Gravitational, erosional and depositional processes on volcanic ocean islands: Insights from the submarine morphology of Madeira Archipelago

- Source-to-sink approach to study the submarine flanks of Madeira Archipelago.
- Islands subaerial characteristics control the development of submarine flanks.
- A network of submarine gullies and channels dissects the islands' flanks.
- Their origin is related to hyperpycnal or storm-induced sediment flows.
- Wave and scour fields form downslope of channels by unconfined turbidite currents.
