A new mathematical formula that could be used to give advance warning of where a tsunami is likely to hit and how destructive it will be has been worked out by scientists at Newcastle University. The research, led by Newcastle University's Professor Robin Johnson, was prompted by the 2004 Boxing Day tsunami disaster which devastated coastal communities in Indonesia, Sri Lanka, India and Thailand. In this instance, an earthquake in the depths of the ocean triggered a long surface wave which...

Wind and wave data from ESA's Envisat satellite radar are being used to observe meteorological conditions in the track of the Vendee Globe solo round-the-world yacht race. CLS, a subsidiary of the French Space Agency (CNES), acting through its new radar applications division (formerly the BOOST Technologies Company), is using the race to demonstrate the ability of Envisat radar imagery to operationally observe oceans at high resolution. Based on the trajectory and speed of the boats, CLS is...

We're starved for clean energy when it is all around us, in the air, water and even the earth. We'd have plenty if we could figure out how to collect it. But technological development must overcome some formidable challenges, especially to mine the powerful energy in water. Water is much denser than air, so harnessing even a small amount of the tidal current flowing in and out of our region's many bays and estuaries, or the deep-ocean currents such as the Gulf Stream, can produce vast...

By Kristin S. Agostoni An artificial reef that was supposed to help bring surfable waves back to Dockweiler Beach is slated for removal within the coming weeks, ending an experiment that began more than a decade ago. The environmental group that constructed the V-shaped reef with 200 massive sandbags will start preparation Tuesday to pull the heavy sacks from the water, a spokesman said. Despite hopes that the country's first artificial surfing reef would generate waves in a...

The European Space Agency said its Earth observation satellite Envisat is being used to help track Hurricane Ike as it travels across the Gulf of Mexico. Knowing the strength and path of hurricanes is critical for issuing timely warnings, the ESA said, and satellites are key means of providing synoptic data on the forces that power such storms, such as cloud structure, wind and wave fields, sea surface temperature and sea surface height. "Thanks to Envisat's unique capability to acquire...

Residents along the Gulf Coast are bracing for Hurricane Ike as it travels over the Gulf of Mexico after ripping through Cuba and Haiti. ESA's Envisat satellite is tracking the storm, which is forecast to make landfall on the Texas coast by 13 September. Knowing the strength and path of hurricanes is critical for issuing timely warnings. Earth observation (EO) satellites are key means of providing synoptic data on the forces that power the storm, such as cloud structure, wind and wave fields,...

Scientists said on Wednesday that Australia's vast coastline is increasingly being battered by destructive "extreme waves" driven in part by climate change. Government experts said research into wave size changes over the past 45 years showed waves of 3 meters (9.8 feet) in height or more were increasing, hitting Australia's southern coasts as severe storms become more frequent and intense. "Extreme wave conditions are greatest south of the Australian continent, associated with the passage of...

Following the extremely hot weather conditions hitting Europe, Norway experienced its biggest forest fire in the last half century earlier this month. Envisat satellite images were used in the fire's aftermath to get an overview of the damaged area for authorities and insurance companies.Extreme heat, dry conditions and strong winds quickly spread the fire in the cities of Mykland and Froland in the southern county of Aust-Agder, dampening fire-fighters attempts to squelch the blaze. Before...

Data from faint earth tremors caused by wind-driven ocean waves"”often dismissed as "background noise" at seismographic stations around the world"”suggest extreme ocean storms have become more frequent over the past three decades, according to research presented at the annual meeting of the Seismological Society of America.The International Panel on Climate Change (IPCC) and other prominent researchers have predicted that stronger and more frequent storms may occur as a result of...

Basic Ocean Terms
2013-02-05 12:52:11

Image Credit: Meteorologist Joshua Kelly When meteorologists are forecasting for ocean-going vessels, there are a few terms that we need to understand. The first term is wavelength. Wavelength is defined as the distance between two crests or between two troughs as seen in the image above. The example above highlights the crest to crest concept of wavelength. The next term that we use is wave height, and to determine this, we first must look at the wave when it passes our station. When...
