You keep using that word...I do not think it means what you think it means:

Transocean Ltd. had its "best year in safety performance" despite the explosion of its Deepwater Horizon rig that left 11 dead and oil gushing into the Gulf of Mexico, the world's largest offshore-rig company said in a securities filing Friday. far, far greater:

The death toll of animals that perished as a result of the Deepwater Horizon/BP oil spill in the Gulf of Mexico may be 50 times higher than presently believed, according to a new study in the latest issue of Conservation Letters.

Until now, fatality figures have primarily been based on the number of recovered carcasses. Data on this varies depending on the source and the date of the count, but the authors report that as of Nov. 7, 2010, 101 whale, dolphin, and porpoise carcasses had been detected across the Northern Gulf of Mexico.

Past numbers of carcasses reflect just 2 percent of actual animal deaths, according to the study, so the true number of fatalities for cetaceans alone as a result of the spill could be in the thousands.
