Fluctuations in the horizontal component of the earth's magnetic field were measured at a land site (La Mesa) and on the floor of Monterey Bay at a depth of 70 meters. The measurements span a 19-9hour period (August 17/18, 1982). Assuming a circular polarization basis set, analysis was conducted to determine the coherence between the two sites in the frequency range .05-10 Hz. Preliminary analysis indicates a high degree of coherence from .05-.4 Hz. Also, a study of the polarization of the micropulsation field at each site was conducted in terms of Stokes parameters.
