🛢 Ixtoc I oil spill

Ixtoc I was an exploratory oil well being drilled by the semi-submersible drilling rig Sedco 135 in the Bay of Campeche of the Gulf of Mexico, about 100 km (62 mi) northwest of Ciudad del Carmen, Campeche in waters 50 m (164 ft) deep. On 3 June 1979, Ixtoc I suffered a well blowout resulting in the largest oil spill in history at its time. To-date, it remains the second largest marine oil spill in history after the Deepwater Horizon oil spill.
