NASA Maps Growing Marine Dead Zones

NASA has created new maps showing the grim reality of marine dead zones.  These areas of deep water where oxygen levels are too low for marine life to survive have grown at a staggering pace since the middle of the 20th century.

The dead zones are created when fertilizer run off from crops makes it into the ocean, creating massive algae blooms.  When the algae dies, it sinks to us cialis the bottom where microbes decompose the matter, which consumes oxygen and visit our site generic levitra online pharmacy creates a suffocating environment for marine life.

NASA was able to located the areas where this was occurring by using satellites that detect high concentrations of particulate organic matter.  Those high concentrations are a signal of extra fertile areas that lead to dead zones.

The dead zones are mainly located along the coasts of large population centers, with the east coast of the U.S. and the coasts of Northern Europe having the largest numbers of these zones.

Since the 1960's, the creation of dead zones has snowballed, with the total amount of click here cialis soft gel area occupied by dead zones now equaling 152,000 square miles and 400 different ecosystems being affected.

Increased CO2 Causes Clownfish to Lose Sense of Smell, Swim Toward Predators

Climate change is we use it viagra non prescription having a dramatic affect on buying viagra without prescription the oceans -- rising sea levels, warming temperatures, increased acidity -- all of which will take its toll on sea life.  The clownfish will have a particularly hard time surviving, as scientists have discovered that rising CO2 levels in the oceans alter their sense of smell, preventing them from evading predators and finding shelter.

Researchers at James Cook University simulated CO2 levels within the range predicted for the end of the century with clownfish larvae.  The experiments tested their behavior at increasing concentrations.   At 550 ppm of CO2, the current concentration, larvae were able to detect a predator and swim in the opposite direction, but as the concentrations rose to 700 ppm, only half the discount viagra online larvae swam away, with the other half swimming toward a predator.

At the highest concentration, 850 ppm, their sense of smell was completely askew and all larvae swam toward the predator.

The same researchers carried out experiments last year that showed that rising CO2 levels also prevented baby clownfish from being able to find their way home.

The researchers think that the CO2 could be affecting the fishes' neurons and confusing how they perceive threats and interpret smells and that other fish will likely be similarly affected.

Antarctica Getting Its Own Garbage Patch

Massive concentrations of garbage have been discovered where ocean currents meet.  The Great Pacific garbage patch, the largest of them all, has inspired a team to sail a boat made out of recommended site buy cialis in new zealand recycled plastic to bring attention to i recommend woman and cialis the giant problem.  Others have been discovered in the Atlantic Ocean and elsewhere around the world and the latest news is that one could be forming in Antarctica.

Ocean surveys conducted by British scientists in the austral summer of 2007-2008 found plastic debris floating on the surface even in the remote areas of the Davis, Durmont D'Urville and Amundsen Seas.  Luckily, dragging of the seabed found it to be clean.  The researchers think the garbage is the farthest reach of a tide of plastic that will most likely keep growing.

The picture above shows all known ocean garbage patches.

Weather Notes from Both Poles


Indicators continue to show disturbing trends and unexpected events, indicating that changes are taking place in the Earth's environment. The South Pole has had its warmest year ever (since recordkeeping began in the 1950s), and the North Pole experienced unexpected rain in late April.

"My business is weird, wild and wacky weather, and this is up there among fish falling from the very good site buy viagra now sky or Niagara Falls running dry," according to David Phillips, a senior climatologist with Environment Canada. "I mean, it really is strange. You just don't expect it to rain in the High Arctic in April; maybe in July and August."

Phillips also indicated that over 50 years of historical weather data show "no signs of rainfall ever occurring in April in the High Arctic." The unusual rain could be an indicator of further shifts beginning to take place in Arctic weather patterns due to the continuing warming of the region.

The Amundsen-Scott South Pole Station recorded the highest average annual temperature in 2009. It was also the second warmest year on record for overall surface temperatures on the Earth, according to NASA.

IBM Requiring Suppliers to Track and Report Environmental Data

IBM has made a significant step in cleaning up its global operations.  It's now requiring all of its suppliers in 90 different countries to cialis 10mg install management systems to track environmental data like energy use, greenhouse gas emissions, and waste and recycling levels.  All suppliers must set environmental goals and publicly report their progress.

For large global companies like IBM, turning over a greener leaf starts with gathering environmental data on all parts of your supply chain.  Once armed with that information, IBM will know where and how to make changes.

IBM is also requiring any subcontractors of their suppliers to track the same data if they're a significant part of the supply chain.  The company says their goal with this project is to systemize environmental management and sustainability so that all of its global partners are working with the same type of information and are easily able to set and reach environmental goals.

All suppliers will need to have these systems installed by early 2011.  If they don't comply, IBM says it will no longer do levitra online no prescription business with them.
