- Kolmogorov-Smirnov tests were used to compare the distribution of these metrics comparing all dives made by each seal with the system pinging relative to when it was not. Table entries provide the Kolmogorov-Smirnov test statistics and for comparisons where dive metrics differed significantly indicate whether the metric was greater with the system pinging (P > NP) or not pinging (NP > P) and indicate the significance level. Kolmogorov-Smirnov tests were also conducted on the average of metrics for all dives conducted during a pinging or non-pinging interval. The small number of such intervals limits the power of these tests, which mostly found non-significant differences, other than three tests (denoted via °) where differences were significant at the p < 0.05 level
