Spearman’s rho correlation results for fish calls per 24-hour at station Gulf 1 (offshore) and environmental variables. SPL is RMS sound pressure level. All test results 2-tailed, n = 15. Note that the test between lunar cycle and water level anomaly is the same test as in Table 7 as only one dataset for each of these variables was available.
*Indicates significant results (p < 0.05).
