Isotope Analysis in Ecology

Crater measurements from two near-surface nuclear explosions detonated at Bikini atoll in 1954 were as follows: Approxmiate Crater Estimated MaximumShoot Location Yield, Radius, ft Depth, ft Mt 1 Reef 15. 3000 240 3 Island 0.1 400 75 On the basis of these and additional crater data from previous nuclear detonations, an extrapolation procedure has been developed by which crater diameters can be predicted. This procedure is based on an empirical determination of the scaling exponent, m, as a function of soil type, using R = CW1/ m, where R is radius, C is a constant related to the soil type, and W is the energy release. The range of uncertainty in the prediction of crater radius by this method is believed to be larger than a factor of 2.
