Terms | Definitions |
|---|---|
rogue wave | a giant wave formed from the intersection of 3 or more wave crests |
wavelength | distance from one wave crest to the next, or from one wave trough to the next |
crest | the highest part of a wave |
trough | the lowest part of a wave |
surface currents | Streamlike movements of water on or near the surface. Formed by global winds, and influence by the Coriolis effect and continental deflection. |
deep currents | Streamlike movements of water far below the surface. Formed when water at the surface increases in density from higher salinity or lower temperatures, and sinks. |
salinity | a measure of the amount of dissolved salts in a given amount of liquid |
wave height, or amplitude | the vertical distance from the crest to the trough of a wave |
wave period | the time it takes one full wave, one wave length, to pass a fixed position |
deep-water waves | Waves that occur in water that is deeper than half their wavelength |
longshore currents | Currents that runs parallel to the shoreline; caused by waves colliding with the shore at an angle. |
tsunami | A wave formed from a large volume of sea water being displaced up or down, from an earthquake, landslide, meteor impact, or volcanic eruption. |
storm surge | a local rise in sea level near the shore that is caused by strong winds from a storm, such as those from a hurricane |
tidal range | Is the difference in height between a high tide and the next low tide. |
tidal bore | A body of water that rushes up a narrow bay, estuary, or river channel during the rise of high tide. |
spring tide | A tide that occurs when the sun, Earth, and moon are aligned, and is characterized by the maximum tidal range. |
neap tide | A tide that occurs when the sun, Earth, and moon form a right angle, and is characterized by minimal tidal range. |
Bay of Fundy | A body of water in Canada with the greatest tidal range on Earth. |
Hilo, Hawaii | City that was damaged from a tsunami caused by an earthquake in Chile in 1960 |
Lituya Bay | The site of the biggest tsunami, July 10 ,1958, measuring 524 m. |
jetty | A wall built out into the ocean, perpendicular to the shore, designed to trap sand moving along the shore. |
generator | a device that uses magnetism to convert energy of motion into electrical energy |
turbine | large wheel that rotates when pushed by water, wind, or steam, and provides energy to a generator |
Rance River, France | site of the largest tidal power plant in the world |
