Kiel marine scientists publish new data on greenhouse gas emissions

22 June 2015/Kiel. In addition to carbon dioxide there are plenty of other greenhouse gases. Nitrous oxide is one of them. However, a global assessment of emissions from the oceans is difficult because the measurement methods used so far have only allowed rough estimates. Using a new technology for continuous measurements, researchers of the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Christian-Albrechts-Universität zu Kiel have now discovered that nitrous oxide emissions from the Southeast Pacific are much higher than previously thought. They publish their data in the international journal
Nature Gesoscience.
