Results
The results of the simulation reveals that the simulation correctly transported the
tracers south during the second half of October. Finite size Lyaponov exponent analysis shows that the flow field is
characterized by an unstable manifold separating the deep water from the coastal region and blocking the deposition
of tracers to the shore .
Conclusions
The simulation could not deposit the tracers on the shore. This deficiency in the system requires further investigation
as the deposition of pollution on the shore is likely to be of great interest to decision makers in pollution and
search and rescue (SAR) events. Several possible processes which may account for this drawback are: wind stress acting
on the tracers; wave induced currents which are unmodeled in SELIPS; diurnal or high frequency changes in the current
which are averaged out; inaccuracies in the forecasted current field near the shore.
