examines the complex systems that govern the movement tides and water levels. Learn what causes tides, what determines their frequencies and variations, and how they're monitored and measured. Find lessons on forces that affect tides and how lunar cycles affect living organisms. Use the "roadmap" to find data and predictions regarding water levels and coastal currents -- information on which maritime activities throughout the world depend.
