The blast at the Ixtoc oil well off the coast of Mexico in caused the largest ever peacetime oil spill – and has similarities to the current spill. On June 3, , the Ixtoc I exploratory well in the Bay of Campeche, blew out. It was finally capped on March 23, , days later, but during that time On June 3, the Ixtoc I,located in the Bay of Campeche in the Gulf of Mexico, exploded and caught fire at AM. The Ixtoc oil spill.

The Ixtoc oil spill of fundmentally changed the way we look at oil spills.

Those authors attribute the present reduced fish diversity and ixgoc to hypoxia, climate change, oil and gas exploitation and overfishing.

The success rate is low, but the rewards are great. In spite of these actions, the fate of the coastal and marine resources in Campeche Sounds is still uncertain. Study of the penaeid shrimp population in relation to petroleum hydrocarbons in Campeche Bank.

Unfortunately, this accident was the world’s first- massive oil spill occurring in offshore waters of xitoc tropical environment. A suggested local regions in the Southern Gulf of Mexico using a diatom data-base — and oceanic hydrographic features. AGT Editorial Regionalization of the Gulf of Mexico from space-time chlorophyll- a concentration variability.

In the aftermath of this dreadful accident, a growing concern emerged not only for the oil acute effects but also for the long-term environmental consequences derived from the residual hydrocarbon compounds accumulated in coastal environments of the southern Gulf of Mexico.

However, there is a consensus in accepting that acute toxic k are space restricted and of short duration, whereas, the mid- and long-term or sublethal stress are more difficult to assess and eventually become non-detectable Burns and Yelle-Simmons, This particular sector of the Gulf is oceanographically complex and dynamic.


In the particular case of the Ixtoc-I oil blowout, the reconstruction of ecological scenarios to assess the environmental damages detected in the southwestern Gulf of Mexico is a major challenge. However, contrary to the official position of Mexican agencies that adamantly insisted that no environmental damages were caused by Ixtoc-I, oil residues remained in the water and sediments.

Stationed on the northern tip of the Padre Island National Seashore, we listened for the pinging of the buoys every two hours as they drifted northeast, and, using triangulation, established the exact location of each buoy.

The authors of this contribution offer their views on this environmental riddle from their own perspective as direct witnesses of the Ixtoc-I environmental tragedy.

At a rig in the Bay of Campeche in the southern Gulf of Mexico the unthinkable happened. As PeMex and Sedco argued over the best course of action oil began to build up in the west well column. No intentions from the Mexican government to support a long-term research program to assess the ecological damages derived from one of the largest oil spills in history were ever expressed.

In Campeche Sound there coexist three of the most important penaeid stocks exploited in the Gulf of Mexico: Coastal Education and Research Foundation, Inc.

Ixtoc I oil spill

However, at the PEMEX’s offshore oil-extraction area, drastic changes in this index were recorded bimonthly, with no indication of an increase in the oil concentration, particularly at the most active platforms.


Investigations along the Texas coast show that approximately metric tons of oil or less than 1 percent was deposited there. Two pressure relief wells were drilled and, finally, after an estimated 3 million barrels of oil entered the Gulf, the flow rates were brought under control and eventually stopped. The rest of the oil, aboutmetric tons or 25 percent, sank to the bottom of the Gulf.

The main fishery resource in this region of the Gulf, the penaeid shrimps, has experienced a declining production trend since the late s, but despite all the fishery management regulations implemented sincethe pink shrimp population, which sustains this fishery, is at a great risk of suffering a collapse.

On the shelf of Campeche Sound, the high oxtoc of oil degraders corresponded to areas directly exposed to river plumes.

Such conclusions have no bearing on intertidal or littoral communities, which were not ixtco subject of this study. One should o the complications involved in offering unequivocal evidence of environmental damages caused by accidental oil spills knowing in advance the physicochemical and biological processes acting at different spatial and temporal scales. As a graduate student working on Padre Island during the summer ofI was among the first to witness the oil from the Ixtoc I spill coming ashore on the coast of Texas.
