New measurement technology helps to determine NO concentrations in the ocean.
The gas nitrogen monoxide (NO) belongs to the group of nitrogen oxides which are infamous as toxic emissions in urban agglomerations. But NO is also produced in nature and plays a role in the nitrogen cycle, which is essential for most organisms. However, from earth’s largest ecosystem, the ocean, we have hardly any NO measurements so far. Researchers from the GEOMAR Helmholtz Centre for Ocean Research Kiel and the Collaborative Research Center (SFB) 754 now have published new NO concentration data from the eastern tropical South Pacific Ocean in the international journal Deep-Sea Research Part II, for which a newly developed measuring method was used for the first time.
