PCB Example 5--Map 3

Maps of PCB concentration in South Central sector of Hudson River. Because PCB concentration is first transposed by anamorphosis into a standard normal distribution, the mean is known to be zero and we can use simple kriging to estimate the concentration.

3. Probability that the PCB concentration exceeds 25 micrograms/cc. Blue = probability less than 50%, Yellow = probability between 50% and 90%, and Red = probability exceeds 90%.
