Besides the already successfully introduced usage of offshore wind energy and tidal energy within the ocean, other resources remain unused. (frontiersin.org)
Tidal currents , as their name suggests, are generated by tides . (howstuffworks.com)
This rise in water level is accompanied by a horizontal movement of water called the tidal current . (howstuffworks.com)
Tidal currents differ from the currents previously mentioned in that they don't quite flow as a continuous stream. (howstuffworks.com)
The strongest tidal currents occur at or around the peak of high and low tides. (howstuffworks.com)
When the tide is rising and the flow of the current is directed towards the shore, the tidal current is called the flood current , and when the tide is receding and the current is directed back out to sea, it is called the ebb current . (howstuffworks.com)
Because the relative positions of the moon, sun and earth change at a known rate, tidal currents are predictable. (howstuffworks.com)

Important ocean currents that redistribute heat, cold, and precipitation between the tropics and the northernmost parts of the Atlantic region will shut down around the year 2060 if current greenhouse gas emissions persist. (wordlesstech.com)

and they found that over the last half century, these currents have changed markedly. (bbc.co.uk)

Because the currents are a huge source of heat redistribution globally, a shutdown could have a complex array of consequences, from rainfall disruptions in the southern hemisphere, to even greater sea level rise on North America's east coast. (sciencefriday.com)

Researchers from the UK's National Oceanography Centre say currents derived from the Gulf Stream are weakening, bringing less heat north. (bbc.co.uk)

The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between the Americas to the west, and Eurasia and Africa to the east. (newworldencyclopedia.org)
To the east, the boundaries of the ocean are Europe, the Strait of Gibraltar (where it connects with the Mediterranean Sea , one of its marginal seas, and, in turn, the Black Sea ), and Africa. (newworldencyclopedia.org)
The width of the Atlantic varies from 1,770 miles (2,848 kilometers) between Brazil and Liberia to about 3,000 miles (4,830 kilometers) between the United States and northern Africa. (newworldencyclopedia.org)

Another new study ( Anomalously weak Labrador Sea convection and Atlantic overturning during the past 150 years by David Thornalley and colleagues) was published in the same issue of Nature , which supports this finding and places it in a longer climate history context. (realclimate.org)
For the past ca. 7.5 Kyr BP sea ice is mainly transported to the study area by local ocean currents such as the inner Labrador and Baffin Current. (lu.se)

The leading theory is that melting ice from the Arctic and Greenland could add huge amounts of cold, fresh water to the Atlantic. (wxxinews.org)

Highly productive fisheries of the Atlantic have been severely overfished in the twentieth century and the development of industrial scale fish farming raises further issues about maintaining healthy wild fisheries. (newworldencyclopedia.org)

A detailed computer modeling study released today indicates that oil from the massive spill in the Gulf of Mexico might soon extend along thousands of miles of the Atlantic coast and open ocean as early as this summer. (ecoclimax.com)
In addition to those mentioned, other large bodies of water adjacent to the Atlantic are the Caribbean Sea , the Gulf of Mexico , Hudson Bay , the Mediterranean Sea, the North Sea , and the Baltic Sea . (newworldencyclopedia.org)
The Atlantic current that includes the Gulf Stream, for example, had slowed down 15% in the last hundred years. (exploratorium.edu)

Examining 20,000 data points, the researchers showed that the Southern Ocean surface has freshened during the last 60 years. (sciencedaily.com)
Researchers at Johns Hopkins, the Maryland Sea Grant Program, and Dr. Rob Brander aka "Dr. Rip," who has a site called ScienceoftheSurf.com, have all worked with the Ocean City Beach Patrol to understand ocean conditions dangerous to swimmers and to help educate and inform the public. (oceancity.com)
Researchers have been trying to determine when the Atlantic might cross that tipping point. (vpm.org)
Aiming to simulate ocean currents in a laboratory, researchers at the Bjerknes Centre in Bergen and the University of Stavanger (UiS), both in Norway, have constructed a 4.5m high arrangement of plastic pipes, a laser, camera and measuring equipment. (optics.org)
They intend to use similar flow systems to study the ocean currents of interest to the climate researchers at the Bjerknes Centre. (optics.org)
Instead, the researchers propose biogeochemical cycles that redistribute nutrients and carbon in the ocean and on land may have influenced this rise. (eurasiareview.com)

A linear correlation exists between the retreat latitude of the Loop Current following eddy separation and the subsequent eddy separation period. (ametsoc.org)
A monster eddy current is spinning into existence off the coast of Sydney. (theconversation.com)
Giant eddy currents in the sea spread heat. (theconversation.com)
When the stratification has become so stable that the layer takes the character of a discontinuity surface, further mixing is inhibited because the eddy conductivity is greatly reduced by the exceedingly great stability (p. 476) and the amounts of heat which are conducted downwards become so small that they are carried away by weak currents. (cdlib.org)

The National Oceanic and Atmospheric Administration issues these rip current warnings based on models that the Ocean City Beach Patrol helped develop many years ago. (oceancity.com)

Concentrations in environmental media are greatest near source areas (e.g., industrial point sources, oceans and marshes, volcanoes). (cdc.gov)

The same instruments used to measure earthquakes pick up vibrations as ocean waves put pressure on the sea floor. (theconversation.com)

Research published this week found that accelerated melting from ice in Greenland is changing the speed of the Atlantic Meridional Overturning Current, which is expected to eventually destabilize, now possibly as early as midcentury. (scrippsnews.com)

Most of these organisms live in temperate to tropical oceans, especially in the Indo-Pacific regions. (medscape.com)

There are five major gyres in the world-two in the Pacific, two in the Atlantic, and one in the Indian Ocean. (listverse.com)

Basically, rip currents are simply large volumes of water trying to get out of constricted areas. (oceancity.com)

From there it is distributed to all ocean basins via the Antarctic circumpolar current. (bsocialplus.com)

Simply put, "When there is tropical activity in the Atlantic Basin, we can get rip currents in Ocean City," Arbin said. (oceancity.com)
Although the Atlantic basin was in many ways the world center of commerce in the colonial period and into the twentieth century, many signs suggest a shift of the world center of commerce to the Pacific basin in the twenty-first century. (newworldencyclopedia.org)
