Topic: Tides and currents

A graphic showing the frequency of tides and the tidal bulge of water due to the moon's gravitational pull. As the moon's position changes, the two tidal bulges rotate around the Earth. These bulges represent high tides, while the corresponding flatter sides indicate low tides..
Tides

Knowledge of the times, heights, and the flow of tides is of importance in a wide range of situations such as navigation through coastal waterways; construction of bridges, docks, breakwaters, and deep-water channels; and for fishing, boating, surfing, and water sports.

Ocean currents

Ocean water is on the move, affecting your climate, your local ecosystem, and the seafood that you eat. Ocean currents, abiotic features of the environment, are continuous and directed movements of ocean water. These currents are on the ocean’s surface and in its depths, flowing both locally and globally.
