The project MeSMarT (Measurements of Shipping Emissions in the Marine Troposphere) is a cooperation between the University of Bremen and the Federal Maritime and Hydrographic Agency (BSH).
The BSH conducts regular oceanographic and chemical surveys in North and Baltic Sea on-board the Irish research vessel Celtic Explorer for the assessment of the North Sea status. Atmospheric trace gas measurements with optical remote sensing (MAX-DOAS) and in situ gas analyzers have been performed on several cruises since 2012 by the MeSMarT-Team to additionally monitor the marine air quality.
Marine air pollution sources are mainly emissions from ships and oil rigs but also polluted air masses from land.
Here we present MAX-DOAS measurements of nitrogen dioxide (NO_2), sulfur dioxide (SO_2), formaldehyde (HCHO) and glyoxal (CHOCHO) in North and Baltic Sea, which have been evaluated and compared to simultaneous measurements from our in situ instruments as well as measurements from satellites.
