Welcome aboard Volcano air-lies: Volcanic ash air chaos to return within days because of wind direction changes

Air chaos from volcanic ash may return within days because of wind direction changes, weather forecasters and aviation chiefs warned last night.

The warning came just hours after all UK and Irish airspace re-opened yesterday following two days of disruption centred on Scotland, Ireland and the North of England.

It also came as the Icelandic volcano at the heart of the problem yesterday increased the amount of ash it is belching out.

'Massive' ash cloud closing western Irish airports

The Moderate Resolution Imaging Spectroradiometer instrument known as MODIS that flies onboard Terra, captured a visible image of the ash plume. The plume was blowing east then southeast over the Northern Atlantic. The satellite image shows that the plume is at a lower level in the atmosphere than the clouds that lie to its east, as the brown plume appears to slide underneath the white clouds.
Dublin - Iceland's volcano has produced a 1,000-mile-wide (1,600 kilometer-wide) ash cloud off the west coast of Ireland that will force western Irish airports to shut down again Friday, the Irish Aviation Authority announced.

The authority said shifting winds, currently coming from the north, had bundled recent days' erupted ash into a massive cloud that is growing both in width and height by the hour.

Eurocontrol, which determines the air routes that airliners can use in and around Europe, says the ash accumulation is posing a new navigational obstacle - because the cloud is gradually climbing to 35,000 feet (10.5 kilometers) and into the typical cruising altitude of trans-Atlantic aircraft. Until recent days, the ash had remained below 20,000 feet (6 kilometers).

The Irish Aviation Authority said the engine-wrecking ash would skirt Ireland's western shores Friday, forcing a half-dozen airports to ground flights for much of the day. However, the airports in Dublin, Cork in the southwest and Waterford in the southeast will remain open.

"The restrictions are required as the increased level of recent volcanic activity has created a massive ash cloud stretching 1,000 miles long and 700 miles wide," the authority said in a statement.

US: Several Tennessee rivers set records

Nashville - A U.S. Geological Survey study shows many rivers in middle Tennessee set high flow records due to heavy rainfall last weekend.

Preliminary estimates released Thursday show the highest stream flows were observed from Nashville west toward Jackson, extending about 40-miles north and south of Interstate 40 and affecting major tributaries of the Cumberland and Tennessee Rivers.

Flows on the Harpeth River exceeded 46,000 cubic feet per second May 3, while the Duck River near Hurricane Mills flowed at 138,000 cfs May 4, exceeding the previous high by 17,000 cfs, the USGS said.

Flood peaks on the Harpeth near Bellevue, Piney River at Vernon, and Duck River at Hurricane Mills appear to have exceeded levels expected with only a 0.2 percent probability (1 in 500 chance) in any given year.

Gulf of Mexico oil slick: amount gushing from well 'could increase 12 fold'

The amount of oil gushing from BP's ruptured oil well in the Gulf of Mexico could increase twelve fold under a worse case scenario, executives from the company told the US Congress.

The well is currently spewing 5,000 barrels a day, or about 210,000 gallons, but that figure could reach 60,000 barrels a day, equivalent to 2.5 million gallons a day, if efforts to stop the leaks fail.

The figure was given in a briefing by executives from BP and Transocean, which owned the sunken Deepwater Horizon rig, to the Congress House Energy and Commerce Committee.

Ed Markey, a Democrat Congressman from Massachusetts on the committee, said they were told the worst case scenario could see the level of oil rise to 40,000 barrels, or even 60,000 barrels a day.

Iran offers to help contain US oil spill

The National Iranian Drilling Company (NIDC) has offered to assist the US in efforts to prevent an ecological disaster caused by the spreading oil spill in the Gulf of Mexico.

Following an explosion on a BP-operated oil rig in the Gulf of Mexico last month, at least 210,000 gallons (5,000 barrels) of crude oil are thought to be spilling into the water every day.

NIDC managing director Heidar Bahmani announced the firm's readiness to use its decades-long expertise to fight the oil slick, the company's public relations office told Press TV.

"Our oil industry experts in the field of drilling can contain the rig leakage in the Gulf of Mexico and prevent an ecological disaster in that part of the world," Bahmani said.

Oil Spill: BP Prepares to Place Dome Over the Leak, But Spill Continues

As the wrecked wellhead at the bottom of the Gulf of Mexico continued to spew oil into the water for a 16th day, BP moved forward with a plan to cap the leak and, it hoped, stop the ecological and economic disaster.

BP said that it would have a giant, 100-ton dome-like device placed over the wellhead Thursday, which could begin to collect oil as soon as next Monday. Before that can happen, the dome will have to be connected to a drill ship that can collect the polluted water and oil.

Under the Wrong Conditions, Oil Spills are Forever

"A senior BP executive conceded Tuesday that the ruptured oil well in the Gulf of Mexico could conceivably spill as much as 60,000 barrels a day of oil, more than 10 times the estimate of the current flow," reports The New York Times today, about a closed-door briefing for members of Congress.

As oil gushes from the Gulf sea bottom, it's interesting to ponder what past spills have done to ecosystems. Under the right - or, better said, the wrong - conditions, oil can linger for decades and longer, causing permanent damage. How is Prince William Sound, site of the Exxon Valdez disaster, doing these days?

From MSNBC:
Twenty years after the Exxon Valdez spilled 11 million gallons of crude oil in Alaska's Prince William Sound, oil persists in the region and, in some places, "is nearly as toxic as it was the first few weeks after the spill," according to the council overseeing restoration efforts.

"This Exxon Valdez oil is decreasing at a rate of 0-4 percent per year," the Exxon Valdez Oil Spill Trustee Council stated in a report marking Tuesday's 20th anniversary of the worst oil spill in U.S. waters. "At this rate, the remaining oil will take decades and possibly centuries to disappear entirely."

... Moreover, surveys "have documented lingering oil also on the Kenai Peninsula and the Katmai coast, over 450 miles away," according to the council.

None of that was expected "at the time of the spill or even ten years later," it added. "In 1999, beaches in the sound appeared clean on the surface. Some subsurface oil had been reported in a few places, but it was expected to decrease over time and most importantly, to have lost its toxicity due to weathering. A few species were not recovering at the expected rate in some areas, but continuing exposure to oil was not suspected as the primary cause."

It turns out that oil often got trapped in semi-enclosed bays for weeks, going up and down with the tide and some of it being pulled down into the sediment below the seabed.

The most kick-ass fish in the sea

If you were looking for an animal to take the title of "most kick-ass fish in the sea", then the tiger puffer would have to be a strong contender.

Not only is it lethally poisonous - though that doesn't stop people trying to eat it - and able to scare off predators by inflating itself to become much larger than normal, when it is young it munches on its own brothers and sisters.

Tiger puffers attach their eggs to rocks near the bottom of the sea, often at the mouths of bays. The larvae hatch, then move to estuaries or mudflats once they have grown a little. Having put on a lot more weight, they head out to sea.

It's no innocent childhood for the pufferfish, though, as Shin Oikawa of Kyushu University in Fukuoka, Japan, and colleagues found when they hatched tiger puffer larvae in the lab and monitored them for two months.
