Flow: Currents and climate introduces viewers to oceanic thermohaline circulation -- the system of global ocean currents that cycle warm and cold water across the planet. This marine conveyor belt is a key mechanism in the complex exchange of energy between the oceans and the atmosphere, transferring heat from tropical regions to cooler high latitudes, and it plays a vital role in regulating Earth's climate. Flow is a new film for the Science on a Sphere system, created by the Science Museum of minnesota in partnership with the American Museum of Natural History, the Maryland Science Center, and the Institute for Learning Innovation.
