Paris -- Scientists say they are using satellite data to assess the damage from the Gulf of Mexico oil spill to two major bluefin tuna spawning grounds.
Atlantic bluefin tuna, among the world's largest fish, come to the gulf yearly from January to June with their peak spawning period in April and May, just when about 2 million gallons of oil a day was pouring into the ocean following the explosion of BP's Deepwater Horizon rig on 20 April.
The Ocean Foundation, a non-profit group dedicated to protecting ocean environments and species, turned to the European Space Agency and its satellites to assess the impact on the two main spawning grounds in the gulf, an ESA release said.
