Tim and moby ships9/16/2023 TIM: What are you talking about? I just described it like, 30 seconds ago. It's not powered by wind at all, but by temperature and density.Ī world map shows a system of currents looping across the oceans. Anyway, deep beneath the ocean surface, there's another current system. TIM: Yeah, it’d be nice if we drifted ashore in Hawaii. Hawaii is located in the tropics, but its climate is slightly cooler than other tropical locations, since the California Current, brings cool water south.Ī map of the United States and the Pacific Ocean shows how the direction of the California Current circulates cooler air around the Hawaiian islands. TIM: Currents can make for colder climates, too. That's why the winters are warmer in France!Īn animation shows how the gulf stream reflects the heat from the sun and turns it into warm air. TIM: In the North Atlantic, the Gulf Stream radiates heat into the atmosphere. TIM: Parisians can thank a current called the Gulf Stream for that: it delivers warm water from the tropics to Western Europe!Īn animated world map shows how the gulf stream directs warm water from the tropics toward Europe. Side by side images show a woman in Montreal bundled up in a heavy parka with snow falling and a man in Paris wearing an open jacket under a cloudy sky. But winters in Paris are a heck of a lot nicer than winters in Montreal.Ī map shows that Paris, France, and Montreal, Canada, are on the same latitude. TIM: If you look at the map, you'll see that Paris, France, is at about the same latitude as Montreal, Canada. The world map shows the direction the gyres rotate in the Northern and Southern Hemispheres as Tim describes. Surface currents have a major effect on climate and weather conditions.Īn animated popup shows the earth rotating. That makes gyres rotate clockwise above the equator, and counter-clockwise below it. TIM: The rotation of the earth causes the winds to deflect off to the right in the Northern Hemisphere, and deflect off to the left in the Southern Hemisphere. You might not know this, but some winds blow across the ocean in the same direction all year round!Īn animation shows the direction of the wind in different oceans. TIM: Surface currents are mainly caused by wind. And each gyre is bordered by one or more continents.Ī world map shows the location of the gyres in the oceans. TIM: If you look closely, you'll see that the currents actually move in large circular patterns called gyres. TIM: Fortunately, I brought my map of ocean surface currents with me. But surface currents only affect the uppermost 100 or 200 meters of water.Īn animation shows the surface currents as Tim describes. TIM: The ocean can be thousands of meters deep. Ocean currents help ships, animals, and bottles move around the globe.Īn animation shows a ship, sea turtle, whale, and bottle moving in the ocean. The waters off the world's oceans are always on the move. TIM: She's asking about ocean currents? Oh, all right. Vivian, does your mom know that we got shipwrecked? And that we've been drifting around aimlessly for a week? Please, tell your mom to call the coast guard. TIM: Dear Tim and Moby, my mom said you might get this message if I put it in the ocean. Tim retrieves the bottle and reads from the typed letter. This game is getting kind of boring.Ī bottle with a letter inside of it floats by the boat. TIM: I spy, with my little eye, something that's blue. Text reads: The Mysteries of Life with Tim and MobyĪ boy, Tim, and a robot, Moby, face each other in a small boat.
