The Bahamas says just over 200 gallons (757 liters) of diesel spilled into the ocean during a refueling accident.
The owner of a salvage company has estimated that the Sunday spill near the main harbor in Grand Bahama was roughly 1,000 gallons (3,785 gallons), but the government put their estimated figure lower on Monday.
Transport Minister Glenys Hanna-Martin told reporters that some 210 gallons (795 liters) of fuel splashed between a tanker and a barge during refueling at dawn Sunday. The spill went unnoticed for about a half hour.
Crews with the Bahamas Oil Refinery Company deployed teams to contain the mess. A cleanup operation is ongoing.
Last month, roughly 3,000 gallons (1,355 liters) of oil spilled into the ocean from a cargo ship accident off Grand Bahama.
