Study Notes
Tides
- The periodical vertical oscillations of the sea are caused by the tide-raising forces of the Moon and the Sun.
- Tides are a key factor to consider when navigating a vessel into port, as they affect the available depth of the water.
- There are three main types of tides: diurnal, semidiurnal, and mixed.
- Diurnal tides have one high water and one low water per lunar day.
- Semidiurnal tides have two high waters and two low waters per lunar day.
- Mixed tides have a significant difference in the height of consecutive high waters and low waters.
- Knowledge of tidal action and how to predict and calculate the height of tide is essential for navigators.
Tidal Streams
- The periodical horizontal oscillations of the sea caused by the tide-raising forces of the Moon and Sun.
- Tidal streams can affect the speed and direction of a vessel, as they create currents in the water.
