Barstow, N., Sutton, G.H. and Carter, J.A. (1989). Particle motion and pressure relationships of ocean bottom noise: 3900 M depth; 0.003 to 5 HZ. Geophysical Research Letters 16: doi: 10.1029/89GL01618. issn: 0094-8276.

Samples of ocean bottom noise in the frequency band 0.003 to 5 Hz are analyzed for coherency and amplitude and phase relationships among pressure and the tree components of particle motion. Data available from the Columbia-Point Arena ocean bottom seismic station (38¿ 09.2'N, 124¿ 54.4'W) provide examples of different noise conditions. Coherent energy peaks near 0.14, and 0.06 Hz suggest fundamental mode Rayleigh wave motion propagating shoreward. Coherent energy near .30 Hz appears to be variable. Pressure variations near 0.01 Hz and lower frequency correlate with wave heights along the California coast and appear to produce forced deformation of the bottom. ¿ American Geophysical Union 1989
