Experimental Observations of Geomagnetic Micropulsations: Land and Sea.

Abstract

Data taken from the second generation of the Naval Postgraduate School's ocean floor and land geomagnetic data collection system is analyzed to determine the wave nature of Geomagnetic Pulsations in the .05 to 10 Hz range. The measurements were made in Monterey, California during June to September 1982. Three of these experiments were twenty-four hours in length. During two such experiments land and sea data were transmitted to a central point where the signals were recorded simultaneously. Geomagnetic fluctuations were analyzed to determine various factors characterizing the waves. These factors include the power spectral densities, coherences, Stokes parameters, orientation angle, degree of polarization, and ellipicity. The software developed in this research provides an extensive capability for analysis of geomagnetic noise. Long term data collection can utilize it to establish trends in both the spatial and temporal properties of naturally occurring ELF electromagnetic fields. (Author)
