| Zusammenfassung |
| The importance of discussions about ship emissions has grown due to the increase of
commercial shipping as well as the publication of studies showing their serious effects on
human health and on our environment. Especially in coastal areas and harbor cities the impact
of ship emissions becomes more and more relevant. The establishment of a Sulfur Emission
Controlled Area (SECA) for North Sea and Baltic Sea based on the MARPOL Annex VI
protocol by the International Maritime Organization (IMO) has been a first step to control and
reduce sulfur dioxide (SO2) emissions by consecutively regulating the sulfur content of
fuels. To reduce nitrogen oxide (NOx) emissions from shipping, the emission of
newly built engines is limited according to the year the engine is built (Tier I – III
regulations).
The project MeSMarT (Measurements of shipping emissions in the marine troposphere)
has been established as a cooperation between the University of Bremen, the German
Bundesamt für Seeschifffahrt und Hydrographie (Federal Maritime and Hydrographic
Agency) and the Helmholtz-Zentrum Geesthacht to estimate the influence of ship emissions
on the chemistry of the atmospheric boundary layer and to establish a monitoring system for
main shipping routes. Pollution relevant trace gases SO2, NO2, NO, CO2 and O3 are
measured with in-situ techniques. Within the project different measurement sites have
been set up. In Wedel near Hamburg measurements have been performed in close
distance to the Elbe River where ships entering the Hamburg harbor are passing
by. It is shown that ship emission peaks can be associated with individual ships
and how this information can possibly help to monitor the compliance of ships
with SECA regulations. On the island Neuwerk the measurement station is located
about 6 km south of the main shipping route through the German Bight. An outlook
is given on how the method of identifying ship plumes can be transferred to the
Neuwerk data and how the ship emissions influence the local marine air quality. |
