Abstract

At the margins Continental margins are extremely sensitive to climate change, so it is important to understand how they might respond to extreme warm conditions. Changes in productivity, ocean chemistry and carbon cycling in the equatorial Atlantic during the ‘greenhouse’ climate interval in the mid-Cretaceous period point to river runoff as an important factor in the coastal ocean ecosystem. High discharge rates of continental freshwater led to dramatic changes in ocean productivity and to a lack of oxygen in the coastal ocean.
