Ashes to ashes, dust to life: how iron improves anaemic oceans
Commonwealth Scientific and Industrial Research Organisation (CSIRO) Oceans and Atmosphere
Published: 5 July 2021
Scientists aboard CSIRO’s RV Investigator are studying how iron from land, including dust and bushfires, fuels phytoplankton growth in oceans. Since phytoplankton drive food webs and carbon capture, understanding iron inputs is vital for climate and fisheries.
