The Deluge Drivers (1987) is a science fiction novel by American writer Alan Dean Foster.

The two earlier books in the series are Icerigger and Mission to Moulokin.

After resigning himself to perhaps being trapped on Tran-Ky-Ky for the rest of his life, Ethan Fortune learns that scientists at the outpost of Brass Monkey have detected a steady warming in the planet’s atmosphere.

This has caused something not seen in generations on the planet: open water on the ice oceans.

Taking the giant icerigger Slanderscree with a crew of Tran to investigate, Fortune learns that the warming of the oceans is not an accidental or natural event.
