The results for this sub-sector are drawn from only three points, two at 1/4 <br />int:h depth, and one at a 5-cm depth, but they are a magnitude higher than any other sub- <br />sector. <br />The highest measurements in the two sectors are on the easterly line that borders Sectors 1 <br />and 2 and includes Sectors 2A, 2B, 2C, 1G, and 1H. <br />Sector l I and the remaining six sub-sectors in Sector I range from the same order of <br />magnitude, but several times lower than the standard, to a magnitude lower than the <br />stzmdard. <br />19 <br /> <br />
