Instrument trailers are essential data recording platforms for scientific analysis of each test.
Cameras mounted inside a truck:
The Project GNOME water tank and ground shock spring instrument wall are seen to the upper right:
5 chemical bombs were detonated 4000 feet (1219 m) below the water near the San Catalina Islands, off the coast of San Diego, California.
Ground zero at the GNOME site near Carlsbad, New Mexico:
A camera was mounted in shock-resistant device when the ground violently heaved up from below, as the ball measured the displacement:
Data capture trailer at GNOME:
Ground shock gauge:
Electromagnetic pulse effects antennas:
Loop antenna resonance optimizes as the antenna loop circumference reaches one wavelength of the source electromagnetic signal.
Oscilloscopes capture weapons signal events in microseconds
Typical nuclear shots involved dozens if not hundreds of individual experiments:
A Chevrolet 3600 pickup truck? The 3600 series sold from 1952 to 1962:
Still photography of ground shock displacement effects was integral with data collection:
This test left a visible subsidence crater:
The brown shirt above needs work.
Oak Spring Butte loomed in the distance, behind Sedan, viewed from southwest to northeast on Yucca Flat:
Sedan ended in a crater is 100 m (330 ft) deep and a diameter of about 390 m (1,280 ft):
