Gulfstream

Directed by Bruce Mackay

Traces the 2,000-mile, 15-day voyage of the Freya, a small three-hulled sailing ship, from the Bahamas to the Grand Banks of Newfoundland, following the path of the Gulf Stream. Uses animation, infrared satellite transmissions, and time-lapse photography to explain the origin, nature, and importance of the current, as well as its oceanographic, meteorologic, and ecological aspects.
