The Rio Grande rise is located around 1,000 km from the Brazilian coast off the southern state of Rio Grande. This submerged mountain chain has its highest point located 580 meters below the surface of the ocean in a region where the mean depth is around 4,000 meters. The Rio Grande rise is the size of the Brazilian state of Bahia and is packed with a wide variety of marine life, many of which are unknown to scientists. During the expedition researchers noticed that there was a greater number of whales and seabirds close to the rise than in other offshore areas. The project´s official name is Mar-eco Atlântico Sul, and can be considered as a sea life census.
