The Vitória-Trindade Chain of seamounts extends some 1200 km from the eastern continental shelf of Brazil out to the oceanic islands of Trindade and Martin Vaz. These 17 seamounts rise up around 2,500 m from the seafloor, topping out at between 50-110 m below the sea surface, and are home to reef ecosystems and associated fish communities. Seamounts are generally known to be hotspots of biological diversity, but relatively little is known about the marine life around these undersea mountains. iAltantic’s iCorsage expedition, planned for 2021, will undertake extensive geological and biological surveys of these seamounts to better understand their ecology and dynamics.
