ULF/VLF Ocean Bottom Seismo-Acoustics

Abstract

The original research under this contract was directed toward comparison of ocean bottom seismometer and hydrophone data with ocean sub-bottom seismometer data and with appropriate synthetics to determine the effect of sub-bottom structure on the signals received; expected propagation loss; predominant modes of propagation; instrument signal distortion and excess noise; expected spacial coherence; and expected improvement from polarization and array processing. During the first and subsequent years of the contract, research emphasis was re-directed toward analysis interpretation of data from the Columbia-Point Arena ocean bottom seismic station (OBSS) emphasizing the objectives of the ONR Accelerated Research Initiative in ULF/VLF Ocean Seismo-Acoustics.
