The CNS is based in the U.S and has devoted much effort into research on munitions dumps off the US coast.
“This represents only one of dozens of dumping operations conducted off the U.S. coast. So far the staff at the James Martin Center for Nonproliferation Studies (http://cns.miis.edu) have located and chronicled 127 locations where either human exposure to or disposal of chemical weapons agents and/or munitions has occurred.”
