After 40 years of continuous experiments, the long term exposure experiment site was remodeled on Wednesday, November 11, 2014 at the PARI. The long term exposure experiment site was originally built in 1996 to evaluate the effects of erosion on concrete, metal and other materials. The renovation consists of deepening the sea water circulation tank from 2.5M to 7M and the addition of data management center. These improvements provided researchers more methods and resources to conduct the effects of long term erosion.
