Insights into Trace Gas Biogeochemistry Research

We will provide an overview of trace gas biogeochemistry research in GEOMAR. Furthermore, we will be discussing our doctoral research projects on NO and CO measurements in the ocean and how we end up with our ASSEMBLE+ Transnational Access project at CCMAR.

Nitric oxide is rarely measured in the ocean due to its high chemical reactivity which leads to a very short life time and thus low concentrations. Studying NO, however, is vital in understanding the nitrogen cycle since NO is a short-lived intermediate of denitrification, nitrification, and anaerobic ammonium oxidation. It is also an intermediate and potential precursor of nitrous oxide –a strong greenhouse gas in the troposphere and a major ozone depleting compound in the stratosphere. 

Meanwhile, carbon monoxide plays an important role for the oxidizing capacity of the Earth’s atmosphere. In the troposphere, CO reacts fast with OH and, when NOx is present, it leads to the formation of ozone a strong greenhouse gas. Because of its reactivity with OH radicals, CO also indirectly influences the lifetime of atmospheric methane, another potent greenhouse gas.

 

The seminar will be held on June 04, at 13:30, online via Zoom platform.
