For millennia, the exchange of CO2 (carbon dioxide) between the ocean and atmosphere has been in balance. Now, with more human-caused, or anthropogenic, carbon-dioxide in the atmosphere, the ocean is taking up more CO2 as well. This additional CO2 is negatively impacting sensitive ecosystems and scientists worry how changes to the ocean environment will affect the way carbon is cycled through the seas. Tune in to Changing Seas The Fate of Carbon, which features BIOS scientists working on the Bermuda Atlantic Time-series Study (BATS), which has collected data on the physical, biological, and chemical properties of the ocean since 1988. Learn how these measurements are helping us learn more about the role of carbon, and the ocean, in Earth's changing climate.
