Scientists Track Down Source of Earth's Hum

You can't hear it, but the Earth is constantly humming. And some parts of the world sing louder than others.

After discovering the mysterious low-frequency buzz in 1998, scientists figured out that the Earth's hum is caused not by earthquakes or atmospheric turbulence, but by ocean waves colliding with the seafloor. Now, researchers have pinpointed the source of the Earth's "background noise," and it looks like it's coming primarily from the Pacific coast of North America.

When two waves of opposite direction but similar frequency collide, they create a special kind of pressure wave that carries energy to the ocean bottom. As these waves pound against the sea floor, they generate a constant vibration with a frequency of about 10 millihertz, much too low for humans to hear but easily detectable with seismometers. By comparing the intensity of the hum with the height of waves around the world, scientists can track where the buzz is coming from.

It is estimated that more than 200 dead starlings were found in downtown Yankton Monday. However, it is not believed the deaths pose a threat to humans.

Yankton Animal Control Officer Lisa Brasel estimated that she collected 200 starlings Monday, and employees of the city Parks and Recreation Department were also on the scene picking up deceased birds. The total number of corpses gathered up by city employees has not yet been compiled.

"I talked to one of the local vets, and they said there is nothing wrong (with the birds)," said Brasel, who took specimens to a veterinary office. "They just didn't migrate and are dying. I was going to call the South Dakota Department of Health to see what they have to say about it, but they are closed today (because of Martin Luther King Day)."

Birdless bird sanctuary in North Holland

I took this amazing video a couple of days ago, this is a bird sanctuary in North Holland but look closely, this area should be teeming with birds but its deserted!

I drive past this sanctuary frequently and it is always full of birds, where did they go?

Hundreds of birds died in Romania, for the second time in a month

Hundreds of dead or agonizing crows have brought terror to a town in the Eastern part of Romania. Since Saturday, the locals of Roman, a town of 80.000 people, have noticed that hundreds of crows fell to the ground dead or in agony in one of the local parks. On Monday, dozens of birds were struggling with death, unable to fly. Local experts suspect that the crows may have been poisoned, but no verdict can be given before a forensic study is conducted.

Some three dozens starlings have also been found dead in Constanţa, by the Black Sea, in Romania, on January the 8th. Veterinarians concluded that the starlings died of cold and alcohol intoxication.

US: Pelicans turn up sick, dead off Jacksonville coast

Hundreds of Eastern brown pelicans, some with missing wings and frostbite, have been injured or killed in the St. Johns River the past couple of weeks in the Mayport area.

The exact reason is unknown but the cold weather could have caused hypothermia when the birds landed in the water. The pelicans have been losing a protective coating they have on their body to shield their feathers from becoming saturated by water.

Cindy Mosling, co-founder of the Bird Emergency Aid and Kare Sanctuary on Big Talbot Island, thinks chemicals in the water could be the culprit.

Canada: Mysterious infection is killing British Columbia salmon

Carleton Professor Part of Team Investigating Mysterious Fish Infection

Ottawa - The Globe and Mail published the following story. Carleton Professor Steven Cooke was one of the 15 scientists involved in this research. He developed the biopsy technique that enabled the collection of non-lethal tissue samples from fish. His lab was involved with fish tagging and tissue collection in the wild.

Mysterious infection is killing B.C. salmon

By Mark Hume

Large numbers of sockeye salmon are dying in the Fraser River, before spawning, because of a mysterious virus, new research suggests.

Historical records show that some fish always die en route to their spawning beds, but since the early 1990s the problem has become increasingly acute - with more than two million fish dying in some years. Researchers have long puzzled over what was causing the seemingly healthy fish to suddenly stop swimming and turn belly up.

A large team of researchers from the federal Department of Fisheries and Oceans and three Canadian universities has now found most of the fish that die before spawning have a common "genomic signature" - or a pattern that shows changes have taken place in an array of genes activated to fight infection.

"Our hypothesis is that the genomic signal associated with elevated mortality is in response to a virus infecting fish before river entry and that persists to the spawning areas," says the report published in the journal Science on Thursday.

New Zealand: Mourning Dolphin Carries Dead Calf Around Harbour

A female dolphin carrying a dead calf has been spotted swimming in Whangarei Harbour.

Northland orca researcher and whale expert Ingrid Visser was on the water last Thursday and managed to take photos of the female dolphin, known as Potato, with the dead calf.

"The dead baby was very decomposed, most bones gone, blubber floating at the surface when she stopped carrying it, for moments only. She was carrying it on her dorsal fin, across her pectoral fins and across her tail flukes," Dr Visser said.

The dolphin managed to travel up to 8 knots and went to the bow of Dr Visser's boat at one stage.

"There is concern for her in terms of the decomposition of the carcass - having it near her eyes, mouth and blowhole when it is full of bacteria is not a good option."

Dr Visser said they could only get close during the two hours they tracked the dolphin.

Brazil Landslide and Flood Toll Reaches 665

The death toll from flooding and mudslides in southeastern Brazil climbed to at least 665 people, as public outcry turned toward authorities' ongoing struggle to reach still-isolated areas and their failure last week to have warned residents of the danger of gathering storms.

Relief workers continued to unearth victims on Monday, even as rescue crews managed to reach survivors who have been trapped by earth and floodwaters since the downpours hit the state of Rio de Janeiro almost a week ago. In addition to those killed, nearly 14,000 people have been displaced from destroyed or damaged homes. An unknown number of people remain missing.

Amid the relief and recovery efforts, Brazilians are increasingly expressing outrage at local, state, and federal officials.

In addition to criticism that authorities had turned a blind eye toward construction in areas known to be vulnerable to flooding, they are now asking why the government, despite modern weather and communications systems, were unable to alert victims of the pending danger. Southern Brazil, after all, has been subject to frequent flooding in recent years, including downpours and landslides that killed hundreds of people during last year's rainy season.

100,000 homes flattened or damaged by storms

Beijing - Rescue workers evacuated thousands of rural residents from parts of northwestern China after extreme cold and blizzard conditions killed four people and left half a million snowed under, meteorologists said Monday.

In neighboring Mongolia, an official appealed for help from the international community as his country battles the most severe winter it has seen in three decades.

Storms in China's far western Xinjiang flattened or damaged about 100,000 homes and more than 15,000 head of livestock were killed by the cold front that set in Sunday night.

Herders moved thousands of others to safer pastures at lower altitudes ahead of the latest storm front, which is expected to last through Wednesday.

Scientists warn California could be struck by winter 'superstorm'

A group of more than 100 scientists and experts say in a new report that California faces the risk of a massive "superstorm" that could flood a quarter of the state's homes and cause $300 billion to $400 billion in damage. Researchers point out that the potential scale of destruction in this storm scenario is four or five times the amount of damage that could be wrought by a major earthquake.

It sounds like the plot of an apocalyptic action movie, but scientists with the U.S. Geological Survey warned federal and state emergency officials that California's geological history shows such "superstorms" have happened in the past, and should be added to the long list of natural disasters to worry about in the Golden State.

The threat of a cataclysmic California storm has been dormant for the past 150 years. Geological Survey director Marcia K. McNutt told the New York Times that a 300-mile stretch of the Central Valley was inundated from 1861-62. The floods were so bad that the state capital had to be moved to San Francisco, and Governor Leland Stanford had to take a rowboat to his own inauguration, the report notes. Even larger storms happened in past centuries, over the dates 212, 440, 603, 1029, 1418, and 1605, according to geological evidence.

Comment: Is there a possibility these scientists are wrong in their view of the atmosphere warming? Perhaps the atmosphere is cooling while the planet itself is warming?
