experts and divers including Red Adair were brought in to contain and cap the oil well. An average of approximately per day were discharged into the Gulf until it was finally capped on 23 March 1980, nearly 10 months later. In similarity to the Deepwater Horizon oil spill 31 years later, the list of methods attempted to remediate the leak included lowering a cap over the well, plugging the leak with mud and "junk", use of dispersants, and spending months attempting to drill relief wells. Aftermath Prevailing currents carried the oil towards the Texas coastline. The US government had two months to prepare booms to protect major inlets. Pemex spent $100 million to clean up the spill and avoided most compensation claims by asserting sovereign immunity as a state-run company. The oil slick surrounded Rancho Nuevo, in the Mexican state of Tamaulipas, which is one of the few nesting sites for Kemp's ridley sea turtles. Thousands of baby sea turtles were airlifted to a clean portion of the Gulf of Mexico to help save the rare species. Long-term effects The oil that was lost during the blow-out polluted a considerable part of the offshore region in the Gulf of Mexico as well as much of the coastal zone, which consists primarily of sandy beaches and barrier islands often enclosing extensive shallow lagoons. The oil on Mexican beaches in early September was calculated to be about 6000 metric tons. Based on reports from various groups and individuals, five times that figure is thought to represent a fair estimate of what had landed on Mexican beaches. Investigations along the Texas coast show that approximately 4000 metric tons of oil or less than 1 percent was deposited there. The rest of the oil, about 120,000 metric tons or 25 percent, sank to the bottom of the Gulf. The oil had a severe impact on the littoral crab and mollusk fauna of the beaches which were contaminated. The populations of crabs, e.g. the ghost crab Ocypode quadrata, was almost eliminated over a wide area. The crab populations on coral islands along the coast were also reduced to only a few percents of the normal populations about nine months after the spill. A study concluded that the most persistent problems were the coastal lagoons lining the bay, as well as the pollution of estuaries. Specifically, they had problematic effects on the breeding and growth of
