a.
Only data from samples collected more than 50 m from the beach were used in
this tabulation.
b.
nis the number of samples used to compute the mean.
c.
na = not analyzed; ns = not significant.
Single sample (n=1)
errors are two-sigma, propagated, counting errors, whereas the error for
more than one (n>1) sample is one standard deviation of the mean.
