With sick and dead dolphins turning up along Louisiana's coast, federal regulators are curbing an oil and natural gas exploration company from using seismic equipment that sends out underwater pulses known to disturb marine mammals. The Bureau of Ocean Energy Management has told Global Geophysical Services Inc. to not conduct deep-penetration seismic surveys until May, when the bottlenose dolphin calving season ends. The agency says the surveys are done with air-guns that the emit sounds that could disrupt mother and calf bonding and mask "important acoustic cues."
