| Zusammenfassung |
| A new project called MeSMarT (Measurements of shipping emissions in the marine
troposphere) to estimate the influence of ship emissions on the chemistry of the atmospheric
boundary layer over the North Sea has been established in cooperation with the
German Bundesamt für Seeschifffahrt und Hydrographie (Federal Maritime and
Hydrographic Agency). Over the last years discussions about ship emissions have
increased and grown in importance due to the increase of commercial shipping as
well as studies about their dangerous health effects. While industrial and traffic air
pollution from ashore is decreasing because of technological improvements and
stronger political regulations the impact of ship emissions becomes more relevant,
especially in coastal areas and harbor cities. The establishment of a Sulfur Emission
Controlled Area (SECA) for the North Sea and the Baltic Sea has been a first step to
control and reduce ship emissions by consecutively regulating the sulfur content of
fuels.
The project MeSMarT aims to monitor background concentration as well as elevated signals
of gases and particles related to ship emissions with various physical and chemical methods
to cover a wide range of relevant pollutants and their spatial and seasonal distribution. SO2,
NO2, NO, CO2 and O3 are measured with in situ techniques, SO2 and NO2 as well by remote
sensing applying the MAXDOAS-technique. The data will also be compared with satellite
measurements and passive sampling in order to find a method to observe the long-term effect
of regulations like SECA. High volume filter samples will be taken and analyzed especially
for sulfate, nitrate, organics and elemental composition to investigate possible sources, sinks
and conversion of ship emission derived compounds. Measurements and sampling take
place during ship campaigns primarily in the North Sea and will be complemented
with stationary measurements located on a coastal site close to the main shipping
routes through the German Bight. Modeling of pollutants transport and chemical
transformation taking into account the measured data will also be included in the MeSMarT
project to improve the understanding of the relevance of ship emissions in coastal
environments.
Here we present a project outlook and first results of a campaign in late 2012 using both in
situ and remote sensing techniques. |
