What My Sister Means to Me

article 4 nola. com Gulf of Mexico inunct spills environmental touch on expected to be profound, long-lasting Published Fri solar day, May 07, 2010, 826 PM As the Miss Brandy shrimp boat skimmed rust- colourationed clumps of oxidize cover from Chandeleur Sound, seagulls from a flock circling nearby dived beneath a sparkle smarmy sheen on the waters surface to feed on a school of minnows Friday afternoon. The tip atomic number 18 probably coming to the surface because theyre destruction from the anele, said Larry Schweiger, president and CEO of the National Wildlife Federation. Those gulls think theyre getting a free meal when really theyre getting a load of toxins. Schweiger, who heads the nations largest preservation group, led reporters on a six-hour boat tour to survey bionomic modify caused by the Deepwater Horizon oil leak, which has been spewing an estimated 210,000 gallons of sweet crude per day into the Gulf of Mexico since the drilling rig exploded April 20. A 10 0-mile round trip from Venice to the Chandeleur Islands revealed no oil on the shorelines of several islands.However, areas in Chandeleur Sound are crisscrossed by long ribbons of degraded oil, which turns a rust color as iron in the oil is exposed to air. Once scooped from the water, the oily clumps transform into gooey dark brown globs with the consistency of molasses. Shrimp boats were deployed end-to-end the sound to skim the water with orange booms to corral the floating oil. Schweiger traced the clumping phenomenon to a termination by BP, which was leasing the rig and is in charge of clean-up efforts, to use dispersants some(prenominal) on the waters surface and below the surface to break up the oil before it can wash ashore. Using dispersants minimizes the damage to the coastline, save the oil is spread throughout the water column and probably does more damage to the fisheries, he said. The dispersants just shift the risk. Its a trade off. He applauded the decision to h alt the use of underwater dispersants on the Deepwater Horizon leak, which is nearly a mile below the waters surface, deeper than chemical dispersants had ever been used before. About 2 miles west of the Chandeleur Islands, schools of rain minnows could be seen darting beneath the floating oil. Schweiger said the fish are likely doomed. Dispersants will make oil and water mix, yet theres no way to make oil and fish mix, he said. virtually islands in Chandeleur Sound are not protected by containment booms. virtuoso notable exception is New Harbor Island, a prime nesting farming for brown pelicans because the mangrove trees enable the birds to build nests safe from lofty tides. The island is surrounded by booms, but beyond the booms were patches of oily water. You can protect the island from the oil, but the pelicans are still exposed to it when they feed on fish in contaminated water, Schweiger said. There have been several confirmed sightings of oil on barrier islands, but he oil does not appear to be staying very long, at least not in high concentrations. Schweiger pointed to a spot on Freemason Island, where he had seen oil the day before. Nevertheless, high tides had apparently washed it away by Friday afternoon, when several killdeer could be seen darting along the shoreline where the oil had been. However, Schweiger noted that little of the oil gushing from the ruptured salubrious for more than two weeks has been removed from the water. Just because you cant always see the oil doesnt mean its not there and that its not going to have a huge impact on nature, he said.
