Disk contains two episodes**:
Tidal Seas (49 min) The sun and moon move billions of tons of water with every turn of the tide. The strongest tides empty entire bays, smash trees on riverbanks, and strand sea creatures on suddenly dry land. Weaker tides control the movements of huge numbers of fish, coaxing schools of giant stingrays through astounding underwater arches. And as the water recedes, the tide can create unbelievable landscapes -- like a sparkling world of salt crystals inhabited only by tiny shrimp and bright pink flamingos.
Coasts (49 min) From rocky cliffs to gentle dunes, the coasts are always changing. Day in and day out, they are battered by crashing waves. Seabirds come here by the thousands to nest, while baby turtles hatch and race to the sea, pursued by hungry predators. Young sea lion pups are born and play on the sand -- until a killer whale attacks, crashing in on the surf. But when breeding season is over, life returns to the sea and the shores are empty once again.
**Included in the DVD Extras section is Deep Trouble (49 min): a compelling exploration of man's impact on the Earth's oceans.
