The Coast Guard said Saturday that an area of discolored water near a Mississippi River pass south of New Orleans appears to be an algae bloom, but another spot 10 miles away could be oil.


Jeff Hall, spokesman for the Unified Area Command, said tests could determine if the suspected oil is from the BP spill. The Coast Guard sent two flights over the West Bay area near Venice on Saturday. Two boats also went out to check the waters.
