| Zusammenfassung |
| Nutrification of the open ocean originates mainly from deposited aerosol in
which the bio-avaliable iron is likely to be an important factor. The
relatively insoluble iron in dust from arid soils becomes more soluble after
atmospheric processing and, through its deposition in the ocean, could
contribute to marine primary production. To numerically simulate the
atmospheric route of iron from desert sources to sinks in the ocean, we
developed a regional atmospheric dust-iron model that included
parameterization of the transformation of iron to a soluble form caused by
dust mineralogy, cloud processes and solar radiation. When compared with
field data on the aerosol iron, which were collected during several Atlantic
cruises, the results from the higher-resolution simulation experiments showed
that the model was capable of reproducing the major observed patterns. |
