| Zusammenfassung |
| While Antarctica is often described as a pristine environment, there is an
increasing awareness of the potential threats from local pollution sources
including tourist ships and emissions associated with scientific activities.
However, to date there has been no systematic attempt to model the impacts
of such pollutants at the continental scale. Indeed, until very recently there
was not even a sulphur emission budget available for Antarctica. Here we
present the first comprehensive study of atmospheric pollution in Antarctica
using a limited area chemistry climate model, and a monthly emissions
inventory for sulphur from maintenance of research stations, ground and air
traffic, shipping and the active Erebus volcano. We find that ship emissions,
both sulphurous and black carbon, dominate anthropogenic pollution near the
ground. Their prevalence is likely to rise dramatically if recent trends in
tourism continue. |
