Ocean climate change: Comparison of acoustic tomography, satellite altimetry and modeling
-
The North Pacific Acoustic Laboratory (NPAL) experiments were designed to study coherence of acoustic signal propagating long distances in the ocean. The acoustic source was 3000 km from the arrays. The NPAL group provided us with noise data from their receiver array during times when their source was not transmitting. Their array technology is the same used in the Acoustic Thermometry of the Ocean Climate experiments [ATOC Consortium, "Ocean climate change: comparison of acoustic tomography, satellite altimetry and modeling," Science 281, 1327-1332 (1998)].

note
-
The data occasionally showed distinct correlation building up over 20 s intervals. A typical ship might have a source level of 165 dB and at 100 Hz, a transmission loss of order 80 dB (see Ref. 5, p. 12). The ambient noise is about 90 db so that the SNR ∼-5 dB. With a time-bandwidth product √50 (Hz) X 20 (s) →30 dB, we definitely should see occasional distinct correlation patterns compressed by the ship bearing projection onto the line between the two receivers.
