Plankton, Base of Ocean Food Web, in Big Decline

Washington - Despite their tiny size, plant plankton found in the world's oceans are crucial to much of life on Earth. They are the foundation of the bountiful marine food web, produce half the world's oxygen and suck up harmful carbon dioxide.

And they are declining sharply.

Worldwide phytoplankton levels are down 40 percent since the 1950s, according to a study published Wednesday in the journal Nature. The likely cause is global warming, which makes it hard for the plant plankton to get vital nutrients, researchers say.

The numbers are both staggering and disturbing, say the Canadian scientists who did the study and a top U.S. government scientist.

Montana, US: Woman Recounts Bear Attack as Caught Grizzly ID'd

One of the survivors of a deadly grizzly bear attack said Thursday she realized her only hope was to play dead after feeling the bear's jaw clamp onto her arm in the middle of the night.

Wildlife officials were testing the DNA of a bear captured at the site of the early Wednesday mauling to confirm it was the animal that also killed a Michigan man and hurt another camper near Yellowstone National Park, but they said they were confident they had caught the right animals.

"Something woke me up, and a split second later, I felt teeth grinding into my arm," Deb Freele of London, Ontario, said from her bed at a Wyoming hospital. "I realized, at that split second, I was being attacked by a bear, but I couldn't see it.

"It was behind me and I screamed. I couldn't help it - it's kind of like somebody else was screaming," she told The Associated Press. "And then it bit me harder, and more. It got very aggressive and started to shake me."

More than 30,000 trapped by floods in China's northeast

More than 30,000 people are thought to be trapped by floodwaters in a town in northeast China, state media said Wednesday, as torrential rain that has killed over 300 in two weeks continues.

China is struggling with its worst flooding in a decade tat has left 1,405 dead or missing since the beginning of the year and caused at least 26 billion dollars in damage, and authorities have warned of more to come.

In the central city of Wuhan, tens of thousands of people have been evacuated as authorities brace for flood crests from the Yangtze River and one of its tributaries to converge there.

More than 200 rescue workers have been sent to northeastern Jilin province's Kouqian town to reach 30,000 residents thought to be trapped after a nearby reservoir overflowed, the official Xinhua news agency said.

The local train station was also surrounded by water with over 80 people trapped inside, it said.

EPA: 1M gallons of oil may be in Michigan river

EPA says 1 million gallons of oil may have spilled in Mich. river, governor criticizes cleanup.

Federal officials now estimate that more than 1 million gallons of oil may have spilled into a major river in southern Michigan, and the governor is sharply criticizing clean-up efforts as "wholly inadequate."

The U.S. Environmental Protection Agency released the update Wednesday night, shortly after Gov. Jennifer Granholm lambasted attempts to contain the oil flowing down the Kalamazoo River. She warned of a "tragedy of historic proportions" if the oil reaches Lake Michigan, which is still at least 80 miles downstream from where oil has been seen.

Granholm called on the federal government for more help, saying resources being marshaled by the EPA and Enbridge Inc., which owns the pipeline that leaked the oil, were "wholly inadequate."

New garbage patch discovered in Indian Ocean

Scientists recently announced the existence of a garbage patch in the Indian Ocean - the third major collection of plastic garbage discovered in the world's oceans. The Great Pacific Garbage Patch, located in the North Pacific Ocean gyre, is well known. And more recently scientists confirmed the existence of a second garbage patch in the North Atlantic gyre.

Marcus Eriksen, cofounder of 5 Gyres Institute, reports that all of the 12 water samples collected in the 3,000 miles between Perth, Australia, and Port Louis, Mauritius (an island due East of Madagascar), contain plastic.

"We did find another large concentration of plastic debris," says the marine scientist who co-founded 5 Gyres Institute with his wife, Anna Cummins, to research plastic pollution in the world's oceans. The team works in collaboration with Algalita Marine Research Foundation and Pangaea Explorations.

Scientists Discover and Image Explosive Deep-Ocean Volcano

Scientists funded by NOAA and the National Science Foundation recorded the deepest erupting volcano yet discovered, describing high-definition video of the undersea eruption as "spectacular." Eruption of the West Mata volcano, discovered in May, occurred nearly 4,000 feet below the surface of the Pacific Ocean, in an area bounded by Fiji, Tonga and Samoa.

Imagery includes large molten lava bubbles approximately three feet across bursting into cold seawater, glowing red vents explosively ejecting lava into the sea, and the first-observed advance of lava flows across the deep-ocean seafloor. Sounds of the explosive eruption were recorded by a hydrophone and later matched to the video footage.

"We found a type of lava never before seen erupting from an active volcano, and for the first time observed molten lava flowing across the deep-ocean seafloor," said the mission's Chief Scientist Joseph Resing, a chemical oceanographer at the University of Washington who collaborates with NOAA through the Joint Institute for the Study of the Atmosphere and Ocean. "Though NOAA and partners discovered a much shallower eruption in 2004 in the Mariana Arc, the deeper we get, the closer the eruption is to those that formed most of the oceanic crust."

Britain "Facing Tarantula Invasion," RSPCA Warns

Britain could be facing a tarantula invasion after a number of the spiders were discovered in gardens in some parts of the country, wildlife experts have warned.

The RSPCA has issued an alert urging people to be on their guard amid fears a large batch of the spider has escaped in the north of the country.

The alert came after two separate incidents involving 10cm-wide Chilean Rose tarantulas in Bolton, Greater Manchester.

The rare arachnids, capable of blinding people by spitting hairs in their eyes, were both found in back gardens within two miles of each other.

Both spiders are the same age, breed and gender.

New Zealand: Snapper Wash Up in Mystery Incident

The Ministry of Fisheries is asking for help from Waiheke residents after hundreds of fish were washed up on one of the island's beaches.

Walkers on Oneroa Beach last Thursday were stunned to discover dead snapper "every couple of steps".

While seagulls enjoyed a five-star feast, an honorary fisheries officer visited the beach to count and check the size of the specimens.

Ministry field operations manager Greg Keys says the incident is under investigation but there are many possible causes.

To rule out one possibility - whether the fish had been poisoned by algae - some of them will be tested for poison.

But Mr Keys says the fish could have escaped from a split net from a commercial fishing boat. Mr Keys says he has heard reports of similar occurrences on the Coromandel.

"It can happen accidentally from split nets or when there are too many fish and they spill over the side of the net, or the fishing boat might dump them."

Meanwhile, Department of Conservation marine ranger Guy Toogood says he understands the fish were too small to have come from a commercial take.
