– US Naval Institute Proceedings – The first draft of the United Nations Convention on the Law of the Sea (UNCLOS) was completed in 1982. The treaty provided a broad legal framework governing movement on the sea and the proper handling of sea-based resources. By 1994, treaty revisions had alleviated U.S. concerns regarding deep seabed mining. President Bill Clinton signed and forwarded it to the Senate for advice and consent, but it was never ratified.
