The federal government confirmed Tuesday that subsea clouds of dispersed oil have been found at least 40 miles from the site of the Deepwater Horizon oil leak in the Gulf of Mexico. The finding, which confirms what some independent scientists first reported last month, has renewed concerns over the effects of the oil spill on deep-sea life. 
"NOAA is confirming the presence of very low concentrations of subsurface oil down to 3300 meters, 42 miles north of wellhead," NOAA administrator Jane Lubchenco said in a news conference.




 
BP reported this morning that on Monday it captured approximately 14,800 barrels of oil from the broken well in the Gulf of Mexico, where crude has been flowing since the Deepwater Horizon rig sank on April 22.
As we've done since BP began capturing oil from the well, we've updated our Gulf Leak Meter to reflect that new figure. We've also decided to update the minimum leak rate on our meter.
On May 27, a government panel said the flow rate was at least 12,000 to 19,000 barrels of oil per day. We adjusted the ticker then, using 12,000 as our new minimum. That figure is clearly too low, since BP can't capture more oil than is leaking, so we've set the minimum possible leak rate to the next available rate, 19,000 barrels (798,000 gallons) per day.

The Puerto Rico earthquake of May 16, 2010, occurred in an inclined seismic zone that dips south from the Puerto Rico Trench and that consists of subducted lithosphere of the North America plate. The broad-scale tectonics of the Puerto Rico region are determined by the motion of the Caribbean plate east-northeast at a velocity of about 20 mm/yr with respect to the North America plate. The North America plate is thrust beneath the Caribbean plate at the Puerto Rico Trench, and is seismically active to depths of about 150 km.
Earthquakes, such as this one, that have focal-depths between 70 and 300 km are commonly termed "intermediate-depth" earthquakes. Intermediate-depth earthquakes typically cause less damage on the ground surface above their foci than is the case with similar magnitude shallow-focus earthquakes, but large intermediate-depth earthquakes may be felt at great distance from their epicenters.

Dust Over Sydney

Posted by wyneman under
Sept. 23 source  (Bloomberg) -- An orange glow blanketed Sydney today as gale-force winds whipped up one of the city’s largest dust storms on record, shrouding the Opera House with a choking powder, snarling traffic and forcing airlines to divert flights.
“It’s like a nuclear winter morning,” Peter Wilson, 53, a visitor from Queensland state, said at Circular Quay in central Sydney as fog horns echoed across the harbor. “It is so eerie.”

The Harbor Bridge was hidden by a thick haze as the early morning sun struggled to pierce the blanket of dust blown in from the dry interior of the continent. Train commuters, some wearing masks or clutching handkerchiefs to avoid breathing in the dust, stood on the platform snapping photographs of the spectacle on their mobile phones.
The Bureau of Meteorology issued a severe weather warning for wind gusts as fast as 90 kilometers (56 miles) an hour, while the New South Wales state government said air quality in parts of the city was “hazardous.”

Schools were advised to keep pupils indoors and keep a close eye on students with asthma, the New South Wales state Education Department said. Sports lessons were canceled.
Ferry services on the harbor resumed after being suspended and high winds and low visibility disrupted flights at Sydney airport, with some aircraft diverted to Melbourne and Brisbane.

“I haven’t seen dust storms like this since I was in China a few years ago,” said solicitor Jim Harrowell, 55, as he stood in the financial district, where office windows were clogged with dust. “We’re lucky it’s not raining, otherwise there would be little red spots all over us.”
Dirty Yachts
Yachts on the harbor, usually gleaming white, had a dull yellowy sheen. Drivers shuffled slowly over the Harbor Bridge, their windscreens smeared and filthy.
The cloying dust left many residents of Australia’s most populous city tight-chested with a metallic aftertaste in their mouths as they made their way to work through the haze.
“There is a smell of dust in the air and there is this eerie orange glow in the sky,” Barry Hanstrum, the Bureau of Meteorology’s regional director for New South Wales, said by telephone from Sydney.
The storm was caused when an “intense north low pressure area” formed and generated gale-force westerly winds which “picked up a lot of dust from the very dry interior of the continent,” Hanstrum said.
Orange Cloud
The orange cloud, possibly the city’s worst dust storm on record, may remain over Sydney and the rest of the state for the remainder of the day, he said.
Qantas Airways Ltd., Australia’s largest airline, said in a statement there were “severe delays” to all flights at Sydney airport, with all international arrivals in the city diverted to Brisbane or Melbourne.

Today’s horse racing at Canterbury Park in the city’s southwest was abandoned because of the weather, the Sydney Turf Club said.
The state Ambulance Service said it had experienced an increase in calls from asthma sufferers and some were taken to hospital, the Sydney Morning Herald newspaper reported.
Oakdale, in the city’s southwest, recorded a level of 1,719 on the Department of Environment’s air quality index. A reading of 200 and above is considered hazardous and people with heart or lung disease, the elderly and children should avoid exercising outdoors, according to the department’s Web site.
