A correlation has been found between acoustic scattering intensity at 87.5 kHz and smallscale vertical temperature gradients. Prior to the rise of the Sound Scattering Layer (SSL), there was a positive correlation, which persisted for about an hour after the upward evening SSL migration. After this time a diffuse downward migration was observed until the correlation was significantly negative. Possible rationales for this behavior are suggested.
