International Seabed Authority
The International Seabed Authority was formed in 1994 under United Nations Convention on the Law of Sea (UNCLOS). The authority organizes, regulates and controls mineral related activities in the International Seabed area. The Authority became an observer at the UN in 1996.

The Headquarters of International Seabed Authority (ISA) is situated in Jamaica. It has 167 members.
