I would like to believe that the broadcasters' collaboration, though deplorable, had nothing to do with government's recent gifts to them of spectrum space worth about $70billion and of regulations permitting unprecedented concentrations of station ownership.
Figure 6 Water depths and sulfate concentrations at station LZ40 from 1 Oct 1999 to 30 Sept 2009.
The areas where the seismic network has the highest concentration of stations are in the Los Angeles and San Francisco areas, but more sensors are needed in rural Northern California, Oregon and Washington.
This maximal concentration varied from station to station but had a mean of 0.8 µM±0.6 µM.
There was a positive, but statistically nonsignificant relationship between the number of wells within 3 km of sampling stations and the maximum CO2 concentration at each station (r = 0.72, p = 0.07).
Figure 4 shows the variation in BC2.5 and PM2.5 concentrations at stations along the Number 7 subway line, which has both underground and aboveground stations on the same subway line.
It focused on four areas with some of the highest concentrations of stations, including Hunts Point in the Bronx, Williamsburg and Greenpoint in Brooklyn, and Jamaica, Queens.
The mean concentrations at stations on the F and 6 subway lines were not significantly different from each other.
The time series graph shows the variations in BC2.5 concentrations at stations during an individual sampling run along the NQR subway line.
The average concentrations in stations TOT, URB and AGR were 0.076 nmol/L, 0.119 nmol/L and 0.073 nmol/L, respectively.
The PM2.5 mean ± SD concentrations for stations on the F, E, and 6 subway lines were very elevated: 139.3 ± 63.1, 64.8 ± 37.5 and 106.9 ± 31.3 μg/m, respectively.
