Veronique Greenwood, The Atlantic, writes about the gas compressors in the San Juan Basin of New Mexico and the effect they are having on desert insects. The San Juan Basin is “the nation’s second-largest natural gas field, [where] for miles in every direction, gas compressors are running more or less constantly, filling the desert with their eerie, broadband roar.” When compressors are near people, Greenwood reports, efforts are made to dampen the sound, but not so when the only thing that can hear them are the creatures that live in the desert.
What do the compressors sound like? Greenwood says that they “create a curiously oppressive noise, with both high and low frequencies at very high volume, running 24 hours a day, seven days a week, nearly 52 weeks a year.” Sounds hellish. And apparently desert insects agree, as ecologists have discovered that many insect groups are disturbed by the compressors “and by high decibel levels of noise in general.” How disturbed? Although some insects groups showed no change, “[t]here were 24-percent fewer grasshoppers in compressor plots, 52-percent fewer froghoppers, and a whopping 95-percent fewer cave, camel, and spider crickets.”
The long-term effects aren’t exactly known–one researcher noted that the study was “is just the very tip of the iceberg”–but as insects avoid the sound of man-made noise, their altered behavior will likely affect the bats and birds that eat them.
