Emergence of a coherent structure from underwater acoustic noise. Estimates of the noise cross-correlation function C12 for the 1–2 path are obtained using various averaging times. The noise averaging time doubles for each subsequent panel and varies from 1/8 of the available data record to the entire record T ≈ 6 days. The estimates of the noise cross-correlation function are shown in relative units. Note the difference between the scales used for C12 in different panels.
