy biogenic encrustations cover the volcanic rock outcrops on the flanks of both Yali and Strongyli. Analysis of recovered samples will provide information about their relationship to the geology of the nearby islands.
