There are various settings for the action of the novel. Much of the action takes place in the Washington D.C. area. This is where the meetings are held and where the Seagrams, Donner, the President, Kemper and the others are based. This is where Meta Section is directed from and where the crucial part of the salvage operation is being monitored from.
The salvage operation obvious takes place in the North Atlantic where the sunken ship lies. There are various ships that go to the area and a great deal of the action takes place undersea with the salvage crew using submersibles.
