EDITOR’S NOTE
The article “The Next Global Energy Powerhouse,” written by Kell Sloan and appearing in the April 2015 issue, erroneously stated that CSnet International, JAMSTEC and Pro-Oceanus Systems were working collaboratively to map the distribution of methane in the Nankal Trough. CSnet International was not involved in this effort.
