Abstract: Numerous benthic storms were observed during the Nordost-Atlantisches Monitoring-Programm (NOAMP), most of them being attributed to deep reaching mesoscale eddies. A three dimensional general circulation model is used to simulate such a storm and the resulting dispersion of dissolved matter from a bottom source in the near field around the dumpsite for low level radioactive waste in the north-east Atlantic. Realistic topography and thermal stratification are included in the model. The aim of this study is to investigate the combined effect of benthic storms and topography on the vertical transport in the deep ocean. It is shown that about half of the material is washed out of the well mixed benthic boundary layer locally and is dispersed vertically inside the eddy within 10 days.
