For a few years now the world has been aware of the poisoning of our oceans with plastic. The image of spiral-shaped debris island in Pacific off the Californian coast, called Great Pacific Garbage Patch, is a haunting one as is the image of decomposing dead birds whose bodies have become plastic dumpsters.

Mitt Romney continues to shock the environmental community with his extremely clear and forceful contempt for the ecological issues facing us all. His language couldn’t have been any more distinct in his interview on “Meet the Press” yesterday, during which he told NBC’s David Gregory, “I’m not in this race to slow the rise of the oceans or to heal the planet. I’m in this race to (more…)
A new study published in the journal Science suggests that the cycle of evaporation and rainfall over the world’s oceans has accelerated 4 percent in the last half-century as a result of global warming, a development that could portend more extreme weather in the decades to come. (more…)
Plastiki started its journey March 20 from San Francisco, with the intention to create public awareness about the effects of plastic usage on marine pollution and consequently sea life.
The Plastiki crew aims to explore a number of environmental hotspots, such as soon-to-be-flooded island nations, damaged coral reefs and the challenge faced by acidifying oceans and marine debris, in particular plastic pollution.
Plastiki’s journey is also scheduled to go through the Great Pacific Garbage Patch, a zone of trash one suspended on the water’s surface, twice the size of Texas, and stretching from the shores of California to the Sea of Japan.
The boat crew consists of six scientists, environmentalists and artists, led by the British adventurer David de Rothschild. The 60-foot boat is sailing with an average speed of five nautical miles per hour and the voyage is set end in Sydney in about three months. (more…)
Hot, nutrient-rich water seeping from a network of deep-sea volcanoes provides a consistent source of iron for the phytoplankton that soaks up carbon dioxide, playing a key role in limiting climate change, according to a new study by French and Australian scientists.
The world’s oceans capture about 25 percent of the carbon dioxide emitted by human activities, including the burning of fossil fuels, scientists say. Among the largest “carbon sinks” is the Southern Ocean between Antarctica and Australia.
Underpinning that cycle is the microscopic plant phytoplankton, which absorbs the carbon dioxide at the ocean surface and then eventually carries it to the ocean floor.
While it is well known that iron carried in dust or in coastal sediments can trigger phytoplankton blooms, the extent and consistency of deep-sea vents as a source of nutrients was not as well understood, according to the study published in the journal Nature Geoscience. (more…)
