MRI brain scans use a strong, permanent, static magnetic field to align nuclei in the brain region being studied. Another magnetic field, the gradient field, is then applied to spatially locate different nuclei. Finally, a radiofrequency RF pulse is played to kick the nuclei to higher magnetization levels, with the effect now depending on where they are located.
The oceans as measured by ARGO are warming, but that warming is not only far less than the models predicted, it is far less even than the instrument error. The background of a crucial point … Everyone agrees: The modelers argued the heat was hidden below, that from m-2,m.
Skeptics argue the missing energy was flung out to space. David points out that the errors might be seriously miscalculated. A single ARGO buoy which measures ocean temperatures down to m has an uncertainty of about 0. It would, if the 3, buoys were all measuring the same swimming pool.
But each buoy measures a different piece of ocean, and the ocean does not have one global temperature. So the measurement uncertainty is closer to the instrument error of 0. Going back further, the pre-ARGO data is so bad that longer datasets have much larger uncertainties. But is that warming enough, and how accurately can we measure it anyway?
For some inexplicable reason NOAA publish graphs of ocean heat content OHC but not ocean temperatures — the later are what the equipment measures, and what we relate to. So we need to convert OHC back to degrees C to find out the change in temperature.
ARGO data only properly started inand any data at-depth before then was sparse. Compare it to the detail in our atmospheric measurements.
And vast tracts of the ocean hardly got measured, ever, especially the deepest parts. ARGO data is good, but short.
Since thou shalt not create nor destroy energy — it is fair. That energy has to be somewhere. Where are the error bars? This is the standard diagonal scare-graph for ocean temperatures, but with added notes about which parts are reliable.
Even on the accurate ARGO buoys error margins are probably not a lot less than 0. David found that the rate of warming in the deeper layer is the same as the rate in the top m.Wikipedia talk:WikiProject Elements/Archive 12 Jump to navigation Jump to search.

Resistance is the measure of difficulty regarding current flow through a circuit wire and is determined by type of material (resistivity), the cross sectional area of the given material as well as the length/5(5). Resistance is the slowing down of electric flow (flow of electrons) due to metal ions.
The equation to measure resistance is: Resistance = Voltage Ã· Current R = V / I Resistance is measures in 'volts per amps' or, more commonly, 'Ohms' (Î©).
