Infrasound

A 4-element infrasound array located on Sand Island of Midway Atoll. The I58US array was installed in 2013. All array elements are installed on a concrete surface, and the wind-noise-reducing pipe array is is buried under 2” of river rock to protect it from damage from birds. This is important because nearly 3 million birds nest on the 1,500 acre Atoll each year.
