Researchers Compare Observations Versus Modeling of Coastal Carbon Cycle

Sarah Derouin, Science Writer by Sarah Derouin 4 March 20244 March 2024

While storing carbon dioxide, the coastal ocean also releases methane and nitrous oxide. New research shows that understanding the impact of coastal oceans on climate requires more research into these fluxes and how they counteract each other.
