Efficient Hemoglobin Key To Fish Success
2013-06-17 12:26:31

Brett Smith for redOrbit.com - Your Universe Online The primordial oceans in Earth´s early days were a much more inhospitable than they are today, and new research published in the journal Science suggests that fish developed a highly efficient hemoglobin-based system to deliver large amount of oxygen to their tissues. “Four hundred million years ago the oceans were not what they are today. They were low in oxygen, high in CO2 and acidic,” said study co-author Jodie...

Purple Urchins Quickly Adapt To Acidic Oceans
2013-06-13 11:41:25

Brett Smith for redOrbit.com - Your Universe Online As the levels of atmospheric carbon dioxide increase, the oceans are projected to absorb more of the greenhouse gas, leading to acidification of the water. This shift in oceanic chemistry is expected to negatively impact countless species. However, a new study from the University of California, Santa Barbara has found that purple sea urchins Strongylocentrotus purpuratus are capable of evolving in a way that copes with potential...

Lawrence Livermore National Laboratory researchers have broken the record for tracking the movement and concentration of carbon dioxide in a geologic formation using the world's deepest Electrical Resistance Tomography (ERT) system. The research provides insight into the effects of geological sequestration to mitigate the impact of greenhouse gases. The team led by LLNL's Charles Carrigan obtained time lapse electrical resistivity images during the injection of more than 1 million tons...

Mixed News For Pacific Northwest Oyster Industry In World Oceans Month
2013-06-13 10:38:01

National Science Foundation Ocean acidification inhibits shell formation, but interventions at hatcheries may offset some effects, scientists find For the past several years, it has struggled with significant losses due to ocean acidification. Oyster larvae have had mortality rates high enough to render production no longer economically feasible. Now a new study documents why oysters appear so sensitive to increasing acidity, but also offers some hope for the future. It isn't...

Rich Rosenberg, Veteran ExxonMobil Executive, and Andrew Lee, Upstream Expert, Join Summit Team SEATTLE, June 12, 2013 /PRNewswire/ -- Summit Power Group, a leading developer of renewable power and low-carbon energy projects, announced today that Rich Rosenberg and Andrew Lee have accepted executive positions in the company's business unit focusing on carbon capture and emerging clean energy technologies. Mr. Rosenberg has joined Summit as the Director of Strategic Relationships and...

Carbon Found To Leak From Land To Water
2013-06-11 09:35:26

April Flowers for redOrbit.com - Your Universe Online In general, scientists have thought that about half of the carbon emitted by human activities remains in the atmosphere, with the other half being stored in the oceans and on land. A new study, published in Nature Geoscience, suggests that human activity might be increasing the transition of carbon from land to rivers, estuaries and the coastal zones. This indicates that large quantities of anthropogenic carbon might be hidden in...

WASHINGTON, June 10, 2013 /PRNewswire-USNewswire/ -- The chief economist at the International Energy Agency sees catastrophic consequences for the planet if governments fail to take more immediate and decisive action to combat global warming. Fatih Birol, one of the world's most respected energy experts, told the Guardian newspaper that greenhouse gas emissions were continuing to rise so fast that waiting much longer to replace the Kyoto protocol would set the earth on a path to 5C of...

OTTAWA, June 7, 2013 /CNW/ - Canada Post's 2012 Social Responsibility report showed a 12-per-cent decrease in injury frequency from the previous year, marking the Corporation's best safety performance in nearly 30 years. The total number of lost-time injuries also decreased in 2012, by 11 per cent from 2011. The report details Canada Post's social and environmental performance for 2012, including safety, employee relations, carbon emissions and community programs. The release...

3 billion-year-old Rocks Contain Microfossils Of Plankton
2013-06-06 21:18:25

Penn State Spindle-shaped inclusions in 3 billion-year-old rocks are microfossils of plankton that probably inhabited the oceans around the globe during that time, according to an international team of researchers. "It is surprising to have large, potentially complex fossils that far back," said Christopher H. House, professor of geosciences, Penn State, and lead author. However, the researchers not only showed that these inclusions in the rocks were biological in origin, but also...

Improving Ventilation In Schools Could Reduce Illness-Related Absences
2013-06-06 07:47:49

redOrbit staff & Wire Reports — Your Universe Online Making sure that students get enough fresh air in their classrooms could keep kids from missing school due to illness, researchers from the at Lawrence Berkeley National Laboratory (Berkeley Lab) claim in a new study. Writing in the journal Indoor Air, lead author Mark Mendell and his colleagues report that their analysis of over 150 California classrooms revealed that bringing classroom ventilation rates up to state...

Aquascaping
2013-04-02 10:31:02

Aquascaping is the art of arranging aquatic plants along with rocks, cavework, stones, or driftwood, in an aesthetically pleasing manner within an aquarium. Aquascape designs incorporate numerous distinctive styles. Usually, an aquascape houses fish as well as plants, although it’s possible to produce an aquascape with solely plants, or with rockwork or other hardscape and no plants. Even though the main goal of aquascaping is to construct an artful underwater landscape, the technical...

Ocean Acidification
2013-04-01 10:32:20

Ocean acidification is the name that was given to the ongoing decrease in the pH of Earth’s oceans, a cause of the uptake of anthropogenic carbon dioxide from the atmosphere. About 30 to 40 percent of the carbon dioxide that is released by humans into the atmosphere dissolves into the lakes, oceans, and rivers. To maintain the chemical equilibrium, some of it reacts with the water to create carbonic acid. Some of these extra carbonic acid molecules react with a water molecule to provide a...

Earth's Atmosphere
2004-10-19 04:45:44

Earth's Atmosphere -- Earth's atmosphere consists of nitrogen (78.1%) and oxygen (20.9%), with small amounts of argon (0.9%), carbon dioxide (variable, but around 0.035%), water vapor, and other gases. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. 75% of the atmosphere exists within 11km of the planetary surface. Temperature and the Atmospheric Layers The temperature of the Earth's atmosphere...
