A PRELIMINARY ANALYSIS OF THE INFLUENCE OF SUMATRAN TSUNAMI ON INDIAN OCEAN CHL-a AND SST - Advances in Geosciences - page 20

4. Summary

The results indicate the persuasiveness of the Boxing Day tsunami on the
marine ecosystem and ultimately on the productivity of the Indian Ocean.
Together with thermal energy, nutrients were brought from below the sur-
face by upwelled water and facilitated the growth of phytoplankton. The
drift of Chl- a is obvious at times by the action of the giant waves produced
and this is also responsible for the low Chl- a along the east coast of India
and around Sri Lanka. It is thought that these waves that reached land
were highly contaminated by sludge and other wastes that, in turn, caused
a strong effect on water quality and biota of coastal as well as offshore
environments. However, the post-consequences following such a tsunami
are so catastrophic to the natural ecosystem that loss estimates and rate of
recovery times are dicult to calculate.
