Riki-Ott1 Follow the oil and follow the oil money! That's the theme of today's program as we check in with Dr. Riki Ott, still at her command post in the Gulf of Mexico where several inches of oil have been discovered on the seabed floor between the site of Deepwater Horizon disaster and the coastline.

We'll find out what that portends for the marine ecosystem as well as what's happened to fishing and tourism in the wake of the great oil kill.
