My 1979 dissertation was a model relating interannual and interseasonal variations in the shape of the atmosphere, as reflected by the surface barometric pressure field, to variations crop yields across the United States.
The second well permits the syngas produced to escape under pressure to the surface.
FORBES: Underground Coal Gasification: A Trend Worth Watching
Even a relatively small amount of gas a can cause big problems because a gas bubble will expand massively as it moves from high pressure at the seafloor to lower pressure at the surface.
Those plans include robust, multiple barriers between pressure regimes and the surface.
Lufkin, based in Lufkin, Texas, makes pumping equipment that helps drillers extract more oil out of older fields or ones that need to be pumped because the oil and gas underground is not under enough pressure to be forced to the surface naturally.
Even Daniel Vettori, who had such a stranglehold over England for much of the Old Trafford Test, could not build pressure against Pietersen and Ambrose, not helped by the slow surface and failing to record a maiden.
Storm surges have the potential to be dangerous because they involve a great upwelling of a stretch of ocean - intense low pressure at the heart of a storm literally tugs the sea surface above its normal level to create a massive bulge.
Maarten Van Sluys, another member of the Brazilian victims' family association, said there was also concern about the condition of the black boxes after two years sitting in corrosive seawater under immense pressure, nearly 4km (2.5 miles) below the surface of the ocean.
BBC: Air France crash: Tail section found on Atlantic seabed
The surface itself is wonderful and responsive, but the buttons require an unusual amount of pressure to click.
Jean Romagnoli, sports medic and personal trainer working to get the miners in shape for their rescue, said the Phoenix capsule would be hoisted to the surface at a speed of about 60 kilometers per hour and would exert about 2 Gs of pressure on the miners.
"In wintertime, the cliff surface gets so cold that its temperature falls below the freezing point of CO2, which at low pressure goes directly to solid, " said Dr Musselwhite.
As the name implies, it's all based around pressure: a light touch performs the usual commands, while squishing the thumb's wider surface area against the screen allows the equivalent of a multi-touch gesture, such as a pinch to zoom.
