Submarine volcanoes, seamounts and seamount-like structures are deep-sea or coastal environments that play a key role in understanding geological and oceanographic processes either at present and during the recent geological past. In deep water these structures offer unique sedimentary archives recording palaeoceanographic changes and tectonic activity. When they emerge during sea level lowstand they may act as land bridges or peculiar landscapes. Their complex morphology supports diverse and vulnerable ecosystems, enhancing biodiversity and ecosystem functioning. Despite their importance, seamounts and submarine volcanic landforms remain understudied and are highly vulnerable to human impacts due to their low resilience. Therefore, such features emerge as critical priority targets for multidisciplinary research and this session welcomes contributions on their role in Quaternary researches, addressing issues of palaeoclimate, environmental change, drowned landscapes, geological hazards and sustainable management of marine resources.
