Past regional cold and warm periods linked to natural climate drivers
Intervals of regional warmth and cold in the past are linked to the El Niño phenomenon and the so-called "North Atlantic Oscillation" in the Northern hemisphere's jet stream, according to a team of climate scientists. These linkages may be important in assessing the regional effects of future climate change. view more (2009-11-30)
Galician waves are best for producing energy
The best coastal areas in the Iberian Peninsula in terms of harnessing wave energy are the Costa da Morte and Estaca de Bares, in La Coruña, Galicia, according to two pioneering studies by researchers from the University of Santiago de Compostela (USC), published this month in the journals Energy and Renewable Energy. view more (2009-11-30)
Robotic clam digs in mudflats
To design a lightweight anchor that can dig itself in to hold small underwater submersibles, Anette (Peko) Hosoi of MIT borrowed techniques from one of nature's best diggers -- the razor clam. view more (2009-11-23)
Active hearing process in mosquitoes
A mathematical model has explained some of the remarkable features of mosquito hearing. In particular, the male can hear the faintest beats of the female's wings and yet is not deafened by loud noises. view more (2009-11-20)
Climate variability and dengue incidence
Research published this week in PLoS Medicine demonstrates associations between local rainfall and temperature and cases of dengue fever, which affects an estimated fifty million people per year worldwide. view more (2009-11-16)
Ida now a coastal low assaulting the Mid-Atlantic
Ida is one stubborn girl. Her remnants have moved out to sea and reformed as a powerful coastal low pressure system that's been raining on the mid-Atlantic since Tuesday night, November 10. view more (2009-11-13)
Vibrations key to efficiency of green fluorescent protein
University of California, Berkeley, chemists have discovered the secret to the success of a jellyfish protein whose green glow has made it the darling of biologists and the subject of the 2008 Nobel Prize in Physiology or Medicine. view more (2009-11-12)
Anisakiasis hazard varies depending on the origin of the fish, according to a study
A research team of the University of Granada (Spain) has confirmed a higher presence of the parasite Anisakis spp in anchovies of the Atlantic South East coast and the Mediterranean North West coast, and they insist on freezing or cooking fish before consuming it. view more (2009-11-11)
Iron controls patterns of nitrogen fixation in the Atlantic
Scientists including researchers from the National Oceanography Centre, Southampton and the University of Essex have discovered that interactions between iron supply, transported through the atmosphere from deserts, and large-scale oceanic circulation control the availability of a crucial nutrient, nitrogen, in the Atlantic. view more (2009-11-03)
North Atlantic Fish Populations Shifting as Ocean Temperatures Warm
About half of 36 fish stocks in the Northwest Atlantic Ocean, many of them commercially valuable species, have been shifting northward over the last four decades, with some stocks nearly disappearing from U.S. waters as they move farther offshore, according to a new study by NOAA researchers. view more (2009-11-03)
Contracts foster trust, but flexibility is needed, research says
While detailed contracts can foster trust between parties, there needs to be flexibility in negotiating potential changes, according to research recently published in MIS Quarterly. view more (2009-11-02)
North Carolina sea levels rising 3 times faster than in previous 500 years, Penn study says
An international team of environmental scientists led by the University of Pennsylvania has shown that sea-level rise, at least in North Carolina, is accelerating. view more (2009-10-29)
Volcanoes played pivotal role in ancient ice age, mass extinction
Researchers here have discovered the pivotal role that volcanoes played in a deadly ice age 450 million years ago. Perhaps ironically, these volcanoes first caused global warming -- by releasing massive amounts of carbon dioxide into the atmosphere. When they stopped erupting, Earth's climate was thrown off balance, and the ice age began. view more (2009-10-27)
Seismic Noise Unearths Lost Hurricanes
Seismologists have found a new way to piece together the history of hurricanes in the North Atlantic - by looking back through records of the planet's seismic noise. It's an entirely new way to tap into the rich trove of seismic records, and the strategy might help establish a link between global warming and the frequency or intensity of... view more...

Whale-sized genetic study largest ever for southern hemisphere humpbacks
After 15 years of research in the waters of the South Atlantic and Indian Oceans, scientists from the Wildlife Conservation Society, the American Museum of Natural History, and an international coalition of organizations have unveiled the largest genetic study of humpback whale populations ever conducted in the Southern Hemisphere. view more (2009-10-14)
NASA satellite reveals a depressed and disorganized Henri
Depression happens to everyone, even tropical storms, and Henri is now tropically depressed. NASA satellite imagery has confirmed he's weakened to a tropical depression and he is further expected to degenerate into a remnant low pressure area. view more (2009-10-09)
Henri born in Eastern Atlantic... could be short-lived
Forecasters were watching a storm they designated as 91 yesterday, October 6, until it organized into a tropical cyclone east of the Leeward Islands around 5 p.m. EDT. It was then named "Tropical Storm Henri," the eighth named tropical cyclone of the Atlantic hurricane season. view more (2009-10-08)
Panama butterfly migrations linked to El Niño, climate change
A high-speed chase across the Panama Canal in a Boston Whaler may sound like the beginning of another James Bond film-but the protagonist of this story brandishes a butterfly net and studies the effects of climate change on insect migrations at the Smithsonian Tropical Research Institute. view more (2009-10-06)
A sudden Tropical Storm Grace explodes in far Eastern Atlantic
The latest tropical storm in the Atlantic Ocean may have escaped the notice of most when it formed just before midnight last night so far north and east in the Atlantic, away from where forecasters usually look for forming storms. view more (2009-10-06)
Joint U.S. - Norwegian Study Provides New Insights into Marine Ecosystems and Fisheries Production
NOAA and Norwegian researchers recently completed a comparative analysis of marine ecosystems in the North Atlantic and North Pacific to see what factors support fisheries production, leading to new insights that could improve fishery management plans and the ecosystems. view more (2009-10-01)
