Ice Age climate records from an Arizona stalagmite link the Southwest's winter precipitation to temperatures in the North Atlantic, according to new research. The finding is the first to document that the abrupt changes in Ice Age climate known from Greenland also occurred in the southwestern U.S., said co-author Julia E. Cole of the University of Arizona in Tucson. "It's a new picture of the climate in the Southwest during the last Ice Age," said Cole, a UA professor of geosciences. "When it...

Paper focuses on new tools to listen to sounds in the ocean Over the past decade, researchers have developed a variety of reliable real-time and archival instruments to study sounds made or heard by marine mammals and fish. These new sensors are now being used in research, management, and conservation projects around the world, with some very important practical results. Among them is improved monitoring of endangered North Atlantic right whales in an effort to reduce ship strikes, a leading...

High-resolution computer simulations performed by scientists at the National Oceanography Centre, Southampton (NOCS) are helping to understand the inflow of North Atlantic water to the Arctic Ocean and how this influences ocean climate. The summer of 2007 saw a record retreat in Arctic sea ice, and in general Arctic climate has become steadily warmer since the early 1990s. This has changed both sea ice drift and upper ocean circulation. The warm North Atlantic water intrudes into the central...

An international team of scientists led by the University of East Anglia (UEA) has developed a new method of measuring the absorption of CO2 by the oceans and mapped for the first time CO2 uptake for the entire North Atlantic. Published tomorrow in the journal Science, the peer-reviewed study will greatly improve our understanding of the natural ocean 'sinks' and enable more accurate predictions about how the global climate is changing. The new technique could also lead to the development of...

A chemical culprit responsible for the rapid, mysterious death of phytoplankton in the North Atlantic Ocean has been found by collaborating scientists at Rutgers University and the Woods Hole Oceanographic Institution (WHOI).  This same chemical may hold unexpected promise in cancer research. The team discovered a previously unknown lipid, or fatty compound, in a virus that has been attacking and killing Emiliania huxleyi, a phytoplankton that plays a major role in the global carbon...

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...

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...
