The world's glaciers are indeed melting, but a monumental study released Thursday in the journal Science discovered that it might not happen as quickly as once thought. The study notes that there are more gradual shifts in the current systems in the North Atlantic Ocean, instead of a rapid meltdown that could cause swift climate changes to Europe and other places. The research, based on a "general circulation model" that replicated the Earth's climate 21,000 years at the height of the last...

Southampton scientists have demonstrated an unexpected role of iron in regulating biological production in the high-latitude North Atlantic. Their findings have important implications for our understanding of ocean-climate interactions.Tiny plant-like organisms called phytoplankton dominate biological production in the sunlit surface waters of the world's oceans and, through the process of photosynthesis, sequester large amounts of atmospheric carbon dioxide. A proportion of the carbon is...

Satellite, Now Entering Its Second Decade, Has Revolutionized Marine Weather Forecasts "June is busting out all over," as the song says, and with it, U.S. residents along the Atlantic and Gulf coasts begin to gaze warily toward the ocean, aware that the hurricane season is revving up. In the decade since NASA's QuikScat satellite and its SeaWinds scatterometer launched in June 1999, the satellite has measured the wind speed and wind direction of these powerful storms, providing data that are...

Researchers here have used sediment from the deep ocean bottom to reconstruct a record of ancient climate that dates back more than the last half-million years.The record, trapped within the top 20 meters (65.6 feet) of a 400-meter (1,312-foot) sediment core drilled in 2005 in the North Atlantic Ocean by the Integrated Ocean Drilling Program, gives new information about the four glacial cycles that occurred during that period.The new research was presented today at the Chapman Conference on...

U.S. scientists say they have discovered a new pathway for the global ocean circulation known as the Great Ocean Conveyor. Researchers from the Woods Hole Oceanographic Institution and Duke University said the conveyor belt paradigm says the Gulf Stream-warmed ocean releases heat to the atmosphere in the northern North Atlantic, leaving ocean water colder and denser as it moves north. The cold waters then sink and flow southward along the deep western boundary current that hugs the...

A new study reported Thursday finds that lessening airborne dust has caused a rapid warming of the tropical North Atlantic in recent decades. The sun-dimming dust, blown in from sandstorms in the Sahara or caused by volcanic eruptions, reflects a portion of the sun's rays back into space.  This decline in dust was responsible for 70 percent of the warming in the Atlantic since the early 1980s, according to the study. "Since 1980 tropical North Atlantic Ocean temperatures have been rising...

A new study released Wednesday shows that large, sudden climate changes in the North Atlantic have a rapid impact on the South Atlantic, and also affect weather throughout the entire world.An international team of scientists, led by researchers at Cardiff University, found that significant, abrupt temperature changes recorded over Greenland and the North Atlantic during the last Ice Age were actually global in their extent.The new research supports the idea that changes in ocean circulation...

In the Southern Indian Ocean, climate change is leading to stronger winds, which mix waters, bringing CO2 up from the ocean depths to the surface. This is the conclusion of researchers who have studied the latest field measurements carried out by CNRS's INSU, IPEV and IPSL. As a result, the Southern Ocean can no longer absorb as much atmospheric CO2 as before. Its role as a 'carbon sink' has been weakened, and it may now be ten times less efficient than previously estimated. The same trend...

Scientists from the GKSS Research Centre in Geesthacht have developed a mathematical method that enables a reconstruction of the occurrence of small-scale polar storms - so-called polar lows - in the North Atlantic. This has made it possible to determine, for the first time, the frequency of such polar lows in the past. Subsequent statistical analysis of data generated for the last 60 years revealed no direct correlation between global warming and the incidence of polar lows. The results from...

A study reported in yesterday's issue of Nature disputes a longstanding picture of how ice sheets influence ocean circulation during glacial periods. The distribution of sunlight, rather than the size of North American ice sheets, is the key variable in changes in the North Atlantic deep-water formation during the last four glacial cycles, according to the article. The new study goes back 425,000 years, according to Lorraine Lisiecki, first author and assistant professor in the Department of...

North Atlantic Right Whale, Eubalaena glacialis
2013-08-26 11:17:56

The North Atlantic right whale (Eubalaena glacialis), also known as the black right whale or the northern right whale, is one of three right whales in the Eubalaena genus. It can be found in a small population of about 396 individuals in the western North Atlantic. If it does occur in the eastern North Atlantic, experts assert that it only numbers in the tens, making it nearly extinct in that area. This species migrates into the western North Atlantic to feed in the spring, summer, and fall...

The Humpback Whale (Megaptera novaeangliae) is a mammal, which belongs to the baleen whale suborder. It is a large whale: an adult usually ranges between 40"“50 ft (12"“16 m) long and weighs approximately 79,000 pounds (36,000 kilograms, or 36 tons. It is well known for its breaching (leaping out of the water) and its unusually long front fins. The Humpback Whale lives in oceans and seas around the world, and is regularly sought out by whale-watchers. Feeding The Humpback Whale...
