- Abstract
Contrary to previous linear projections of steel corrosion in seawater, analysis of an inert marker embedded in USS <italic>Arizona</italic> concretion since the 7 December 1941 attack on Pearl Harbor reveals evidence that the effective corrosion rate decreases with time. The secant rate of corrosion, or <italic>SRC</italic> correlation, derived from this discovery could have a significant impact on failure analysis investigations for concreted shipwrecks or underwater structures. The correlation yields a lower rate of metal thinning than predicted. Development of the correlation is described.
