At Lost City, the rocks, fluids and organisms are all intimately connected in ways that we do not fully understand. During this expedition, we will learn more about how the interaction between rocks and fluids supports life on and within the seafloor. We will also study larger animals that live on the chimneys to determine who they are, what part of the ocean they might have come from, and how they have adapted to live within the strange and novel environment at Lost City.
