Understanding ocean currents

New webinar covers currents and computer navigation systems

Understanding ocean currents

Having a basic understanding of tides and currents and learning how to use computer navigation software to predict their effects before and during your trip can be critical to enjoying a safe and happy cruise.

Tide is the periodic rise and fall of a body of water resulting from gravitational interactions between the sun, moon and Earth. Current refers to the horizontal movement of the water. Tidal currents are caused by gravitational interactions between the sun, moon and Earth and are part of the same general movement of the sea manifested in the tide.

All the world’s oceans have significant wind-driven currents, which are of keen interest to the nearshore and offshore navigator. For the continental U.S. these are the Gulf Stream, Labrador Current, the Pacific Current and the Alaskan Current. These currents affect route planning and create weather conditions that can become navigational hazards to the boater.

To learn more about tidal and ocean currents and how they affect navigation planning and actual passage making, register for our new webinar, Oceanography: Ocean Currents & Computer Navigation. The webinar will be held Nov. 14 at 8 p.m. EST/5 p.m. PST and costs only $20.

By taking this webinar you will learn about the history of currents in the field of oceanography, how currents are created by the world’s weather systems and Earth’s physics, how the currents themselves create weather, where to obtain planning data regarding the flow of these currents and how to obtain real-time forecasting information to use in conjunction with computer-based navigational software.
