IXTOC I PDF

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.

Their prediction concerning Campeche Sound is that this region faces the greatest ecological risk because of the ongoing oil extraction and the increasing catch per unit effort. The oil had a severe impact on the littoral crab and mollusk fauna of the beaches which were contaminated.

An Almost Forgotten Oil Spill

Two pressure relief wells were drilled ictoc, finally, after an estimated 3 million barrels of oil entered the Gulf, the flow rates were brought under control and eventually stopped. These were absorbed by filtering organisms and bio-accumulated by benthic fauna such as oysters Crassostrea virginica and clams Rangia cuneata and Polymesoda carolineanaparticularly in coastal ii systems ixtod the States of Campeche and Tabasco. AGT Editorial Pemex claimed that half of the released oil burned when it reached the surface, a third of it evaporated, and the rest was contained or dispersed.

No use, distribution or reproduction is permitted which does not comply with these terms. Ever since the oil and gas exploration and extraction conducted by the Mexican oil consortium PEMEX expanded its offshore operations in the SW Gulf inthere has been an immediate concern for the socio-economical and environmental transformation that the presence of this aggressive industry would have upon the local communities.

Ixtoc I Oil Spill

Additionally, the tropical shelf ecosystem displayed its remarkable resilient capacity by absorbing, in time and space, the severe anthropogenic disturbance. Factors like the spilt oil volume, the high carbon content, anoxic conditions that hinder microbial degradation ixttoc a low-energy environment may all contribute to the indefinite persistence of hydrocarbons in sediments Reddy et al.

Historically, the fishing resources of the Gulf of Mexico have presumably been kxtoc to chronic oil effects for an extended period. Presently, there are still many environmental uncertainties in relation to the persistence and weathering factors of crude oil in the marine ecosystem.

Study of the penaeid shrimp population in relation to petroleum hydrocarbons o Campeche Bank. The United States was given 2 months to prepare for the oil slick from the Bay of Campeche and arranged a idtoc to protect the Texas coast.

Several authors have argued, in an attempt to understand the immediate ecosystem response to a massive oil spill caused by the Ixtoc-I blowout, that its first critical phase was perhaps progressively alleviated by a weathering process activated by local atmospheric, hydrological and biological conditions prevailing in the southwestern Gulf of Mexico. Oiled sand was scraped from beaches.

In recent times, the environmental conditions in the southwestern Gulf of Mexico have been further aggravated by the rapid expansion of PEMEX’s coastal and offshore operations. These references in addition to the results on the abundance in fish numbers and biomass, correlated with diversity and abundance indices were enough information to establish that the oil spill impact was almost absent 30 years ago in the short-time period before and after the Ixtoc-I blowout.

Few in the U.

The oil and gas fumes exploded on contact with the operating pump motors, starting a fire which led to the collapse of the Sedco drilling tower. On the seasonal phytoplankton concentration and sea surface temperature cycles of the Gulf of Mexico as determined by satellites. This river runoff represents a chronic input of hydrocarbons in Campeche Sound and has a seeding effect of HCB in this area. Unfortunately, the Macondo oil spill off the coast of Louisiana is a painful reminder of the great risk involved for human lives and the health of the marine ecosystem and the growing expansion of the oil explorations in fragile environments.

July Learn how and when to remove this template message. Archived from the original on 10 May The oil on Mexican beaches that the authors observed in early September was calculated to be ixtov metric tons.

The separation of the different biological stages and the trophic dynamic about different habitats suggest close ties between fishes, the specific characteristics of their habitats and trophic dynamics, masking iixtoc vulnerability to oil exposure.

Ixtoc I oil spill – Wikipedia

Another lesson learned from the Ixtoc-I blowout is that the pelagic realm recovers faster from a massive oil spill than the benthic compartment. The drilling mud was followed by a large quantity of oil and gas at an increasing flow rate. This article possibly contains inappropriate or misinterpreted citations that do not verify the text. On the positive side, new research lines genetics and molecular biology are beginning to shed some ixroc on this problem.

Microbiological data indicate that the ixoc on surface waters and sediments caused by seasonal or sporadic oil inputs produces seasonal or rapid and drastic changes in oil-degrader percentages both in coastal lagoons and the offshore oil-production area. In Campeche Sound there coexist three of the most important penaeid stocks exploited in the Gulf of Mexico: However, there is a consensus in accepting that acute toxic effects 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, Leave a Reply Cancel reply Your email address will not be published.

Searching for the reservoir in an excellent prospect, nearly two miles below the sediment surface, the Ixtoc I well was in about feet of water. However, lack of information about the oil spill made it difficult to assess the damage done. Pemex contracted Conair Aviation to spray the chemical dispersant Corexit on the oil.
