Summary

Two three-component ocean bottom seismometers and a current meter were deployed a few hundred meters apart on the southern Blake Plateau off the United States eastern coast to study the effect of near-bottom currents on the background noise level of seismometers. Although analysis of the data is limited somewhat by instrumental problems, the increase in current speed, which ranged from 2 to 25 cm/sec, is correlated with a broadband increase in the noise level at frequencies below 10 Hz. Intermittent periods of narrow-band 8-Hz noise, which were also observed, are not correlative with bottom currents and were tentatively attributed to passing ships. Details of the mechanism of generation of the background noise cannot be determined [...]
