Gulf Oil Spill Disaster Could Change Ecosystem Of Affected Area

The oil spill at the Gulf of Mexico is killing marine food web where other marine creatures are dependent for food.

Pyrosomes, a cucumber shaped gelatinous organisms fed on by endangered turtles seen as mostly affected.

Along the coast, oil residue are being found inside the shells of young crabs which are the chief food in the diet of fish, marine turtles and shorebirds. Scientists warn the inevitable change of the ecosystem of the affected area and imperil the region’s multibillion fishing industry.

The gulf oil spill estimated to be 182 million gallons of oil and around 12 billion cubic feet of natural gas. In a 10 kilometer radius around the BP operated Deepwater Horizon rig, there is a problem that natural gas levels to have reached 100,000 times than normal, these concentration of gas are pushing down oxygen levels as the gas gets broken down by bacteria.

When oxygen levels drop low enough, the breakdown of oil and gas grinds to a halt and life can’t be sustained according to chemical oceanographer John Kessler from A & M University and geochemist David Valentine from the University of California.

In the area, dead pyrosomes were also found. The 6 inch to a foot length marine food had been believed killed by the toxins brought by the oil spill. The death of pyrosomes could set off a ripple effect especially the sea turtles and some larger fish such as tuna.

The problem is just unfolding, that toxic oil could be entering seafood stocks as predators eat contaminated marine life.
