It may be hard to believe the legend that sailors long-at-sea once considered manatees to be mermaids. The manatee nickname – the “Sea Cow” – which comes from the herbivores’ affinity for grazing on vegetation and their slow, ambling way just makes more sense. But a U.S. Geological Survey video reveals that while they may be cow-like, they also have more than a bit of the magical mermaid to them.

Coastal communities count on beaches for recreation and for protection from large waves, but beaches are vulnerable to threats such as erosion by storms and flooding. Whether beaches grow, shrink, or even disappear depends in part on what happens just offshore. How do features like shifting sandbars affect waves, currents, and the movement of sand from the beach to offshore and back?
