The southwestern Gulf encompasses two major geological provinces, each with distinctive topographic features: In the next nine months, experts and divers including Red Adair were brought in to contain and cap the oil well.

Oil platforms in operations, showed drastic fluctuations of oil degrader percentages in surface waters and sediments with no clear seasonal pattern. Save my name, email, and website in this browser for the next time I comment.

The ixtpc national research institutions in Mexico participated in implementing a short and midterm strategic observational plan to detect the environmental disturbances caused by the crude oil in the different ecosystem compartments: 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.

From a strictly environmental perspective, the Ixtoc-I blowout experience has served as an example of the imperative need to strengthen the prevention and emergency procedures of the international oil and gas operations in offshore waters. Booms were placed across inlets to prevent the oil from getting into the fragile nursery areas of the Laguna Madre behind the barrier islands. The oil caught fire, and Sedco burned and collapsed into the sea.

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.

The authors of this contribution, motivated by the current interest in finding out about the oil spills long-term effects in the marine ecosystem, offer their own views based on their experience by assessing the Ixtoc-I blowout from different perspectives.

Due to its high biodiversity, living resources, urban and industrial expansion and energy resources, this region has been considered strategic in the national plans for the social and economic development of Mexico.

The lack of a baseline data bank and a reliable source on the space-time variability on a number of environmental parameters preclude any efforts focused on reaching a conclusive answer concerning the mid-and long-term ecosystem response to a catastrophic oil spill.
