Tsunamis are not tidal waves they are very long waves generated by sudden events like earthquakes, landslides, or volcanic eruptions that displace large amounts of water.
Tidal waves are caused by the gravitational pull of the sun and the moon on the earth. The stronger the wind, the greater the pressure on the water, and generally, the larger the waves.
That is, they are created by friction between wind and surface water. These observations are part of a multi-platform observation system that scientists are using to answer questions that affect the global climate system. Waves generated in the Southern Ocean contribute to disastrous coastal flooding on tropical islands thousands of miles away and to the dispersal of plastic throughout the world ocean, and play a key role in the air-sea exchange of momentum, mass, heat, and turbulent kinetic energy.ĭuring the 2019 Saildrone Antarctic Circumnavigation, Saildrone unmanned surface vehicles (USVs) are recording a variety of meteorological and oceanographic observations in the Southern Ocean, above and below the sea surface. The Southern Ocean, with its vast expanse of open water and consistent and usually very strong winds, is home to some of the largest waves ever recorded. It’s a common misconception that waves are moving water, but they’re actually energy passing through the water.
