Dr. Silvina Botta (Universidade Federal do Rio Grande in Brazil) retrieves water samples from ROV SuBastian for stable isotope analysis—a chemical way to study how carbon moves through the ocean.

New Life Discovered Miles Beneath the Surface Off Brazil
During the 2025 Deep-sea Habitats of the Cook Islands expedition on Exploration Vessel Nautilus the team surveyed various seascapes to better understand seabed environments, and natural and mineral resources in the region. In this image, polymetallic nodules rest on sediment accumulated in a depression between rounded pillows and extended lobate lava flows, which are evidence of ancient volcanoes.
