Decline in uptake of carbon emissions confirmed
A decline in the proportion of carbon dioxide (CO2) emissions absorbed by land and oceans is speeding up the growth of atmospheric CO2, according to a paper published today in the US Journal: Proceedings of the National Academy of Science.   view more (2007-10-25)

Meteor no longer prime suspect in great extinction
The greatest mass extinction in Earth's history also may have been one of the slowest, according to a study that casts further doubt on the extinction-by-meteor theory.   view more (2007-10-25)

New light trap captures larval stage of new species; DNA barcode technology used
When David Jones, a fisheries oceanographer at the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) located at the University of Miami's Rosenstiel School, set out to design a better light trap to collect young reef fishes, he never imagined his invention would contribute to the... view more (2007-10-24)

Unexpected growth in atmospheric CO2
A team of scientists has found that atmospheric carbon dioxide (CO2) growth has increased 35 percent faster than expected since 2000. The findings are published this week in the journal Proceedings of the National Academy of Sciences (PNAS).   view more (2007-10-23)

North Atlantic slows on the uptake of CO2
Further evidence for the decline of the oceans' historical role as an important sink for atmospheric carbon dioxide is supplied by new research by environmental scientists from the University of East Anglia.   view more (2007-10-23)

Rise in atmospheric CO2 accelerates as economy grows, natural carbon sinks weaken
Human activities are releasing carbon dioxide faster than ever, while the natural processes that normally slow its build up in the atmosphere appear to be weakening.   view more (2007-10-23)

Successful Ariane 5 upper stage engine re-ignition experiment
A successful re-ignition of the Ariane 5 upper stage engine performed during the most recent mission has consolidated Ariane 5's readiness for the launch of the Jules Verne Automated Transfer Vehicle.   view more (2007-10-23)

Research shows loggerhead sea turtles threatened by small-scale fishing operations
Washington, DC. Ocean Conservancy Scientist, Wallace J. Nichols and University of California-Santa Cruz researcher Hoyt Peckham found surprising results in a recent peer-reviewed loggerhead sea turtle study that Nichols and Peckham conducted over the course of 10 years. The full study will be... view more (2007-10-17)

Arctic sea ice shatters record low: diminished ice leads to Northwest Passage opening
Arctic sea ice during the 2007 melt season plummeted to the lowest levels since satellite measurements began in 1979, according to researchers at the University of Colorado at Boulder's National Snow and Ice Data Center.   view more (2007-10-02)

Researchers detect hint of oxygen 50 to 100 million years earlier than first believed
Two teams of scientists, including three researchers from UC Riverside, report that traces of oxygen appeared in Earth's atmosphere roughly 100 million years before the "Great Oxidation Event" 2.4 billion years ago.   view more (2007-09-28)

Smithsonian scientists working to save microscopic threatened species
The Smithsonian's National Zoo recently acquired 12,000 new animals-microscopic Elkhorn coral larvae harvested by National Zoo scientists in Puerto Rico-as part of an international collaborative program to raise the threatened species.   view more (2007-09-27)

Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
Today, the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) gets underway, with the Japanese drilling vessel Chikyu departing from Shingu Port with scientists aboard, all ready to log, drill, sample, and install monitoring instrumentation in one of the most active earthquake zones on Earth.   view more (2007-09-21)

NASA celebrates a decade observing climate impacts on health of world's oceans
The NASA-managed Sea-viewing Wide Field-of-view Sensor (SeaWiFS) instrument settled into orbit around Earth in 1997 and took its first measurements of ocean color.   view more (2007-09-20)

CO2 emissions could violate EPA ocean-quality standards within decades
In a commentary in the September 25, 2007, issue of the Geophysical Research Letters (GRL), a large team of scientists state that human-induced carbon dioxide (CO2) emissions will alter ocean chemistry to the point where it will violate U.S. Environmental Protection Agency Quality Criteria [1976]... view more (2007-09-20)

Metagenomics of the deep Mediterranean
Metagenomics is a revolutionary approach to study microbes. Rather than isolating pure cultures, the power of high-throughput sequencing is applied directly to environmental samples to obtain information about the genomes of the prokaryotic cells present in a specific habitat studied.   view more (2007-09-19)

The sea-ice is getting thinner - A closer look at the climate and ecosystem of the Arctic Ocean
Large areas of the Arctic sea-ice are only one metre thick this year, equating to an approximate 50 percent thinning as compared to the year 2001.   view more (2007-09-14)

Ancient whale fall from California's Año Nuevo Island one of youngest, most complete known
A fossilized whale skeleton excavated 20 years ago amid the stench and noise of a seabird and elephant seal rookery on California's Año Nuevo Island turns out to be the youngest example on the Pacific coast of a fossil whale fall and the first in California, according to University of... view more (2007-09-14)

Icy calculations on a hot topic
University of Utah mathematicians have arrived at a new understanding of how salt-saturated ocean water flows through sea ice - a discovery that promises to improve forecasts of how global warming will affect polar icepacks.   view more (2007-09-11)

Acid Rain Has a Disproportionate Impact on Coastal Waters
The release of sulfur and nitrogen into the atmosphere by power plants and agricultural activities plays a minor role in making the ocean more acidic on a global scale, but the impact is greatly amplified in the shallower waters of the coastal ocean, according to new research by atmospheric and... view more (2007-09-10)

New faraway sensors warn of emerging hurricane's strength
A new study supported by NASA and the U.S. Office of Naval Research takes forecasters one step further to improving their ability to predict just how powerful an oncoming storm may become by using highly-sensitive sensors located thousands of miles from the storm to detect lightning outbreaks... view more (2007-09-07)

Small-scale parasitic battles may have epic evolutionary proportions
Scientists at MIT's Department of Civil and Environmental Engineering and the Technion Israel Institute of Technology have for the first time recorded the entire genomic expression of both a host bacterium and an infecting virus over the eight-hour course of infection.   view more (2007-09-06)

Migrating squid drove evolution of sonar in whales and dolphins, researchers argue
Behind the sailor's lore of fearsome battles between sperm whale and giant squid lies a deep question of evolution: How did these leviathans develop the underwater sonar needed to chase and catch squid in the inky depths"   view more (2007-09-06)
