| Zusammenfassung |
| When a pollutant is released into the ocean or atmosphere
under turbulent conditions, even a steady release is captured by large eddies resulting in
localized patches of high concentration of the pollutant. If such a cloud of pollutant
subsequently enters a stable stratification-either a pycnocline or thermocline-then
internal waves are excited. Since large solitary internal waves have a recirculating core,
pollutants may be trapped in the sclitary wave, and advected large distances through the
waveguide provided by the stratification. This paper addresses the mechanisms, through
computer and physical simulation, by which a localized release of a dense pollutant
results in solitary waves that trap the pollutant or disperse the pollutant faster than in
the absence of the waves. |
